Are you sure you have a UIView  or subclass  assigned to the  view  property of yourViewController     Right click on  File Owner  in the left pane of the xib for yourViewController and verify that the  view  outlet is set  If not  set it to a view     this will definetly fix the Issue

I ran into this problem in a slightly different way from the other answers here   If I simply created a new xib file  added a UIViewController to it in Interface Builder  and set that UIViewController s custom class to my view controller  that resulted in the  view outlet was not set  crash  The other solutions here say to control-drag the view outlet to the View  but for me the view outlet was greyed out and I couldn t control-drag it     I figured out that my mistake was in adding a UIViewController in Interface Builder  Instead  I had to add a UIView  and set the Custom Class of the File s Owner to my view controller  Then I could control-drag the view outlet of the File s Owner to my new view UIView and everything worked as it should

You guys are right  but as I m a newcomer it took me a little while to figure out all the steps to do that  Here s what worked for me   Open the XIB file causing problems Click on file s owner icon on the left bar  top one  looks like a yellow outlined box  If you don t see the right-hand sidebar  click on the third icon above  quot view quot  in your toolbar  This will show the right-hand sidebar In the right-hand sidebar  click on the fourth tab--the one that looks a bit like a newspaper Under  quot Custom Class quot  at the top  make sure Class is the name of the ViewController that should correspond to this view  If not  enter it In the right-hand sidebar  click on the last tab--the one that looks like a circle with an arrow in it You should see  quot outlets quot  with  quot view quot  under it  Drag the circle next to it over to the  quot view quot  icon on the left bar  bottom one  looks like a white square with a thick gray outline Save the xib and re-run

I just fixed this in mine  Large project  two files  One was  ReallyLargeNameView  and another was  ReallyLargeNameViewController   Based on the 2nd answer chosen above  I decided I should clean my build  Nada  but I was still suspect of XCode  as I have two identical classes  should abstract them but eh     So one s working  one s not  File s owner names are so far as copy and pasted  outlets rehooked up  xCode rebooted  still nothing   So I delete the similar named class  which is a view   Soon  new error  outlet inside not hooked up  literally was  webView not key value  blah    basically saying  Visual Studio s better   Anyway    I erase the smaller named file  and bam  it works   XCode is confused by similar-named files  And the project is large enough to need rebooting a bit  that may be part of it   Wish I had a more technical answer than  XCode is confused   but well  xCode gets confused a lot at this point  Unconfused it the same way I d help a little kid  It works now     Should benefit others if the above doesn t fix anything   Always remember to clean your builds  by deleting off the simulator too

My issue with this was caused by having a duplicate nib in the class folder that did not have the view set  xcode seemed to be choosing one nib for a build and then the other the next time I built the project  Just deleted the other one  Looks good  Doh

For me  the problem was caused by calling initWithNibName bundle    I am using table view cells from a nib file to define entry forms that sit on tableViews   As I don t have a view  doesn t make sense to hook to one   Instead  if I call the initWithStyle  method instead  and from within there  I load the nib file  then things work as expected

If you re using a custom init method  check that you re returning something valid  I ran into a piece of code that crashed on something like this   -  id init      self    super init      if  self          CustomController  controller     NSBundle mainBundle  loadNibNamed NSStringFromClass className  owner self options nil        return self      In another class  the controller was created like so   CustomController  controller     CustomController alloc  init     The problem is that in the init method  self hasn t changed and should look like this instead   -  id init      self    super init      if  self          CustomController  controller     NSBundle mainBundle  loadNibNamed NSStringFromClass className  owner self options nil          controller viewDidLoad         self   controller       return self

I ran into something very similar tonight  with a Swift UIViewController subclass  In this case  none of the above fixes worked  but reordering my code a bit did  Net-net  having an extension to the subclass occur before the subclass s definition itself in the same file seems to confuse XCode  despite compiling fine  the fix was to place the extensions after the subclass s definition   I ve posted the details in an answer to this similar question

If you have tried everything and you still get this error  try re-creating the class file from scratch but remember to select the  Also create XIB file  check box  This will auto link up a few items that are not linked when creating these files separately  After this is created  you can likely cut and paste everything onto the new XIB and it should work fine   I am finding this issue specifically with creating files separately in Swift

I d like to second Stephen J  Some times X Code does just get confused  I just had an experience where I had played around with the UI a lot  and had added and deleted outlets quite a few times  The outlets just would not wire-up any more  I never did figure out a specific reason  I had tried all the solutions above   and I just had to delete the NIB and recreate it from scratch  and in fact had to use a different name for the NIB before it would work   XCode 4 6 1  Wasted a couple of hours on that

For me all the things stated here https   stackoverflow com a 6395750 939501 were true but still it was throwing error  reason was I created a View class with name ABCView and then deleted it later I added a view controller as ABCViewController so somehow it was referring to old ABCView in new view controller  I had to delete the ABCViewController and add a new one with different name that solved my issue   Thanks

I had the same problem  but a slightly different solution was called for  The problem in this case was the class of the File Owner  rather than the class of the View  To set this  I had to click the  backwards play  icon in the lower left corner of the Interface Builder window  and options then appeared that isolated the characteristics of the File Owner  the First Responder  and the View  Clicking on the first one  a large transparent box   enabled me to then set its custom class as suggested above

The previous answers almost solved the problem for me  but the last step was missing    Create a xib and swift file with the same name       Set the file owner to be the UIView subclass       Drag an outlet from the View to the UIView subclass  name it  contentView       Add this custom initializer so when the xib loads it attaches the contentView     required init  coder aDecoder  NSCoder            super init coder  aDecoder          Bundle for  self classForCoder  loadNibNamed  SampleView   owner  self  options  nil          addSubview contentView          contentView frame   self bounds         contentView autoresizingMask     flexibleHeight   flexibleWidth           Now any  IBOutlets you add will be attached   Cheers  Richard

Just had the same error in my project  but different reason   In my case I had an IBOutlet setup with the name  View  in my custom UITableViewController class   I knew  view  was special because that is a member of the base class  but I didn t think View  different case  would also be a problem   I guess some areas of Cocoa are not case-sensitive  and probably loading a xib is one of those areas   So I just renamed it to DefaultView and all is good now

I had the same issue with XCode 4 6 3  I had started out with a couple files named MySettingsView h and  m but deleted them in favor of MySettingsViewController h  but despite trying most of the hints mentioned here  it still kept erroring with       2013-07-05 11 48 17 205 MyApp 39024 c07      Terminating app due to uncaught exception  NSInternalInconsistencyException   reason     - UIViewController  loadViewFromNibNamed bundle   loaded the    MySettingsView  nib but the view outlet was not set     It was evidently still  confused   trying to load MySettingsView xib instead of MySettingsView Controller xib  Maybe its  do what I mean  logic is too fancy   So I worked around the problem by hardcoding the NIB XIB name in MySettingsViewController m   -  id initWithNibName  NSString   nibNameOrNil bundle  NSBundle   nibBundleOrNil       self    super initWithNibName   MySettingsViewController  bundle nibBundleOrNil
