name	build-test-verify
description	Build the project, run tests, lint, format, spell check, generate mocks, or verify the build passes for Bitwarden iOS. Use when asked to "build", "run tests", "lint", "format", "verify build", "check if it compiles", "run swiftlint", "run swiftformat", "generate mocks", or to execute any part of the build/test/verify pipeline.

Build, Test, and Verify — Bitwarden iOS

Initial Setup

brew bundle                  # Install Homebrew dependencies
./Scripts/bootstrap.sh       # Generate Xcode projects, install Mint packages, set up git hooks

Git hooks set up by bootstrap.sh:

• post-checkout / post-merge — automatically re-run bootstrap.sh

Project Generation

.xcodeproj files are gitignored and must be generated before building:

mint run xcodegen --spec project-pm.yml    # Password Manager
mint run xcodegen --spec project-bwa.yml   # Authenticator
mint run xcodegen --spec project-bwk.yml   # BitwardenKit
mint run xcodegen --spec project-bwth.yml  # Test Harness

Or run all at once via ./Scripts/bootstrap.sh.

Building

./Scripts/build.sh project-pm.yml Bitwarden Simulator       # PM for simulator
./Scripts/build.sh project-bwa.yml Authenticator Simulator   # Authenticator for simulator
./Scripts/build.sh project-bwth.yml TestHarness Simulator    # Test Harness for simulator
./Scripts/build.sh project-pm.yml Bitwarden Device           # PM for device

Running Tests

Always read the simulator config files before running tests:

DEVICE=$(tr -d '\n' < .test-simulator-device-name)
OS=$(tr -d '\n' < .test-simulator-ios-version)

Then run tests with:

xcodebuild test \
  -workspace Bitwarden.xcworkspace \
  -scheme Bitwarden \
  -testPlan Bitwarden-Default \
  -destination "platform=iOS Simulator,name=$DEVICE,OS=$OS"

Current values (as of last update): device iPhone 17 Pro, OS 26.2. Do not hardcode these — always read from .test-simulator-device-name and .test-simulator-ios-version at runtime, as they change when the project upgrades its simulator target.

CI runs all -Default test plans on PRs to main, commits to main, and release branches. Test execution order is randomized (randomExecutionOrder: true).

Snapshot tests are currently disabled. Do not run or re-record them. If you encounter a snapshot test, prefix the function name with disable (e.g., disabletest_snapshot_defaultState).

Lint, Format, Spell Check

mint run swiftlint                        # Lint (custom rules: todo_without_jira, weak_navigator, style_guide_font)
mint run swiftformat .                    # Auto-fix formatting (4-space indent, Swift 6.2)
mint run swiftformat --lint --lenient .   # Check formatting without fixing
typos                                     # Spell check

SwiftLint and SwiftFormat run automatically as post-compile scripts (configured in project-pm.yml).

Code Generation

Run automatically in pre-build phases; trigger manually when needed:

# Mock generation — run from an Xcode build phase (BUILD_DIR is set automatically by Xcode)
# To run standalone, supply BUILD_DIR manually — see the script header for the one-liner
./Scripts/generate-mocks.sh BitwardenShared    # default if argument omitted
./Scripts/generate-mocks.sh AuthenticatorShared
./Scripts/generate-mocks.sh BitwardenKit

# Asset/localization code generation
mint run swiftgen config run --config swiftgen-bwr.yml   # BitwardenResources (most common)
mint run swiftgen config run --config swiftgen-pm.yml    # Password Manager
mint run swiftgen config run --config swiftgen-bwa.yml   # Authenticator
mint run swiftgen config run --config swiftgen-bwth.yml  # Test Harness

Tooling Reference

Tool	Config	Purpose
XcodeGen	project-*.yml	Generates .xcodeproj from YAML specs
Mint	Mintfile	Swift tool package manager
SwiftLint	.swiftlint.yml	Linting with custom rules
SwiftFormat	.swiftformat	Code formatting
Sourcery	*/Sourcery/sourcery.yml	Mock generation (AutoMockable)
SwiftGen	swiftgen-*.yml	Asset/localization code generation
typos	project config	Spell checking
Fastlane	fastlane/Fastfile	CI/CD automation

Common Failures

Problem	Cause	Fix
.xcodeproj not found	Files are gitignored	Run ./Scripts/bootstrap.sh
MockXxx not found	Sourcery not run	Add // sourcery: AutoMockable, run Sourcery or build
Snapshot test runs	Snapshots are currently disabled	Prefix function name with disable (e.g., disabletest_snapshot_defaultState)
Extension crash on unlock	Argon2id KDF > 64 MB	Check maxArgon2IdMemoryBeforeExtensionCrashing in Constants.swift
SwiftLint TODO warning	Missing JIRA ticket	// TODO: PM-12345 - description

Debug Tips

• Error reporting: ErrorReporter protocol + OSLogErrorReporter for development
• Flight recorder: In-app logging for debugging production issues
• SDK diagnostics: Xcode console errors prefixed BitwardenSdk
• Network debugging: Set breakpoints in APIService implementations in Networking/
• State debugging: print(subject.state) in processor tests to inspect state changes
