| "App Intents are just a protocol conformance" | App Intents have parameter validation, entity queries, and background execution. |
| "Widgets are simple, I've done them before" | Widgets have timeline, interactivity, and Live Activity patterns that evolve yearly. |
| "Localization is just String Catalogs" | Xcode 26 has type-safe localization, generated symbols, and #bundle macro. |
| "Push notifications are just a payload and a token" | Token lifecycle, Focus levels, service extension gotchas cause 80% of push bugs. |
| "I'll just bundle the assets, it's simpler" | Bundling ≥10 MB inflates first-install size and pays the cost every update. Background Assets ships with App Store install-progress integration; FM adapters can't be bundled at all. See skills/background-assets.md. |
| "I'll use URLSession for the asset download" | URLSession doesn't integrate with App Store install progress, charging-aware scheduling, or per-app quota — and can't reach Apple-hosted asset packs at all. Background Assets is the supported channel. |
| "On-Demand Resources still works fine" | The entire NSBundleResourceRequest family is deprecated in the 27 SDKs ("Use Background Assets instead"). Migrate ODR tags to asset packs. See skills/background-assets.md. |
| "Just request full Calendar access" | Most apps only need to add events — EventKitUI does that with zero permissions. |
| "I'll request Bluetooth permission and scan for the accessory" | AccessorySetupKit (iOS 18+) pairs in one tap with no broad Bluetooth prompt and grants scoped BT+Wi-Fi access. See skills/accessorysetupkit.md. |
| "I'll process the VoIP push, then report the call when ready" | iOS terminates your app and stops delivering VoIP pushes if a push doesn't report a call before completion. Report first, fetch after. See skills/callkit-livecommunicationkit.md. |
| "I'll activate the audio session when the call connects" | CallKit owns the audio session — activate only in provider(_:didActivate:) or audio is silent/misrouted. See skills/callkit-livecommunicationkit.md. |
| "I'll use CNContactStore directly for picking" | CNContactPickerViewController needs no authorization and shows all contacts. |
