*** Checking out MarkdownKit at "1.6"
*** Checking out SVProgressHUD at "2.2.5"
*** Building scheme "MarkdownKit" in MarkdownKit.xcworkspace
*** Building scheme "PocketSVG (iOS)" in Demos.xcworkspace
*** Building scheme "SVProgressHUD-Framework" in SVProgressHUD.xcodeproj

Actual outcome
carthage copy-frameworks fails with the following error message:

In attempt to read NSBundle «file:///Users/john/git/appsmono/ios/Apps/Calprotectin/Carthage/Build/iOS/PocketSVG.framework/»'s binary url, could not relativize «file:///Users/john/git/appsmono/ios/Carthage/Build/iOS/PocketSVG.framework/PocketSVG» against «file:///Users/john/git/appsmono/ios/Apps/Calprotectin/Carthage/Build/iOS/PocketSVG.framework/».

You can replace the framework with an arbitrary one. It does not solve the problem.

Expected outcome
Carthage should copy the frameworks correctly.

I could trace that back the problem to the changes in the current version. Rolling carthage version back to 0.36.0 fixes the problem.

0.36.0...0.36.1

We are using the recommended shell script since a few weeks and updated the contents with the ones in the Documentation/Xcode12Workaround.md. Did also not help! Caches were cleared accordingly and we also used a brand-new machine to simulate a build from scratch.
