I'm learning Xcode development through apple's work book I got to lesson 1.9.
on Xcode I build an outlet that when the user clicks on its text changes.
this is what supposed to happen but when I excute the code I get this runtime error:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[interfaceBuilderBasics.ViewController pressButton:]: unrecognized selector sent to instance 0x104209070'
