It will shows a dialog when I launch Xcode.app.
You don’t have permission to save the file “DeveloperDiskImages” in the folder “Developer”.
Then, I clicked OK to move on. Then, I choose the button "Create New Project", the app just crashed immediately. I also tried to manually create the folder "DeveloperDiskImages" in /Users/howardchung/Library/Developer/
It will not show the dialog while launching Xcode.app, but also crashed in "Create New Project".
What version of Xcode is this with?
It sounds like you have a permission issue with ~/Library/Developer that prevented you from creating that directory and installing the DDIs there.
Note that Xcode 15.x used ~/Library/Developer where as Xcode 16 now uses the system location exclusively (/Library/Developer/...). This directory permission issue probably won't impact Xcode 16, but you should still look into it and fix the permissions since other services might need to utilize that path.
