Mobile Build Systems, CI/CD, and Release Management Questions

Understanding mobile build systems in depth: Gradle for Android, Xcode for iOS, CocoaPods and SPM for dependencies. CI/CD pipelines specific to mobile: automated builds, unit tests, integration tests, code signing, app signing. Release management: versioning strategies (semantic versioning), beta testing on TestFlight/Google Play, staged rollouts, feature flags for gradual rollout. Build optimization for faster CI/CD cycles. Tools: Fastlane for automation, GitHub Actions/CircleCI for CI/CD.
