The way I do this is as follows    IBAction func pressButton sender  AnyObject        var disableMyButton   sender as  UIButton     disableMyButton enabled   false     The IBAction is connected to your button in the storyboard   If you have your button setup as an Outlet        IBOutlet weak var myButton  UIButton    Then you can access the enabled properties by using the   notation on the button name       myButton enabled   false

Let s say in Swift 4 you have a button set up for a segue as an IBAction like this  IBAction func nextLevel   sender  UIButton     and you have other actions occurring within your app  i e  a timer  gamePlay  etc    Rather than disabling the segue button  you might want to give your user the option to use that segue while the other actions are still occurring and WITHOUT CRASHING THE APP  Here s how   var appMode   0   IBAction func mySegue   sender  UIButton         if appMode    1       avoid crash if button pressed during other app actions and or conditions         let conflictingAction   sender as UIButton         conflictingAction isEnabled   false           Please note that you will likely have other conditions within if appMode    0 and or if appMode    1 that will still occur and NOT conflict with the mySegue button  Thus  AVOIDING A CRASH

You can enable disable a button using isEnabled or isUserInteractionEnabled property   The difference between two is     isEnabled is a property of UIControl  super class of UIButton  and it has visual effects  i e  grayed out  of enable disable  isUserInteractionEnabled is a property of UIView  super class of UIControl  and has no visual effect although but achieves the purpose   Usage    myButton isEnabled   false    Recommended approach  myButton isUserInteractionEnabled   false    Alternative approach

For those who Googled  disable a button  but may have more nuanced use cases   Disable with visual effect  As others have said  this will prevent the button from being pressed and the system will automatically make it look disabled   yourButton isEnabled   false    Disable without visual effect  Are you using a button in a case where it should look normal but not behave likes button by reacting to touches  Try this   yourButton userInteractionEnabled   false   Hide without disabling  This approach hides the button without disabling it  invisible but can still be tapped     yourButton alpha   0 0   Remove  This will remove the view entirely    yourButton removeFromSuperView     Tap something behind a button  Have two buttons stacked and you want the top button to temporarily act like it s not there  If you won t need the top button again  remove it  If you will need it again  try condensing its height or width to 0
