Xcode - How to fix 'NSUnknownKeyException', reason: … this class is not key value coding-compliant for the key X" error?
(79 answers)
Closed 6 years ago.
For some reason when I run my app , the app crashes then in Xcode it takes me to app delegate. The error message is given to me at the top(where "the class AppDelegate: UIResponder, UIApplicationDelegate" is). The error message is "Thread 1: Signal SIGABRT". As I am only a novice in programming, I have no idea what this means, and have found no help online. Here are screenshots of what I get in Xcode. This is not the duplicate of the other problem, because my problem was why Xcode takes me to app delegate and shows me the SIGABRT ERROR. I just didn't know what I was supposed to do after that.FYI-I did not know in the console errors pop up there
This is what is my console:

I'm quite new to Xcode and Swift and in many of my previous projects I kept getting a Thread 1: signal SIGABRT error. I can't discern what the problem is from the error report. Can someone help find the source of the error itself. This is the error report:

The crucial information is:
[UIViewController setValue:forKey:] this class is not key value coding-compliant for the key test.
[UIRuntimeOutletConnection connect]
That leads to a dead connection in Interface Builder
Press ⇧⌘F
Type test and return
Go thru the search results and select the one pointing to Interface Builder.
Disconnect the dead outlet.

Check if your stepper has a redundant outlet in your storyboard. Right click on the stepper object in Storyboard and check if there is any outlet you don't want.
Also. Remove #Iboutlet var textV:UILabel! or reconnect it with the Label in your storyboard and the error will be gone.

I have looked at other questions asked but none of these solutions work. Does anyone have any idea from the errors listed as to why it isn't working?
Thanks
The problem described in your error is due to a incorrect linked class in your storyboard or nib.
You have an incorrect link. Probably you delete or changed name.
Check if your IBOutlet are correct link as image:
and remove invalid links.

If possible please explain fix visually as I am programming retarded :-)
Further to Hayden's answer - you can easily check to see if any IBOutlets which you think should be connected to your View Controller are actually not connected by looking at the margin in Xcode (as below). Each IBOutlet will display a filled in circle showing you that it's connected to an element on the storyboard.
If the circle is empty it's not connected which can cause a crash...
