问题
After updating from macOS High Sierra to Mojave and I successfully installed Xcode 7.3.1 but it cannot be opened. Does Mojave support Xcode 7?

I have experienced the same issue after upgrading to macOS Mojave. The only solution which I had to do is to download Xcode 8 and migrate to Swift 3.
Incase there're any alternatives, please share!
