i have different realm objects in different ViewControllers and from my settingViewController i'm deleting all the data of app (the realm stored objects ) its working fine but when i move back to those viewControllers i got this exception :
Terminating app due to uncaught exception 'RLMException', reason: 'Object has been deleted or invalidated.'

i know its happening because system (kernel , iOS) dont knows that i've deleted those Realms Objects and system is trying to use that data which is not exists anymore (Correct me if i'm wrong) , any one can guide me on how i can fix this problem ???
I suggest you to make notification before deleting all your data to all view controllers, that manipulate with it:
Push notification from your settingViewController before wipe
Subscribe to this everywhere you need to clear objects.
delete references
perform clean in your settingViewController.
Or, other way - implement delegate pattern for your purpose. The idea is the same.
Hope this helps.

I was updated xcode today.
When I want to show some viewController (without collectionView & tableView), I’ve got crash in AppDelegate and debug info:
Terminating app due to uncaught exception 'NSGenericException', reason: 'This coder requires that replaced objects be returned from initWithCoder:’
Anyone solved this problem?
Check your ViewController for injected Object references. It may be caused by external class from some Pod Repository. Remove it and define all the logic inside the VC class. This solved the issue for me. VC Scene
I have a SpriteKit game, but now I'm working on making a menu. I decided to try to make these menus in a normal way, using Storyboards and UIViewControllers.
However, this is proving to be very difficult.
I added a new UIViewController, and set it as the initial viewcontroller. This causes no problems. However, as soon as I hook this up to a completely basic UIViewController file (FirstMenuViewController.m), with no edits or additions, ViewController.m seems to freeze up at if(!skView.scene){.
I'm getting this error:
-[UIView scene]: unrecognized selector sent to instance 0x170164980
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView scene]: unrecognized selector sent to instance 0x170164980'

....

What I don't get is why ViewController.m is even called, as there is no connection to that file from my FirstMenuViewController which is set as the initial viewcontroller.
Could someone please explain to me what is going on here?
Turns out I was subclassing the ViewController supplied by the SpriteKit-template instead of UIViewController when creating my FirstMenuViewController
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:

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 kind of a novice to programming and I thought I could find help here.
I am trying to make an app where when you click on the table view cell, it shows more detailed information. When you click the cell, the debug area opens up and I am given the following message:

Does anyone know what I am doing wrong? I can post some of my code if you'd like.
The IBOutlet is either disconnected in the xib file for the tableView or connected to some unwanted element.
I'm implementing UIButtons with block actions set on them for connivence and speed of integration. I've used this method before, a while ago now, and had little issue with it. Now, however, i'm facing an issue where integrating...

... i've never seen this issue before but it's odd that it is immediately crashing without any interaction.
Thanks in advanced.
You must make sure to add the implementation file of the category to your target. In Xcode, go to the File Inspector and make sure the Target Membership checkbox for your target is checked.
