Create a production-ready macOS application project. Walk the user through interactive choices, then generate all files.
$ARGUMENTS[0] = App name (e.g., MyApp)$ARGUMENTS[1] = Bundle ID (e.g., me.xueshi.myapp)If arguments are missing, ask the user before proceeding.
Ask questions in this exact order. Present each step clearly with numbered/lettered options and defaults in bold. Wait for user response before proceeding to the next step. You may combine steps 3 and 4 into a single message if appropriate, presenting them as a checklist.
Ask the user:
I can scaffold this two ways: A) From the template repo (default, fastest, fewest tokens) — clones
XueshiQiao/macos-app-starterand applies a small rename + customization diff. Best when your needs match the template's flavor (Menu Bar + Window hybrid, Sparkle, signed CI, full i18n, MIT, no sandbox). B) From scratch — generates every file from the templates in this skill. Best when your archetype/feature mix is far from the template (e.g., Menu Bar only, no Sparkle, sandboxed, no localization).Which would you like? (default A)
If the user picks A (template), follow "Generation Path A: Template Clone" below — most steps simplify to "delete the parts you don't need" and "rename".
If the user picks B (from-scratch), follow the existing Step 1 → Step 5 flow and the Generation Rules section.
The template's exact flavor (so you can judge fit on the user's behalf):
If 5+ of these don't match what the user wants, recommend B.
me.xueshi.<appname-lowercase>)Ask user to pick one:
LSUIElement: true, NSStatusItem, no dock iconDefault: A
Ask once. Most apps don't need a separate helper process; the default is None and you should not push users toward the other options. Show this table when asking:
| Option | What you get | Runs as | Approval | When to pick it | Limits / cost |
|---|---|---|---|---|---|
| A) None (default) | Single-process app. | user | n/a | 90% of apps. Anything you can do inside the main app process. | none |
B) Login Item (SMAppService.mainApp) | Main app auto-launches at login. | user | none | Menu bar tools, chat clients, quick-capture apps that the user wants opened automatically. | Adds zero capability — only convenience. |
C) User Agent (SMAppService.agent) | Separate LaunchAgent helper binary; launchd starts it on demand once the user has logged in. App ↔ helper via XPC. | user | none | Persistent background work that doesn't need root: clipboard watcher, sync engine, global hotkey daemon, on-device AI worker. | Two-process complexity, must design XPC protocol, helper signed with same Team ID. |
D) Privileged Daemon (SMAppService.daemon) | Separate LaunchDaemon helper binary; launchd starts it on demand at the system level (no login required). App ↔ helper via privileged XPC. | root | user must approve in System Settings | VPN / packet filter, system-wide network proxy, kext-adjacent ops, services that must run before any user logs in (set RunAtLoad for that case). | High MAS review bar, helper effectively unsandboxable, runtime XPC caller authorization is your responsibility (see HelperMain.swift), user-visible approval flow. |
Default: A (None). Confirm explicitly before generating C or D. If the user picks D, ask one verification question: "Which specific operation needs root?" — if they cannot name one, steer them to C.
If C is selected, copy templates/agent/ files into the project (see "Background
Helper Templates" section below).
If D is selected, copy templates/daemon/ files (and tell the user about the
System Settings approval step).
If A or B is selected, skip the helper templates entirely.
