Restore Xcode 7.3.1 after Xcode 8 upgrade

Question

Last night I went into my Application directory and renamed the Xcode.app to Xcode7.app

I then upgraded to Xcode 8 overnight.

When I came back in the morning, Xcode7.app was gone!! Nowhere to be found.

Now my project doesn't work on Xcode 8, upgrading to Swift 3.0 is impossible as many of my dependencies don't support it yet - and upgrading to swift 2.3 also doesn't work for some reason.

What happened to my Xcode 7 ? How do I get it back now?

Answer 1

I did not have this problem, and I also renamed Xcode (to Xcode-7.app) before updating.

I'm guessing it's because rather than choosing 'update' from the app store, I went to apple's downloads page and downloaded from there.

Try renaming your new Xcode to Xcode8.app, then go to https://developer.apple.com/download/more/ and download Xcode 7.3.1.dmg.
