When I try to open the Xcode Documentation inside Xcode 12 (downloaded from the app store), the whole app closes. Is anyone else seeing this

This affects Xcode 12 when downloaded from the Mac App Store. We're aware of the problem and we're working on a fix.

As a workaround in the meantime, documentation is available on developer.apple.com, or if necessary, Xcode 12 can be downloaded from the More Downloads area. After the next Xcode update, re-download Xcode from the Mac App Store to enable automatic updates, with smaller download sizes.

Same problem (xCode from AppStore)

Had the same Xcode 12 Documentation crash. Now upon downloading the Xcode_12.xip file from Apple downloads, and double-clicking it to expand it on macOS Catalina, I get the following Archive Utility error after stalling for a while about half-way through the decompression: "The operation couldn't be completed. Block-compressed payload operation failed."

What can I do about that? The man page for xip in Terminal doesn't help.

Looks like 12.0.1 is now in the Mac App Store to address this very issue.

Have downloaded/installed Xcode 12.0.1 from Mac App Store. Now, when opening the 'Developer Documentation' window, instead of showing documentation in that window, Safari gets launched showing info from developer.apple.com. Big change! Is this intended/expected behavior?

Xcode 12.0.1 from the App Store fixed this problem; Developer Documentation window now works. Thank you!
