  • Xcode build duration defaults write com.apple.dt.Xcode ShowBuildOperationDuration -bool YES
  • Faster build times by leveraging multi-core CPU defaults write com.apple.dt.Xcode IDEBuildOperationMaxNumberOfConcurrentCompileTasks `sysctl -n hw.ncpu`
  • Flag to emit warnings whenever a function takes longer than some threshold to compile. Add the following to Other Swift Flags
    • -Xfrontend -warn-long-function-bodies=100, where 100 is the number of milliseconds you’d like the warning threshold to be
  • To enable warn about individual expressions that take a long time to type check, go the Build Settings, “Swift Compiler - Custom Flags”, “Other Swift Flags”, and add:
    • -Xfrontend -warn-long-expression-type-checking=<limit> where <limit> is the lower limit of the number of milliseconds that an expression must take to type check in order for the warning to be emitted.
