I am facing issues with XCode snapshot. Actually I have Xcode 8.3.3, but I need to run Swift 4 project on it. Upgrading OSX and Xcode version is not an option for me.

I followed the accepted answer from here: Is it possible to compile Swift 4 on Xcode 8.x?

I downloaded Xcode snapshot (latest, 30th Dec release of toolchain) from https://swift.org/download/#snapshots

and made the required settings of toolchain. However, I am encountering a strange issue.

Again, to resolve this, I tried the accepted answer on link Could not build Objective-C module '_SwiftUIKitOverlayShims'

however, even this does not seem to work. Please suggest where I am going wrong.

  • What is the reason you can't upgrade? Because, to be completely honest, your best option really is to upgrade Xcode. – JeremyP Jan 03 '18 at 09:38
  • My Mac has a 4GB RAM and it is already very slow. Upgrading it to High Sierra and installing Xcode 9.2 will kill it totally..! That is why Im desperately looking for a workaround – Shradha Jan 03 '18 at 09:41
  • I assume this is just to try Swift 4 out as you will never be able to submit an app using this method. – Upholder Of Truth Jan 03 '18 at 10:16
