This version includes the SDKs for iOS 14, iPadOS 14, macOS Catalina, tvOS 14, and watchOS 7. Download from the Mac App Store.
Search for Xcode in the Mac App Store do a fresh install of Xcode. (The button in the Xcode page in the Mac App Store will say 'install' instead of 'update' because you removed Xcode in step 2.).
XCode won't update from App Store. Ask Question Asked 4 years, 9 months ago. I tried to delete the app and download it from the App Store again, but it all ends with Xcode.appdownload file being downloaded and that's it. The Mac App Store is broken beyond repair. You can try to reload the update page using CMD-R. That helps sometimes.
I updated one of my devices to iOS 9.2.1 and in order to build I have to update my Xcode version as well.
I tried downloading it twice from the Mac Store, but each time at about 60-70% I get a message that the download failed and I should try again.
