dsdump from shared cache?

[jslegendre]

Now that Big Sur is only shipping with a shared cache, it would be awesome to dsdump a framework from within the shared cache. Even support for extracted libraries would be sweet!

This would be very useful

I think this already works, e.g.

dsdump /System/Library/Frameworks/SwiftUI.framework/SwiftUI 

gives a valid list of symbols despite not being a valid path on the file system.

However, with --swift unfortunately it crashes, e.g

mh@MacBook-Air ~ % dsdump --swift /System/Library/Frameworks/SwiftUI.framework/SwiftUI 
zsh: segmentation fault  dsdump --swift /System/Library/Frameworks/SwiftUI.framework/SwiftU

mh@MacBook-Air ~ % dsdump
