What’s Changed

  • Auto-wrap xcodebuild invocations via bitrise-build-cache react-native run when React Native build cache is active on the machine. The xcodebuild calls inside this step become children of the active RN parent invocation. Killswitch: BITRISE_BUILD_CACHE_RN_WRAP=0. (#83)
  • Remove sliceutils dependency. (#80)
