Declare variable without type

I need to declare a variable as follows:

var cell

if cond {
    cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as? CustomCell1
}
else {
    cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as? CustomCell2
}

The problem here is that I get the error Type annotation missing in pattern.

Of what type should I declare my variable or is there a workaround this issue?

Assuming that CustomCell1 and CustomCell2 inherit from UICollectionViewCell you can do the following:

var x: UICollectionViewCell?

if cond {
    x = CustomCell1()
}
else {
    x = CustomCell2()
}

Then when you want to use it as a specific type of cell you use this:

if let cell1 = x as? CustomCell1 {
    //Use cell1 here
}

if let cell2 = x as? CustomCell2 {
    //Use cell2 here
}
