Xcode – Install
Only install the Released version of Xcode, which as of the time of this writing is 12.4. Xcode 12.4 was released on January 26, 2021 and has been tested as compatible with building Loop.
Install Xcode from the App Store.
If Xcode 12.4 is not appearing for you in the App Store, it is possible you do not have the current OS installed. Catalina 10.15.7 is OK. Or you can update to Big Sur 11.1 if you prefer.
If you have the correct OS and you still are not being prompted to upgrade or install Xcode, it most likely means you previously had either a Beta version installed, or you installed a previous version from the Apple Developer web site. These instructions will help you get back to properly installing Xcode updates from the App Store: Fix-Xcode.
(Note, if you have less than 50 gig free, you should also use the Fix-Xcode link. Otherwise, if you see Xcode 12.4 in the Update list, continue with instructions on this page.)
- It is going to take more than a few minutes to download the Xcode update, so you need to disable your screen saver. Go to Settings / Desktop & Screen Saver / Hot Corners (bottom right) and set your top right corner to “Disable Screen Saver”. Then you can point your mouse to the top right corner to keep your screen saver from disrupting your download.
- Go to the App Store and download the most current version of Xcode.
- Follow the “Command Line Tools” and “Add Apple ID” instructions in Loopdocs Step 9.
- REBOOT (DO NOT SKIP THIS STEP).
- Go forth and build, or update, OR write a new popular iPhone game that will make you millions of dollars!
