An app I recently started and working its keeps crashing with a SIGABRT message. The general message at the top of the debugger says:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIView 0xb651580> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key parentEmail.'
... At the the bottom it says:
libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)
Let me know if the "first throw call stack" info is necessary to solve this one.
Check and make sure that you didnt previously have a button/text field/label previously linked with an action, then deleted that item. The link still exists. Check and make sure that all your links match to existing items.
Usually this comes from an outlet link inside a xib with no corresponding class variable.
Did you remove a variable from a class without removing the link inside the xib?

I am facing an NSUnknownKeyException for a back button present on a Storyboard, i.e. FastGazeExtension. I have correctly connected the back button to the UIButton outlet property in the controller, i.e. backBTN_FGE, and referenced an action function, i.e. backToWebPageMenu for the back button that wouldn't do anything for now.
Additionally, none of the referencing outlets show any inactive connections. How can I solve the following exception:

terminating with uncaught exception of type NSException
FastGazeController: Controller associated with the Storyboard.
Connections for the key under consideration:
All referencing outlets in the storyboard:
Note: I have copied this storyboard in my application from another application.
Go to your controller in storyboard. Delete the class name "ie: FastGazeController". Type it again and press enter.
Also check if you added the copied files to the target.
The first line of the warning/error stated:
2022-05-02 19:13:22.836066-0400 Application1[12433:4224720] [Storyboard] Unknown class _TtC8EApplication118FastGazeController in Interface Builder file.
The Interface Builder couldn't find the controller file and all of the subsequent referencing outlets were marked as not key-value coding-compliant.
After digging into the problem for some time, I found out that the target membership for folder (A) containing the controller file(B) included my application. However, target membership was not visible for the controller file itself. When I deleted folder A and added a new swift file(C) inside another folder that hadn't any visible target membership associated with it, and included logic of file B inside this new file/controller (C), it started working.
Note: I included my application directly as a target member of file C. I associated file C with the storyboard that I was working on.
Later on, I didn't face any issues with referencing.
After run application and click button, which is connected to next controller I get this error:

I don't have (and I didn't have) any "searchAnything". searchAnything is in another group/project. There I don't have any error.
Solutions from:
Terminating app due to uncaught exception 'NSUnknownKeyException' : iOS app crash
and
What does this mean? "'NSUnknownKeyException', reason: … this class is not key value coding-compliant for the key X"
didn't help me.
I don't know how to add all project here so I sent my mini-project-from-tutorial to sendspace
Go to storyboard and check whether the outlet connection is with Exclamation symbol if so remove it and then give proper connection to get it done.You have to select the appropriate viewcontroller which is getting crash.
This is because some outlet in the ViewController that you loading on click of button is not perfectly set. Please check for the following -
Main view outlet may not set
Any of the UIObject, may have double outlet(may be you change the object name and format to remove last outlet from the connection Inspector)
Push segue is deprecated from iOS 8.0 and later.
Temporary solution:
Change your Deployment Target to 9.0 and it will work.
Permanent Solution:
Create a new Xcode project copy all files except storyboards from existing project to new project and design the storyboard as per the existing one from the beginning.set your deployment target to iOS 8.0
I am a newcomer in developing. I make my project with TabBar. When I run my project on iPhone Simulator I can see FirstViewController. When I put on my Second Controller Icon on TabBar, project crashes and give me that issue.

Please, give me some solutions of this problem.
If you have provided a key in interface builder to some UILabel or any such UI instance of that missing key and then removed,that causes that error. Ctrl click the file's owner of view controller and remove the missing key(key with a yellow cross mark) from there.
Its the one of the answers I posted here on this SO thread whose problem looks just like yours.
I am not even sure how to search for this one I created a IBOutlet in storyboard and did the control drag to create the linking and gave it a variable name. There lies the problem I mistyped the variable named so i went in to the corresponding .h file and deleted the entry went back into storyboard and did the drag to the .h file and re-created the variable and the link this time I typed the variable name correctly. Now I get this uncaught exception error setValue:for undefined key( and it shows the misspelled variable I deleted.
I have since redeleted the good variable
ran a clean from the tools menu
closed the project and reopened it
if I do not have any variable I get the error and it points to what was the good variable name if I have the good variable loaded then I get the error pointing to the bad variable name.
ARRARAGGGHH
Things like this have happened before and I think it has something to do with XCode itself but I can't figure out how to fix it.
Currently I am running the the latest version of Xcode and my app project is based mainly on iOS6 if that helps any
the variables in question are
detailGraphic <---good
detailGrpahic <---bad
here is the message I see in the log when I have the good variable in place

Check the Connections Inspector (Cmd + option + 6) for this element in your Storyboard. You will see that it is connected (Referencing Outlets) to something that doesn't exist anymore. Undo that connection (click on the X for it) and you should be fine.
I have a rather peculiar error in my app
It only just started happening after it being fine for so long, all my nibs are wired up correctly from what I can see
Any other advice would be greatly appreciated
The error is as follows

If theres anything I can do to provide extra please let me know
Thanks all
This means that you have an outlet defined somewhere in your xib called 'MyTableView' and there is no property by that name.
Check all of your outlets!
