Xcode 9: Block-compressed payload operation failed

Question

MacBook Pro El Capitan (10.11.6) here. I'm trying to install Xcode 9 so that I can play around with ARKit. From the Apple Developer's site, the only version of 9 I can find is Xcode_9_beta_6.xip (please correct me if I'm wrong!), so I download it:

Then I extract & run the XIP file:

But that operation fails due to this strange error that Google doesn't really help me out with (at all):

The operation couldn't be completed. Block-compressed payload operation failed

Any ideas what's going on here?

Answer 1

You must use at least the version 10.12.6 to install Xcode 9 beta 6 , I had the same problem but this solved after update my MacOs version, you can try unzip the file with Archive Utility.

Answer 2

xip -x Xcode_12.5_beta_2.xip worked for me today.
