When I try and run my app on my phone (iPhone 14 iOS version 17.5.1) in XCode 15.4 I get the following:

Previous preparation error: The developer disk image could not be mounted on this device.. You don’t have permission to save the file “DADFD0D2-1ED9-4F56-AAAE-310E8BF60870” in the folder “CoreDevice_DDI_Staging_503”.

Haven't been able to figure out the root cause. Any advice would be appreciated.

Can you run this command in Terminal, and let me know the results?

sudo chmod 0777 /private/var/tmp

It did help me too! thank you so much, they are so many topics about this issue on forums ! You should promote this post at top level !

this way we could avoid doing stupid things like : deleting /library/Developer/DeveloperDiskImages as it's "claimed" to be fixing the pb which it is not actualy
