Inside /Library/Developer/CoreSimulator I have 26GB (according to du -h) of old data that Xcode won't list under Window -> Devices & Simulators.
Because of Apples decision to not let even the root user write in this directory I am unable to delete them with rm -r * or put them in the trash etc.
The old runtimes are even listed in disk utility and can't be unmounted or delete from there - also due to missing permissions.
How can I get rid of this if even Xcode won't list them?
Also tried xcrun simctl delete all without success.
