The models' case: Assuming an Apple-first team without dedicated CI staff, its first-party Xcode, signing, parallel testing, TestFlight, and App Store Connect integration offers the least. The models' main caveat: Its Apple-only workflow is not for teams wanting one highly customizable pipeline across iOS and Android. The strongest alternative is Codemagic — Version-controlled YAML, managed iOS signing, fast M2/M4 runners, and zero-base-cost pay-as-you-go pricing make it exceptional value. Not unanimous: Claude picks fastlane; Gemini picks fastlane.
