AwaitKit causes unit tests to fail

Open t3ddyK opened this issue 6 years ago • 1 comments

I've have installed AwaitKit in a project, however have not started to implement it. The addition of it however has now started my Unit Test's to fail with -

The only way around this for now is to disable the main thread checker in my test scheme, which I'd rather not do. I'm a little confused as to why this is happening and how to fix it.

It looks like based on the call stack OAuthKit is using a UIViewController, perhaps make sure when work is being done by OAuthKit (It's probably trying to bring up view for OAuth) that you call those functions on the main thread.
