I spend a hour finding out what was wrong   But Clean Project did the trick    Build - gt  Clean All   The accepted solution is probably also working   but this was enough for me

Also make sure that the XIB-file is included in your target  Check the file inspector when the XIB-file is selected  first tab on the right  in the middle there is section  target membership   The target you build for must be checked  otherwise the XIB-file won t be included

Note that if you are using  self class  nibName  can return different name if you are using swift    might be different than the name you are expecting it to return   Especially if you have multiple targets for your code   In that case try to override   override var nibName  String           return  YourXibFileName     No  xib at the end

This can also occur if you change the name of your xib file  and you forget to change all the places it is referenced   Example  MainWindow xib is a TabBarController that contains a custom ViewController named FirstViewController with associated xib file FirstView  You change the name to SecondViewController and associated xib file to SecondView   Solution   Open MainWindow xib  that contains the TabBarController     Select the tab that is for the ViewController you changed  On the Identity inspector  Change the Custom Class name to SecondViewController  On the attributes inspector  Change the xib name to SecondView    Open SecondView xib  this was copied from FirstView xib     On the Identity Inspector  change the custom class to SecondViewController    Optionally you may need to    Right click SecondView xib  verify that  Identity and Type- Target Membership  is enabled  Make sure  Build Phases -  Copy Bundle Resources  shows your SecondView xib I also found I occasionally needed to build clean and delete the app from the simulator to get the xib file to actually update  The simulator has an internal cache for xib files that is a little inconsistent

I have faced this error a lot of time  also research why this error occurs and finally  I caught this error  this error a silly error which occurs when we misspelled  xib file name   NSArray  nib     NSBundle mainBundle  loadNibNamed   TableViewCell  owner self options nil     At this point  I misspelled  TableViewCell as TabelViewCell   because the perception of some time we read it as correct  this is the most common problem  Just copy your  xib file name  and paste it

Simply try removing the   xib  from the nib name in  initWithNibName    According to the documentation  the   xib  is assumed and shouldn t be used

I had renamed a xib and had this problem  the solution for me was to edit the main window xib manually and change the offending text  search for the offending xib name in the relevant xib   view as source code   changed   lt viewController nibName  OldNibName  id  116  customClass  SomeViewController  gt    with   lt viewController nibName  NewNibName  id  116  customClass  SomeViewController  gt    and it worked

User · Answer

This error can occur when you rename files outside of XCode  To solve it you can just remove the files from your project  Right Click - Delete and   Remove Reference     Then after you can re-import the files in your project and everything will be OK

I tried several things  finally what worked for me was to delete  and move to trash  the  xib file in question   Then re-create it   To make things easier  I copied the stuff in the  xib temporarily to another  xib  then copied it back into the newly created one

In my case  this happen because of I deleted the Main storyboard and in general tab Main Interface property cleared and added custom one as Start  After I Change the Main Interface to Start storyboard except Start it s working

For me   I did not install that nib in required target   Step 1  Click on your nib in Project Navigator  i e  In First left tab   Step 2  Go to File Inspector  i e  In First right tab   Step 3  Go to Target membership and tick on target in which you want to use your nib

I was setting an optional self collectionView  backgroundColor in the init coder  constructor of my collection vc   Once I will have moved that setup in viewDidLoad the exception had somehow disappeared  puzzling

User · Answer

Well  I think the error says that it can t find a nib file named  RootViewController  in your project     You are writing these lines of code    self viewController     RootViewController alloc       initWithNibName   RootViewController iPhone xib  bundle nil    self viewController     RootViewController alloc  initWithNibName   RootViewController iPad xib  bundle nil     At the same time you are asking it to load a nib file named  RootviewController      Where is it    Do you have a xib file named  Rootviewcontroller

I was getting this error when I was trying to add gestureRecognizer to my ViewController s view and the target was view  instead of being self   Instead of   self view addGestureRecognizer UITapGestureRecognizer target  self view  action   selector handleTap          Fixed to   self view addGestureRecognizer UITapGestureRecognizer target  self  action   selector handleTap          And the error was gone

In Identity inspector change class name with the corresponding identifier and also In Attributes inspector modify Indentifier then it should work as expected

User · Answer

There are so many reasons for this error I also got one and solved it   It may be possible that you are adding a third party framework and not including it in the Copy Bundle Resources That solved the problem for me   Do this as follows  Go to Target -  BuildPhases -  CopyBundleResources -  Drag and drop your framework and run the code

User · Answer

I ve got some subprojects   I solved this problem via adding xib file to Copy Bundle Resources build phase of main project

User · Answer

You can check file xib is same name with your file class  Default XCode will get name xib file from name file class  so if their names are different  XCode can t detect from storyboard It s work with me

User · Answer

I ve gone through the same issue quite a number of times  What I ve found for myself is that the xib file i m linking would always be misspelled   In my case  this is the line of code for me that lead to the exception    NSArray nib     NSBundle mainBundle  loadNibNamed   shelfcell  owner self options nil    The  shelfcell  was my xib file name  But i had mis spelled it as  ShelfCell    shelfCell  etc  which lead to the exception  So dont bug your head much  Check the lines of code and the spellings  Thank you
