Hello,
I'm unable to run any test cases in Xcode 16 with the iOS 18 simulator.
Steps to Reproduce:
Environment:
xcrun simctl delete all
This resolved the issue. However, you need to manually add all the simulators after this.
I would suggest not deleting simulator devices to workaround this issue. If there is something bad about the device state, I'd prefer to triage that to figure out what is going wrong. Could you collect a sysdiagnose and simctl diagnose when in this state and file a feedback report?

Hello, I have exactly the same issue. Xcode 16, macOS sequoia 15.0.1, simulator iOS 18.
Do you have a suggested solution?
I am having the same issue with Xcode 16. Tests would run in any device with iOS 17 but not in any device with iOS 18.
I ran: xcrun simctl delete all and manually installed two simulators, one with iOS 17.0 and one with iOS 18.0. At first neither would work and was stuck on testing... but after restarting my computer the iOS 17 simulator works and the iOS 18 simulator still just says testing...
xcrun simctl erase all solved the issue for me
I'm having this issue too but the solution didn't work for me.
Any news on this issue? Current solution written didn't worked for me :/
In my case, removing and redownloading the simulator did not help either. I discovered that the issue was caused by an outdated version of Dynatrace library. After some investigation, I found that such issues often occur when a new version of Xcode is released (this happened with Xcode 15 and earlier versions as well). I recommend checking your project dependencies to ensure they are up to date.
