Pseudo Terminal Setup Error when running iOS Simulator

Question

I tried to execute my app in the iOS Simulator. The build succeeded, but I got an alert with an error message before running and the app did not execute:

Pseudo Terminal Setup Error
ErrorCode: 1 Errno: 6

What is this and how can I fix this?

Answer 1

Just restart Xcode and run your app again.

A pseudo terminal is an emulated terminal which is controlled by a master application, in this case, Xcode. For some reason, it encountered an error while trying to run that emulated terminal.

A common problem that can cause this is that you tried to run an instance of an iOS application too quickly after stopping another instance.

Answer 2

How to resolve the error:

1. Quit the simulator
2. Restart Xcode - (Make sure that you have saved /committed any changes you have made to your code)

Answer 3

I can't post comment, that is why I wrote here. To those for who this issue repeats even after restarting Xcode, remember to kill process at all, don't just close the project.
