Individual skill

developing-ios-apps

Builds and ships iOS/macOS apps with XcodeGen, SwiftUI and SPM: Xcode build fixes, device deployment, Apple Developer signing/notarization, CI/CD pipelines. Use for XcodeGen project.yml setup, "Library not loaded @rpath" crashes, code-signing errors (Error -25294, adhoc fallback), or Electron notarization failures. Not for TCC permission dialogs (use macos-permissions) or disk cleanup (use macos-cleaner).

# iOS App Development

Build, configure, and deploy iOS applications using XcodeGen and Swift Package Manager.

## Critical Warnings

| Issue | Cause | Solution |
|-------|-------|----------|
| "Library not loaded: @rpath/Framework" | XcodeGen doesn't auto-embed SPM dynamic frameworks | **Build in Xcode GUI first** (not xcodebuild). See [Troubleshooting](#spm-dynamic-framework-not-embedded) |
| `xcodegen generate` loses signing | Overwrites project settings | Configure in `project.yml` target settings, not global |
| Command-line signing fails | Free Apple ID limitation | Use Xcode GUI or paid developer account ($99/yr) |
| "Cannot be set when automaticallyAdjustsVideoMirroring is YES" | Setting `isVideoMirrored` without disabling automatic | Set `automaticallyAdjustsVideoMirroring = false` first. See [Camera](#camera--avfoundation) |
| App signed as adhoc despite certificate | `@electron/packager` defaults `continueOnError: true` | Set `continueOnError: false` in osxSign. See [Code Signing](#macos-code-signing--notarization) |
| "Cannot use password credentials, API key credentials..." | Passing `teamId` to `@electron/notarize` with API key auth | **Remove `teamId`**. `notarytool` infers team from API key. See [Code Signing](#macos-code-signing--notarization) |
