Unable to Set Initializer for Custom UICollectionView Cell Class

if your 'Key' is not optional then you need to initialize the 'key' in Init().

public required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    // do something here if you need ... 
}

The decoder is useful if you want to restore your object to customer object.For example, if you store a class object in core data and read the record from core data then you need to do encode and decode for it.

You need to set a default value to your key variable or make it Optional

var key: String?

you need to include the initializer for NSCoder:

public required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    // do something here if you need ... 
}

That should fix it for you.
