I want to install and try out the new features of macOS 10.12. Also I really want to work on Xcode 8.0. But the same time I have some client projects which should written on Swift 2.2 [ Xcode 7.3.1 ], I don't want use Swift 2.3 or Swift 3.0.

So is it possible to install Xcode 7.3.1 in macOS 10.12? Is there any hacky way to do this?

Yes I have successfully installed both Xcode 7.3.1 and Xcode 8.0 in my macOS Sierra.

Now using both Xcodes. But whenever I run my project using Xcode 7.3.1 I am getting this error DTAssetProviderService could not start DTXConnection with Simulator 'iPhone 6s'. Check the system log for errors. I don't know the actual reason for this. I have googled for the answers but those suggestions didn't help me. But at the same time I can run projects in Xcode 8.0 in Simulator, no errors, nothing.

If anyone came to see this, Please let me know your comment.

You can absolutely install Xcode 7.3.1 on macOS Sierra alongside the beta version of Xcode 8.

If you are having issues running Xcode 7.3.x or running the simulator:

  1. Reinstall Xcode 7.3.x from https://developer.apple.com/downloads/.

  2. Manually attach the debugger to your process as outlined in this Stack Overflow answer.
