Error in the app at launching a phone call

Question

I'm working on a app in which you can make an phone call after touch the label with the number. But at the moment in which the phone call is done, the Xcode Log shows me a log of error with the constraints..

I thought that was because the custom navigation controller on my app, but even with de default nav controller shows me the log.

I don't know what I should do and where is the error. Even with this Storyboards shown below, the log remains..

Story with custom nav controller

Story with default nav controller

This is the log..

Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "", "", "" ) Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in may also be helpful. 2016-05-18 17:11:25.093 App[742:295497] Unable to simultaneously satisfy constraints.

Thanks in advance!

Check every connection from de UI builder to the code. That's always the case for my when that happens.