Present as a checklist. User can accept defaults or customize:
| Feature | Default | Notes |
|---|---|---|
| Runnable starter app | Yes | Generates compilable Swift source files |
XcodeGen (project.yml) | Yes | Single source of truth for build config |
| App Sandbox | No | Required for App Store. Incompatible with Accessibility API, CGEvent tap, etc. Tell the user this trade-off. |
| SPM dependencies | Yes | Ask which: GRDB, KeyboardShortcuts, Sparkle, etc. |
| SwiftLint config | No | Generates .swiftlint.yml with sensible defaults |
| Unit test target | Yes | XCTest skeleton with one example test |
| Launch at Login | Yes if menu bar archetype, No otherwise | Uses SMAppService |
| Accessibility permission gate | No | Startup permission check + prompt (for apps using CGEvent tap, AXUIElement, etc.) |
| Screen Recording permission flow | No | For apps using ScreenCaptureKit (SCShareableContent, SCStream). Generates ScreenRecordingPermission.swift + a 3-state modal (ScreenRecordingPromptView.swift) that handles the mandatory relaunch on first grant. NOT a substitute for the Accessibility gate — first-grant semantics differ. |
| Localization | No | If yes, ask which languages (always includes English). Generates Localizable.xcstrings or .strings. |
| File-based logging | Yes | ~/Library/Logs/<AppName>.log with lightweight FileLog class |
| Settings/Preferences window | Yes | SwiftUI Settings scene scaffold |
| Analytics (Aptabase) | No | Privacy-respecting event tracking |
| Onboarding/Welcome window | No | First-launch experience window |
| Feature | Default | Condition | Notes |
|---|---|---|---|
| Apple Developer Account | Yes | — | If NO: skip code signing, notarization, and stapling in CI. Build unsigned only. |
| GitHub Actions CI/CD | Yes | — | Build pipeline. If no Apple account, builds unsigned universal binary only. |
Auto release on v* tags | Yes | Requires CI/CD | softprops/action-gh-release@v2 |
| Release notes languages | English | Requires auto release | User can add more: Chinese, Japanese, German, etc. |
| Auto-update mechanism | None | Requires CI/CD + Apple account | A) GitHub API polling (lightweight) B) Sparkle (full-featured, requires SPM dep) C) None |
| Homebrew Cask formula | No | Requires CI/CD | Template .rb file for brew install --cask. If yes, ALSO ask the tap-topology question below. |
| License | MIT | — | MIT / GPL-3.0 / Apache-2.0 / None |
Modern Homebrew (5.x) refuses to install casks from arbitrary paths — they must live in a tap. Asking up front avoids generating a cask file in a location nobody can install from. Present these four options:
| Option | Where the .rb lives | Install command users will run | When to pick |
|---|---|---|---|
| A) Existing shared tap (default if user has one) | <owner>/homebrew-tap/Casks/<name>.rb (separate repo) | brew install --cask <owner>/tap/<name> | User already publishes other casks from one shared tap. Ask for <owner> and confirm the repo name. |
| B) New per-app tap | <owner>/homebrew-<name>/Casks/<name>.rb (new separate repo) | brew install --cask <owner>/<name>/<name> | First cask, no shared tap yet, prefer per-app isolation. The skill scaffolds the tap repo skeleton (README + Casks/), but the user must gh repo create it. |
| C) Submit to homebrew/cask | upstream Homebrew/homebrew-cask PR | brew install --cask <name> | App is signed, notarized, has public releases, and has a working livecheck. Skill writes the cask + a checklist; user opens the PR manually. Note: brew audit --new rules apply only here. |
| D) Template only | Casks/<name>.rb in the app repo (NOT installable as-is) | n/a | User wants to decide later. README will document this is a draft and not a working install. |
Default: A if the user names an existing tap, otherwise B.
Capture: cask_topology ∈ {shared_tap, per_app_tap, homebrew_cask, template_only},
tap_owner (for A/B), tap_repo_name (for A: usually homebrew-tap; for B: homebrew-<name>).
These values drive: where the .rb is written, the README install command,
the CI cask-bump step's target repo, and which validation commands appear in
the post-generation summary.
| README.md | Yes | — | With badges (build status, macOS version, license), install instructions, screenshots section |
These are always created regardless of choices:
git init + .gitignoreAGENTS.md (project conventions) + CLAUDE.md symlink → AGENTS.mdUse this when the user picked A in Step 0. This is dramatically cheaper in tokens because the template repo holds all the boilerplate.
Clone via GitHub template:
gh repo create <OwnerOrUser>/<NewRepoName> --template XueshiQiao/macos-app-starter --public --clone
cd <NewRepoName>
If the user wants the project locally without creating a GitHub repo yet, use gh repo clone + delete-remote pattern, or git clone --depth=1 + rm -rf .git && git init.
Rename. Find-and-replace across the repo:
MacOSAppStarter → <AppName>dev.xueshi.macos-app-starter → <BundleID>macosappstarter (lowercase, in cask file) → <appname-lowercase>XueshiQiao → user's GitHub owner (in README badges, AGENTS.md, cask file URL, and project.yml's SUFeedURL)macos-app-starter → user's repo name (in SUFeedURL and any GitHub-Releases-asset URLs in workflow)LICENSE copyright holderAbout SUFeedURL: the template ships with the raw GitHub URL pattern (https://raw.githubusercontent.com/<owner>/<repo>/main/appcast.xml). CI generates appcast.xml on every tagged release and commits it back to main with [skip ci]. This matches the production pattern in AnyDrag, PastePawX, HyperCapsLock. Do NOT swap to a github.io URL unless Pages is actually set up — that's the failure mode that broke the first version of this template.
