developing-ios-apps
Develops iOS/macOS apps with XcodeGen, SwiftUI, and SPM, including Apple Developer signing, notarization, and CI/CD pipelines. Use when building iOS/macOS apps, fixing Xcode build failures, deploying to real devices, or configuring CI/CD signing. Triggers on XcodeGen project.yml, SPM dependency issues, code signing errors (Error -25294, keychain mismatch, adhoc fallback, EMFILE, notarization credential conflict), "Library not loaded @rpath", Electron @electron/osx-sign / @electron/notarize, notarytool, or certificate/provisioning problems.

What this skill does
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 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 App signed as adhoc despite certificate @electron/packager defaults continueOnError: true Set continueOnError: false in osxSign. See Code Signing "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 EMFILE during signing (large embedded runtime) @electron/osx-sign traverses all files in .app bundle Add ignore filter + ulimit -n 65536 in CI.
