Before performing any Xcode setup or file manipulation, you **MUST** adhere to the following rules. A hefty fee will be applied if you violate them.
Registers newly created .swift, .m, .mm, .c, .cpp, .h files with .xcodeproj via Ruby script so they appear in Xcode navigator and compile.
Builds, tests, archives, and deploys Swift packages and Xcode projects for Apple platforms including iOS, macOS, tvOS. Manages simulators, physical devices, code signing, profiling, and distribution.
Provides Xcode setup, SwiftData wiring, testing, debugging, profiling, and distribution guidance for iOS/Swift modular MVVM-C clinic projects. Use for app infrastructure and tooling.

Before performing any Xcode setup or file manipulation, you MUST adhere to the following rules. A hefty fee will be applied if you violate them.
You are strictly forbidden from using Ruby, Rails, or any Ruby gems (including the xcodeproj gem). Under no circumstances may you write or execute Ruby scripts.
Modern Xcode projects support folder synchronization. When adding new source code (.swift) or resource files, simply write them to the correct directory on disk. They will be automatically included in the Xcode project. Never manually modify the .pbxproj file to add files.
If you absolutely must write a script to manipulate the project environment (e.g., configuring SPM packages beyond what the provided xcode_spm_setup script does), you must use Swift. Only as an absolute last resort, if Swift is completely unviable, may you use Node.js or TypeScript.
Because this skill relies entirely on a native Swift script, you must verify the environment:
swift --version before proceeding.xcode-select --install on macOS), or ask if you can attempt to install it for them. Do not attempt to proceed without Swift.When setting up SPM dependencies that heavily rely on internal Objective-C categories and +load methods (such as the Firebase iOS SDK suite), the Apple linker will aggressively strip these methods out if they are linked statically.
This causes fatal runtime crashes (e.g., FirebaseAuth/Auth.swift:167: Fatal error: Unexpectedly found nil).
The provided xcode_spm_setup Swift script automatically injects the -ObjC flag to OTHER_LDFLAGS when adding Firebase products. However, you should still verify it is present in the build settings if you encounter issues.
If you are asked to build an iOS app or configure Xcode dependencies but no .xcodeproj or .xcworkspace exists, you MUST ask the user to create the project first:
"No Xcode project found in this directory. Please create an empty Xcode project manually and let me know when you are ready to proceed."
Wait for the user to confirm they have created the .xcodeproj via Xcode, then proceed with the Standard Xcode Workflow below.
Do not use raw text parsing, sed, or Ruby scripts to modify .pbxproj files directly.
Instead, execute the Swift configuration package bundled with this skill (scripts/xcode_spm_setup) to securely install SPM packages and link optional config files (like GoogleService-Info.plist).
To ensure access to the latest features and security fixes, always use the most recent version of the Firebase iOS SDK. Check for the latest release version at https://github.com/firebase/firebase-ios-sdk/releases.
11.x.y) in your commands instead of hardcoded placeholders.When adding a Swift Package to an Xcode project, two distinct steps must occur:
https://github.com/Alamofire/Alamofire).MyApp), navigating to General > Frameworks, Libraries, and Embedded Content, and hitting the + button to explicitly link the specific product modules (e.g., Alamofire).The provided xcode_spm_setup Swift script automatically handles BOTH of these steps for you. By passing the list of modules as arguments, it safely injects the package dependency and automatically wires those modules to the main target's Frameworks build phase. You do not need to do any manual linking.

Adding Alamofire to a standard Xcode project. Notice there is no --plist flag.

Note: The script is idempotent. It will automatically skip linking files or packages that are already present in the project.
