When I open the "devices and simulators" window now I only see "No selection" in the center. No sidebar pane, and no detail pane. I was able to set up some simulators up to last week or so, and now this. I've no idea how to create a new simulator or inspect the ones I have.
Workaround: Perform this command in Terminal...
defaults delete com.apple.dt.Xcode
Thanks for the Workaround.
Count me in with Xcode Version 16.0. Could not find another article on this subject. What is the Best Practice to help get this fixed with Apple Computer.
