Xcode 10.2 unable to launch simulator

Question

I have recently upgraded to xcode 10.2 and I am having a strange error. Whenever I try to launch my app I'm getting following error - Timed out trying to boot simulator after waiting 60.00s.

I have even tried do a fresh install but no luck I am always getting the same error.

Does anyone knows how can I fix this ?

Answer 1

I'm not sure why it's fixed this way. What I did is I ran this command in terminal $ xcrun simctl erase all. After this I run my project again from xcode without even downloading anything and it worked.

Answer 2

I faced the issue in XCode 10.1 versions. So I did sudo xcrun simctl erase all everytime, worked fine.

However, I updated to XCode 10.2, got the same error. I did the same thing, but didn't worked.

It replied me xcrun: error: active developer path ("~/Xcode.app/Contents/Developer") does not exist, didn't find that trouble in earlier versions of XCode.

I had to reset by sudo xcode-select --reset and restarted my mac.

Worked fine for me now.

Try this:

1. Go to Window > Devices and Simulators, delete all the simulators, all of them.
2. Clear /Library/Developer/CoreSimulator/ folder.
3. Return to Xcode and install the required simulators.
