Unknown class info in Interface Builder file.

Every time I run my Project some crazy bugs will appear or some bars disappear. Did anyone know what to do?


Try this, in order:

  1. Product->Clean in Xcode
  2. Delete the app from the simulator or device
  3. Restart Xcode
  4. (Build &) Run again

If this doesn't help, you likely have a reference to a class in the nib or storyboard that you have to manually find and remove.

Xcode 6 Bug: Unknown class in Interface Builder file, You just have to open the interface builder, go to Identity Inspector of ViewController that had its class renamed, select class and press Enter. That will reassign renamed class to selected ViewController and also reset Module Value which gets lost after renaming the class.

The warning may be because you have assigned a removed/deleted custom class name for one of the UIView subclass. In order to fix such scenarios,

Open interface builder class as Source Code by right clicking on it (Open As -> Source Code).
Find your unknown class name in the source file. And handle accordingly.

It worked for me.

Unknown class in interface builder, bundle file (such as for a framework/static library) that gets copied to a different target, you'll want to set an explicit module target for each xib/� This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

I did run into this problem today using Swift.

I changed a class Model.h + Model.m to a Model.swift. This object was used in Interface Builder with the class = Model.

As soon as I replaced the object the class could no longer be loaded.

What I had to do was to change the class reference in IB from:

Class = Model
Module = 

to

Class = Model
Module = <TARGETNAME>

You'll find the <TARGETNAME> in the build settings. It is also the name that shows up in your generated Swift-Header: #import "TARGETNAME-Swift.h"