Sparkle keypair MUST be regenerated. The template ships with SUPublicEDKey matching a throwaway private key stored as the template repo's SPARKLE_EDDSA_KEY secret. Forks that don't regenerate are accepting updates signed by anyone who can read the template repo's secret history — bad. The README's "Setup before you ship" step covers the regeneration commands.
Aptabase key MUST be replaced. The template ships with the maintainer's real Aptabase key (A-US-3800930688) so events flow to a known dashboard during template development. Forks that don't replace it will leak their users' app-launch events into the maintainer's project.
Files to touch (all done with Edit):
project.ymlCasks/macosappstarter.rb (rename file too)LICENSEREADME.mdAGENTS.md (which CLAUDE.md symlinks to)MacOSAppStarter/Sources/ (the MacOSAppStarter directory itself must also be renamed to <AppName>/)MacOSAppStarter/Resources/MacOSAppStarter.entitlements (rename file)MacOSAppStarterTests/MacOSAppStarterTests.swift (rename test class + dir)Localizable.xcstrings and InfoPlist.xcstrings (only the literal app name strings)Apply user-chosen customizations. For each thing the user opted out of, delete the corresponding files/sections:
| If user said NO to | Delete / modify |
|---|---|
| Menu Bar archetype (windowed only) | AppDelegate.swift (status item code), shrink to plain NSApplicationDelegate. Set LSUIElement: false (already false in template). Remove menu bar popover code. |
| Window archetype (menu bar only) | Remove main WindowGroup from MacOSAppStarterApp.swift. Set LSUIElement: true. Remove ContentView.swift. |
| Sparkle | Remove SPM dep, UpdateManager.swift, Update tab in Settings, Check for Updates… menu command. |
| KeyboardShortcuts | Remove SPM dep, hotkey registration in AppDelegate, Shortcuts tab in Settings. |
| Aptabase | Remove SPM dep, Analytics.swift, analytics toggle in Settings. |
| Onboarding | Remove OnboardingView.swift and the first-launch trigger in AppDelegate. |
| Accessibility gate | Remove AccessibilityChecker.swift and references in ContentView/OnboardingView. |
| Screen Recording permission | Remove ScreenRecordingChecker.swift (or ScreenRecordingPermission.swift) and any SCShareableContent / SCStream / SCScreenshotManager call sites. Drop the import ScreenCaptureKit line. |
| File logging | Remove FileLog.swift and all call sites (replace with os.Logger only). |
| Localization | Remove Localizable.xcstrings, InfoPlist.xcstrings, LocalizationManager.swift. Strip String(localized:) calls back to bare strings. Remove knownRegions from project.yml. |
| Launch at Login | Remove LaunchAtLoginManager.swift and toggle in Settings. |
| Settings window | Remove SettingsView.swift and Settings { ... } scene. |
| SwiftLint | Delete .swiftlint.yml. |
| Unit tests | Delete MacOSAppStarterTests/ and remove from project.yml. |
| Homebrew Cask | Delete Casks/. |
| CI/CD | Delete .github/workflows/build.yml. |
For things the user opted in to that aren't in the template (e.g. App Sandbox, Background Helper, GRDB), fall back to the templates in ## File Templates below — generate just those pieces.
Regenerate the Xcode project — xcodegen generate. Then build to verify nothing was broken by the rename: xcodebuild -scheme <AppName> -destination 'platform=macOS' build.
Sparkle keys, Aptabase key, Apple Developer secrets — same as the from-scratch path. The template ships placeholders; tell the user which to replace.
Re-init git if the user wants a clean history: rm -rf .git && git init && git add . && git commit -m "Initial commit (from macos-app-starter template)".
If the user's choice mix differs significantly from the template (Step 0 lists the exact flavor), recommend Path B instead — the template-deletion overhead may exceed the cost of generating the matching set from scratch. Rough rule: if 5+ of the template's choices are wrong for the user, prefer Path B.
Use this when the user picked B in Step 0. The rest of this document — the existing Generation Rules, File Templates, and Background Helper Templates sections — describes Path B.
After collecting all answers, generate files in the project directory (current working directory + /<AppName>/).

install command uses (e.g., <owner>/tap/<name> for shared tap).brew audit --cask --new --online <tap-ref>.
