Can't update Xcode 11 [closed]
Manual download
The always working and preferred workaround!
Download directly from Apple:
- Latest Release version or
- Latest Beta version or
- Any version you need and all other downloadable contents
Then extract and move it where you like. This has so many benefits comparing to AppStore updates. (like the ability to resume download, not replacing the old one, not wasting hidden directories and etc.)
Note that you should use safari to download it.
Force App Store to re-download.
Apple suggested this workaround but many developers (including me)prefer manual download to save a lot of network traffic!
