Toolchain Switching

New to Xcode 7.3 beta, you can select Preferences > Components > Toolchains without having to launch Xcode from the command line.

Things that you probably figured out on your own:

  • You can’t use beta toolchains for App Store compilations
  • The Playground is limited to the default toolchain. (And they’re still a bit laggy for massive playgrounds.)

Things you might not have thought of but are worth knowing:

  • The code migrator doesn’t work with beta toolchains. It’s strictly limited to the default toolchain.


  • This is awesome. I’m looking forward to develop jailbreak tweaks on Xcode’s IDE in the far future when the jailbreak dev toolchain can be used inside Xcode through this feature.

  • There’s also a new “two-link chain” icon (at first, I thought it was a paper clip) near the centre of the toolbar that provides quick access to the toolchains preference dialog.

  • So, does this mean I can safely use the beta and not install multiple versions of XCode?
