Solving iOS Code Signing, Swift Linker, and Target-ID Conflicts in Headless CI/CD

The Challenge: Automating iOS releases inside a headless GitHub Actions runner compiled successfully but repeatedly crashed during archiving and TestFlight uploading.

Root Causes:

1. Godot exports a pure Objective-C project, but modern SDKs (like AdMob) use Swift, causing linker failures for symbols like __swift_FORCE_LOAD_$_swift_Builtin_float.
2. By default, Godot projects trigger automatic developer signing which conflicts with manual Distribution certificates on the headless server.
3. Xcode versions in older runners do not bundle the required modern Swift 6.0 SDK tools.

To build, sign, and upload a Godot iOS project headlessly inside GitHub Actions:

1. Target the correct modern SDK Runner: Use macos-26 (which provides Xcode 26.5 and the required iOS 26 SDK).
2. Bypass automatic signing from the command line: Force manual code signing, map your Team ID, and specify the Provisioning Profile name explicitly:

   xcodebuild -project MazePoint.xcodeproj \
     -scheme "MazePoint" \
     -archivePath MazePoint.xcarchive \
     archive \
     CODE_SIGN_STYLE=Manual \
     CODE_SIGN_IDENTITY="Apple Distribution" \
     PROVISIONING_PROFILE_SPECIFIER="Your Profile Name" \
     DEVELOPMENT_TEAM=YOUR_TEAM_ID

3. Force Swift Library Linking: Manually supply Swift toolchain search paths during compilation:

   ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES=YES \
   LIBRARY_SEARCH_PATHS='$(inherited) $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME) $(SDKROOT)/usr/lib/swift'
