I am calling a function through another view controller with:
perform(#selector(MainScreenViewController().test))
The action is called test and it is located in the MainScreenViewController().
Once it reaches this code the application crashes with the following crash report:
2018-01-20 13:24:46.800692+0100 Business Name[40750:3947268] -[Business_Name.RPLabel test]: unrecognized selector sent to instance 0x7fd444d03e30

libc++abi.dylib: terminating with uncaught exception of type NSException
The app sometimes crashes with [NSObject(NSObject) doesNotRecognizeSelector:], the selector being [UIImageView setImage:].
I captured it by setting an exception breakpoint and the crash happens when setting an UIImageView.image in prepareForReuse of a UICollectionViewCell:
class MyCell: UICollectionViewCell {
var coverImageView = UIImageView()
...
override func prepareForReuse() {
super.prepareForReuse()
coverImageView.image = nil
}
}
The prepareForReuse is called then the cell is instantiated:
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = myCollectionView.dequeueReusableCell(withReuseIdentifier: "myReuseID", for: indexPath) as! MyCell
...
}
Why is that happening?
Also I cannot load the quick look data view for the UIImageView so maybe the object has been released?
The error messages in console are:

I think the problem is that you are not calling the designated initializer of UIImageView, therefore its image property is not properly initialized and trying to assign to it crashes the app:
-[NSMallocBlock size]: unrecognized selector sent to instance 0x608000880aa0
The method tries to call the size method on the old image but the old image was set to some random memory address.
To fix it, initialize UIImageView properly using the designated initializer:
var coverImageView = UIImageView(image: nil)
Before you say "this is a repeat of a question", no. I have checked the question before and all it tells me is to check my outlets. All my outlets are correct and I'm not sure why I'm getting this error. Here's the error in detail :

libc++abi.dylib: terminating with uncaught exception of type NSException

Looks like the Info.plist of your app may not have a proper values for NSAppTransportSecurity or one of its children.
Check out: MPCoreInstanceProvider.m.
"this is a repeat of a question" - next time look at your stack trace, it contains all the hints required:
Close to the top you have the -[NSObject(NSObject) doesNotRecognizeSelector:] which is throwing the exception (objc_exception_throw ...)
doesNotRecognizeSelector means that some code tried to invoke a method which is not available
which one? Look further above: -[NSTaggedPointerString objectForKeyedSubscript:]
so the method missing is objectForKeyedSubscript: which is what the Objective-C compiler generates for an expression like: myObject[#"title"]
it also tells you the class of the object the method is invoked on: NSTaggedPointerString, so some code tried to use [] on a plain string, which doesn't make much sense
Next thing to check is who invoked that code: -[MPCoreInstanceProvider appTransportSecuritySettings] is the last regular code in the stack
so you DuckDuckGo MPCoreInstanceProvider and find MPCoreInstanceProvider.m
which happens to have a appTransportSecuritySettings method
looking into the code it grabs a dictionary NSDictionary *atsSettingsDictionary = [NSBundle mainBundle].infoDictionary[kMoPubAppTransportSecurityDictionaryKey];
and then does a lot of [] operations on that dictionary and values of it
Conclusion: One of the [] is hitting a string when it was expecting a dictionary.
Could anyone help me understand why Im getting this error? It seems to be happening when I load one of my view controllers but I can't see why.
What usually causes an error like this?

Please ask for any other informations that is helpful
Thanks
You most likely have an Outlet assigned to an element on the view controller you are transitioning to that is no longer connected to your code. This youtube video explains it in more detail.
To hunt down this issue, try right-clicking on all your elements (UILabels, UIViews, UIButton...) with the assistant editor open and cross check to see if the outlet name is referenced in the view controller.
I have integrated AdMob into My Application. Now when i am pushing to the AdMob view it constantly gets crashed.
Here is the Crash log :

Thanks.
Go to project settings > Build Settings And set -ObjC to Other Linker Flags.
More info: https://stackoverflow.com/a/22585112/2115477
I referred few discussions & found that there is an flag need to be added in build settings.
Here it is :
Targets -> Build Settings -> Linking -> Other Linker Flags
I set here -ObjC
So now its working.
