If you accidentally upgraded to Xcode 8 and wish to get to Xcode 7 that can run in parallel, you can follow similar steps:
#Revert to xcode 10.3 install
Install an older version of macOS on a virtual machine and install Xcode 10.3 on that virtual machine if you need to use Xcode 10.3. Apple is not going to fix Xcode 10 bugs now that Xcode 12 is out. Xcode 8 has a backwards compatible Swift 2.3 version, but there are still some minor changes (i.e. Xcode 10 is not officially supported on Big Sur. Open the terminal and create a symbolic link from Xcode 8 Developer Disk Image 10.0 to Xcode 8 Developerĭisk Image folder using this command: sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/atform/DeviceSupport/10.0 (14A345 )/ /Applications/Xcode7.app/Contents/Developer/Platforms/atform/DeviceSupport/10.0 There are two updates, which will likely take about 2 hours to download.