The --new flag enforces the homebrew/cask main rules (popularity,
verified: placement, etc.) and should be ignored for personal taps —
they don't apply there.brew tap <owner>/<short> then brew install --cask <full-ref> to verify end-to-end.# Xcode

Use the templates in
skills/macos-app-scaffold-new/templates/screen-recording/ —
ScreenRecordingPermission.swift, ScreenRecordingPromptView.swift, and a
README.md documenting the gotchas. Read the README before generating.
The single non-negotiable invariant the manager encodes: on first grant,
ScreenCaptureKit (SCShareableContent, SCStream, SCScreenshotManager)
will NOT start working in the same process. The user MUST quit and relaunch.
Do not write a flow that polls SCShareableContent after grant — it does
not work, and "polling longer" does not fix it.
The manager exposes three states — notGranted, grantedPendingRelaunch,
granted — which the prompt view maps to three branches: explain → "Open
Settings" → poll → "Relaunch Now". Wire ScreenRecordingPromptView as a
.sheet(isPresented:) from any feature entry point that needs screen
capture. Gate all ScreenCaptureKit calls on
ScreenRecordingPermission.shared.isReadyForCapture (the canonical
helper) — never on status != .notGranted, which lets
.grantedPendingRelaunch through and produces silent failures.
When generating, also add this to the project's debug config:
# project.yml
configs:
Debug: debug
settings:
configs:
Debug:
CODE_SIGN_IDENTITY: "Apple Development" # NOT "-" (ad-hoc)
DEVELOPMENT_TEAM: <user's Team ID>
Reason: ad-hoc / changing-identity rebuilds wipe the TCC entry silently, which is the dev-loop bug that costs everyone a day the first time.
Do NOT add NSScreenRecordingUsageDescription to Info.plist. It is not
consulted by this API.

Notes for whoever maintains this:
perl -i is used over sed -i because sed -i syntax differs between
GNU and BSD/macOS. The runner is macOS, so this matters.brew bump-cask-pr produces, so
anyone later switching to PR-flow gets consistent history.gh repo create the tap repo before the first
tag push; otherwise the clone step fails. Document this in the post-generation
summary's "Next steps".If multiple languages are selected, create a RELEASE_TEMPLATE.md at project root:

### English

### {{Language2}} (e.g., Chinese / 中文)
-
And add to AGENTS.md a convention:
Release notes must include sections for each configured language: {{list of languages}}.
Where the file goes depends on cask_topology from Step 4a:
cask_topology | Path the skill writes |
|---|---|
shared_tap (A) | The skill canNOT write to a sibling repo on disk. Print the cask body and instruct: "Save this as Casks/{{appname-lowercase}}.rb in your {{tap_owner}}/{{tap_repo_name}} repo and push." |
per_app_tap (B) | Scaffold a sibling repo skeleton at ../homebrew-{{appname-lowercase}}/ containing Casks/{{appname-lowercase}}.rb, a minimal README.md, and .gitignore. Tell the user to cd ../homebrew-{{appname-lowercase}} && gh repo create {{tap_owner}}/homebrew-{{appname-lowercase}} --public --source=. --push. |
homebrew_cask (C) | Write to Casks/{{appname-lowercase}}.rb in the app repo as a working draft, plus a HOMEBREW_CASK_PR_CHECKLIST.md (see below). The user copies the cask into a homebrew-cask fork to open the PR. |
template_only (D) | Write to Casks/{{appname-lowercase}}.rb in the app repo with a comment header marking it as a draft. README must reflect that this is not yet installable. |
Template (used in all four cases — the only difference is where it lands):
cask "{{appname-lowercase}}" do
version "1.0.0"
sha256 ""
url "https://github.com/{{GitHubOwner}}/{{GitHubRepo}}/releases/download/v#{version}/{{AppName}}.dmg"
# Add `verified:` ONLY when url's host differs from homepage's host (current
# audit rule). Both this template's url and homepage point at github.com, so
# `verified:` here is unnecessary and will be flagged by `brew audit`. If you
# later host the DMG on a different domain, add e.g.:
# verified: "github.com/{{GitHubOwner}}/{{GitHubRepo}}/"
name "{{AppName}}"
desc "{{one-line description, ≤80 chars, no trailing period, no app name}}"
homepage "https://github.com/{{GitHubOwner}}/{{GitHubRepo}}"
