iOS: performSegueWithIdentifier weird behavior - ios

This is totally weird behavior! I just have two view controllers, say, V1, V2. I'm trying to push V2 from V1 using performSegueWithIdentifier and it throws this error
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber pointSize]: unrecognized selector sent to instance 0xb0000000000000e5'
I have assigned segue identifier. I have cross checked the name of the segue, it looks perfectly alright with no spaces etc.
I tried presenting V2 using presentViewController method with storyboard id and it's working good, but not when I push it.
I tested another empty view controller V3 with same segue identifier(of course, I removed the identifier for V2), and it's working. So the problem is, it's throwing the error only with V2.
EDIT

So figure out where you're calling something that utilizes an applicationKey and figure out why it's blank :)

The error is saying that the collection view's data source is set to be a plain UIViewController instead of whatever class you have that implements UICollectionViewDataSource.
Check how your data source is assigned and what class of object it is.

Nasty Segue Error Message While Using Swift

I am relatively new to Swift and iOS in general. When I create a segue from a button to another view, I get a nasty error message (below). Can someone help me decipher this?

I'm not accessing any object inside NSArray which leads to following error, however certainly my app giving me this error.
The error is in your homePage method, which you can see here:
2 CoreFoundation ... -[__NSArrayI objectAtIndex:] + 164
3 MyApp ... -[AppManager homePage] + 203 <----THIS CALLS objectAtIndex: ABOVE
According to the error message, it is trying to access the index 18446744073709551615. This is the value of NSNotFound, which means you are probably handling NSNotFound incorrectly!
Issue with -[AppManager homePage] method kindly check if there is any array accessed there

Thread 1: signal SIGABRT xcode

I was recently trying to create a hidden button called signupComplete, and suddenly now I get this error everytime I try to run the app. here is the error message I recieve in the console:
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<SignupViewController 0x10a3519f0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key signupComplete.'
Im not sure why I am getting this. I even went back and removed anything that had to do with the signupComplete button, but I still keep receiving this error.
