i have both x code 7.3.1 and x code 8 installed on OS X 10.11 and i need them both to manage my apps written with swift language.

i have downloaded both from apple website (not from app store) and i still keep the setup files (.dmg & .xip)

will xcode 7.3.1 still work on sierra if i upgrade?

thanks in advance.


Yes it works. I have macOS Sierra with Xcode 7.3.1.


  • Simulators
  • Debug on device
  • Validate/Upload to store
  • CocoaPods
  • thanks for your answer. is it fully functional after update? i heard that the simulator stops working Sep 22 '16 at 4:58

  • @RobinThuranMalhotra I do not know for Carthage. I installed macOS Sierra GM seed a few days before the release and I was surprised how well it worked. There was one documented issue for homebrew (and easy to fix) and a very specific issue with a custom keyboard layout I use. I do not see any issue on Carthage's Hub about macOS Sierra.

    @neobie, at this point it is not Sierra that will prevent you to release to iOS 6 but when Apple will decide it otherwise.
