Yet another possible cause   In my case  I had a xib and was calling Bundle main loadNibNamed     at which point it was crashing  All my IBOutlets and IBActions seemed fine  In the end I noticed that the nib was actually loading  but then when I tried to access the first  and only  view  nib first   that was not working  In fact nib count was returning a very large integer  max int    instead of the expected 1  I tried re-adding the view  but still no luck   In the end  I deleted the whole xib file and started again  but I kept some of the views in my clipboard so I can paste them instead of recreating them again    This worked

For Swift 2 3  This seems to be a bug with Xcode 8 and Swift 2 3  if you re connecting the button action to your code via storyboard be sure that Xcode didn t rename the action  for me it s adding a withSender  at the end of the methods  so what I do is going to my code and renaming the method to match the one Xcode wrote   For any other version check the correct answer

In my case  I was calling a delegate method but the method wasn t declared   This error is generic and can appear by a number of reasons  Make sure you have not disabled your Logs to actually see what happened  Enable OS ACTIVITY MODE in the schemes if you have disabled it  You might have disabled it to prevent a lot of irrelevant logs but they are handy   You can also trace the cause in more details by adding an exception breakpoint po  arg1  As already mentioned by Ahmed-Lotfi  Here is a common checklist that you can go through   2  Check if you have renamed an IBOutlet and calling it 3  Check if you have renamed a method name or the method doesn t exist 4  Check if you are trying to add or remove any view from hierarchy 5  Check for any missing framework or library 6  Check if you   ve forgot to register your custom cell identifier 7  Check for any missing flag in the Proejct Setting  -obj  or any other linker flag etc

Other solutions didn t work form me  here s mine  It applies only to Xcode 8 when running in Swift 2 3 legacy mode   Looks like Interface Builder is trying to rename the method that should be hooked up to the button   Here s a radar with more details   The solution  workaround  is to manually replace the method parameter name to      IBAction func editPictureTapped sender  UIButton        not working     print  Tapped       Change to this    IBAction func editPictureTapped    UIButton           working OK     print  Tapped

Make sure you are not dynamically applying relative constraints to a view which is not yet there in view hierarchy   UIView  bottomView     UIView alloc  initWithFrame CGRectZero    self view addSubview bottomView    bottomConstraint    NSLayoutConstraint constraintWithItem bottomView                                                 attribute NSLayoutAttributeBottom                                                 relatedBy NSLayoutRelationEqual                                                    toItem self view                                                 attribute NSLayoutAttributeBottom                                                multiplier 1                                                  constant 0   bottomConstraint active   YES    In above example  bottomView has been made part of view hierarchy before applying relative constraints on it

CMYR -  his could also happen if you ve wired up a button to an IBAction that doesn t exist anymore  or has been renamed    If you re running into this problem make sure that you go to Main storyboard  RIGHT click on the yellow box icon  view controller  at the top of the phone outline and DELETE the outlet s  with yellow flags    What happens in instances like this is you probably named an action  then renamed it  You need to delete the old name and if that was the only issue will start right up in sim
