UIResponder Signal

Thread 1: signal SIGABRT means you are making a request for something that does not exist or is not well defined. It occurs, for example, when you do not properly connect the storyboard buttons with the code; When deleting modifies the name of a function associated with some element in the storyboard, but forget to undo the old link by the storyboard (it does not automatically detect changes, you have to delete them manually). Make sure nothing is happening.