# --- livecheck block: emit ONE of the two variants below ---
# If auto_update_mechanism == "sparkle": use the :sparkle variant. The url
# MUST match SUFeedURL in Info.plist. The recommended pattern is to host
# the appcast as a GitHub Release asset:
# https://github.com/<owner>/<repo>/releases/latest/download/appcast.xml
# so this livecheck url and the SUFeedURL are identical. Do NOT swap to
# a guessed github.io URL — Pages is not on by default, and users without
# Pages set up will get 404s. If the user has set up Pages explicitly, then
# use their actual hosted URL.
# If auto_update_mechanism == "github" or "none": use the :github_latest variant.
# Variant A — Sparkle:
livecheck do
url "{{appcast-feed-url-from-SUFeedURL-or-TODO}}"
strategy :sparkle
end
# Variant B — GitHub releases:
livecheck do
url :url
strategy :github_latest
end

# apps and for any app that polls GitHub Releases internally.

For topology B (per_app_tap), also create the sibling repo skeleton:

`../homebrew-{{appname-lowercase}}/.gitignore`:
.DS_Store
**For topology C (`homebrew_cask`)**, also create `HOMEBREW_CASK_PR_CHECKLIST.md` at project root listing: signed + notarized release present, livecheck verified with `brew livecheck --cask Casks/{{appname-lowercase}}.rb`, `brew audit --cask --online --new Casks/{{appname-lowercase}}.rb` clean, fork `Homebrew/homebrew-cask`, copy the file to `Casks/{{first-letter}}/{{appname-lowercase}}.rb` (note the alphabetized subdirectory), open PR titled `Add {{appname-lowercase}} <version>`.

## Installation
### Download
Download the latest `.dmg` from [Releases](https://github.com/{{GitHubOwner}}/{{GitHubRepo}}/releases).
### Homebrew (if cask is generated)
Render the install command according to `cask_topology`:
- **A) shared_tap**: `brew install --cask {{tap_owner}}/tap/{{appname-lowercase}}`
(assumes `tap_repo_name` = `homebrew-tap`; brew auto-prepends the
`homebrew-` prefix from the second segment, so users type `tap`, not the full repo name)
- **B) per_app_tap**: `brew install --cask {{tap_owner}}/{{appname-lowercase}}/{{appname-lowercase}}`
- **C) homebrew_cask** (after PR is merged): `brew install --cask {{appname-lowercase}}`
- **D) template_only**: omit this section entirely, OR include it with a
prominent note: `<!-- Cask template generated but not yet published. The bare
command below requires homebrew/cask submission; see Casks/{{appname-lowercase}}.rb. -->`
```bash
brew install --cask {{rendered-from-topology}}
brew install xcodegen
xcodegen generate
open {{AppName}}.xcodeproj
# Cmd+R to build and run
Adapt badges based on license choice and macOS version.
### AGENTS.md
Generate project-specific conventions. Always include:
```markdown
# Agent Guidelines for {{AppName}}
## Single Source of Truth
`project.yml` is the ONLY source of truth for project configuration. Do NOT edit
`.pbxproj` or `Info.plist` directly. Modify `project.yml` and run `xcodegen generate`.
## Build & Run
```bash
brew install xcodegen
cd {{project-root-if-nested}}
xcodegen generate
open {{AppName}}.xcodeproj # Cmd+R to run

Add to project.yml packages:
Aptabase:
url: https://github.com/nicklama/aptabase-swift
majorVersion: 0.3.0
Add initialization in AppDelegate.applicationDidFinishLaunching:
import Aptabase
Aptabase.shared.initialize(appKey: "YOUR_APTABASE_KEY")
File: {{AppName}}/Sources/WelcomeView.swift
import SwiftUI
struct WelcomeView: View {
@Environment(\.dismiss) private var dismiss
var body: some View {
VStack(spacing: 24) {
Image(systemName: "app.fill")
.font(.system(size: 64))
.foregroundStyle(.tint)
Text("Welcome to {{AppName}}")
.font(.largeTitle)
.fontWeight(.bold)
Text("Brief description of what the app does.")
.font(.title3)
.foregroundStyle(.secondary)
.multilineTextAlignment(.center)
Button("Get Started") {
UserDefaults.standard.set(true, forKey: "hasCompletedOnboarding")
dismiss()
}
.buttonStyle(.borderedProminent)
.controlSize(.large)
}
.padding(40)
.frame(width: 480, height: 360)
}
}
Add to AppDelegate: check UserDefaults.standard.bool(forKey: "hasCompletedOnboarding") and show welcome window if false.
