Summary:
The issue sometimes appear when test changes the orientation of the simulator on CI Jenkins and try type text to UITextField. With error:
UI Testing Failure - Neither element nor any descendant has keyboard focus.

If I run test locally the test is successful but on Jenkins this issue appear sometimes. 
I found that this issue can be resolve if add additional tap on UITextField. I done this. 
After that I got error:

05:35:46     t =    15.61s         Wait for app to idle

I found that this is common issue but how to fix this decision is not present.

The example of code:

    XCUIElement *emailField = [[application descendantsMatchingType:XCUIElementTypeAny] objectForKeyedSubscript:EmailFieldID];
    
    [emailField tap];
    
    [emailField typeText:email];
