What's the error you're getting?

[Justin]

Invalid device state for iPhone X simulator

[basher]

I have a suspicion that Xcode 10.3 started requiring you to boot the sim before running spawn. you can get around this though by using spawn -s, which skips the booting part

[basher]

Should work as long as you don't use any APIs (unsure what those are) that require the sim to be booted

[Justin]

I’ll try that thanks @basher