The modern stack (Xcode 15+) uses String Catalogs (.xcstrings). They auto-extract strings from String(localized:) calls at build time and provide a UI for translation. Prefer them over legacy .strings/.stringsdict.
1. project.yml additions:
settings:
base:
LOCALIZATION_PREFERS_STRING_CATALOGS: YES
DEVELOPMENT_LANGUAGE: en # or whatever the base language is
SWIFT_EMIT_LOC_STRINGS: YES # auto-extract String(localized:) at build time
# All selected languages must appear in `knownRegions` so Xcode picks them up.
# These are BCP-47 codes: en, zh-Hans, zh-Hant, ja, ko, de, fr, es, pt-BR, ...
options:
knownRegions:
- en
- {{Language2}} # e.g. zh-Hans
- Base # required by Xcode for resource loading
sources:
- path: {{AppName}}/Sources
- path: {{AppName}}/Assets.xcassets
- path: {{AppName}}/Resources
2. {{AppName}}/Resources/Localizable.xcstrings — one file with all UI strings. Skeleton:
{
"sourceLanguage" : "en",
"strings" : {
"Settings" : {
"extractionState" : "manual",
"localizations" : {
"en" : { "stringUnit" : { "state" : "translated", "value" : "Settings" } },
"zh-Hans" : { "stringUnit" : { "state" : "translated", "value" : "设置" } }
}
}
},
"version" : "1.0"
}
After the first build with SWIFT_EMIT_LOC_STRINGS: YES, Xcode auto-fills new strings from String(localized:) calls. The skill should seed the file with strings for every UI string in generated Swift files (Settings, Onboarding, menu items, etc.).
3. {{AppName}}/Resources/InfoPlist.xcstrings — separate catalog for plist values like CFBundleDisplayName, CFBundleName, menu bar status item title. Required when you want the app's display name to be localized:
{
"sourceLanguage" : "en",
"strings" : {
"CFBundleDisplayName" : {
"localizations" : {
"en" : { "stringUnit" : { "state" : "translated", "value" : "{{AppName}}" } },
"zh-Hans" : { "stringUnit" : { "state" : "translated", "value" : "{{ChineseAppName}}" } }
}
}
},
"version" : "1.0"
}
In Info.plist (or via XcodeGen infoPlist:), set CFBundleDisplayName to $(CFBundleDisplayName) so it's resolved from the catalog.
4. Swift usage:
// Preferred — String Catalogs auto-extract these.
Text("Settings") // SwiftUI: implicit localization
let title = String(localized: "Welcome") // explicit
let n = String(localized: "\(count) items") // interpolation works
// Avoid: NSLocalizedString (older API; still works but not auto-extracted as cleanly)
// Avoid: bare String literals shown in UI without going through String(localized:)
5. Runtime language switch (optional but common UX). macOS apps inherit system language by default; many users want an in-app language picker. Provide a helper:
// {{AppName}}/Sources/LocalizationManager.swift
import Foundation
import SwiftUI
@MainActor
final class LocalizationManager: ObservableObject {
static let shared = LocalizationManager()
@AppStorage("app.language") var languageCode: String = "" {
didSet { applyLanguage() }
}
private init() { applyLanguage() }
private func applyLanguage() {
// Empty string = follow system. Non-empty = override via AppleLanguages.
if languageCode.isEmpty {
UserDefaults.standard.removeObject(forKey: "AppleLanguages")
} else {
UserDefaults.standard.set([languageCode], forKey: "AppleLanguages")
}
// Note: system-resolved Bundle.main strings only update on next launch.
// For instant switching, observe `objectWillChange` and key SwiftUI views by `languageCode`.
objectWillChange.send()
}
}
Then key the root view by localizationManager.languageCode (.id(...) in SwiftUI) so the view tree rebuilds on switch — strings re-resolve through String(localized:)'s lookup chain.
6. AGENTS.md convention — add this so future code stays localizable:
All UI strings must go through
String(localized:)(or SwiftUI implicitText("...")). Never use bareStringliterals for text shown to users. New strings appear automatically inLocalizable.xcstringsafter build; translate non-English entries before merging.
7. Release notes — when multiple languages are configured, the release notes template (see "Release Notes Languages" above) should have a section per language so changelog text matches what Sparkle (or the user) shows.
Only use this section if the user picked C (User Agent) or D (Privileged Daemon) in Step 2.5. For A and B, skip entirely.
