I am encountering a problem on landscape orientation for my collection view cell. When the app is in portrait it gives me the correct number of cell per row which is 2. But when

Here is what you can do

let orientation = UIApplication.sharedApplication().statusBarOrientation
if(orientation == .LandscapeLeft || orientation == .LandscapeRight)
{
    return CGSizeMake((yourCollectionView.frame.size.width-10)/2, (yourCollectionView.frame.size.height-10)/2)
}
else{
    return CGSizeMake((yourCollectionView.frame.size.width-5)/2, (yourCollectionView.frame.size.height-10)/3)
}

What this code achieves:- If your view is in portrait you will see 2 column and 3 row and if your view is in landscape you will see 3 columns and 2 row. The deduction you see in the code is the spacing between two consecutive cells. So if there is 3 column the deduction is 15 and if there is 2 column the deduction is 10 assuming that the spacing between two cell is 5. Same goes for the row.

You can use the screen size as well if you want but I had auto layout constraints in my collection view to match the size of the screen so it resulted the same. I hope this is what you were looking for.
