UI Automation Error: UI Authentication Error - APP failed to complete within 30.0 s

Question

Since the xCode update, I had a problem running any test ui example. This gives me this error when it is expected to be executed with a simple click:

 XCUIApplication *app = [[XCUIApplication alloc] init];
  XCUIElement *passwordSecureTextField = app.secureTextFields[@"Password"];
  [passwordSecureTextField tap];

Anyone have any ideas why I am getting this error? I searched on google and here, but did not find any solutions.

Thanks.

" quiesce", t = 18.90s -, UIProgressView. ( "quiesced" ).

("quiesce" as a word is not in my active dictionary, which, of course, delayed my understanding of what was going on. A console exit pushed me in the right direction. I would put more bells on "idle" than quiesce for many developers.)
