How to set UICollectionViewCell height from cellForItemAtIndexPath?

So, I want to set UICollectionViewCell height from the cellForItemAtIndexPath instead of from 

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {

How can I do it? So I want to give height and width to my cells in cellForItemAtIndexPath, not in the collectionViewLayout: sizeForItemAtIndexPath

One way you can provide them estimate height with UICollectionViewFLowLayout

 UICollectionViewFlowLayout *flowLayout = (UICollectionViewFlowLayout*) self.CollectionViewLayout.collectionViewLayout;
    flowLayout.estimatedItemSize = CGSizeMake(self.view.frame.size.width,yourheight);

but if all the cell needs to have different heights then you need to implement sizeForItemAtIndexPath method form UICollecionViewController.

>        (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout
> sizeForItemAtIndexPath:(NSIndexPath *)indexPath{
>      return CGSizeMake(width, height);
>     
>     }

You have to still use sizeForItemAtIndexPath, but you may declare a public variable on the top of your swift file:

var cellSize = CGSize()

and in the cellForRowAtIndexPath delegate write something like this before return cell:

cellSize = CGSizeMake(100, 100) // set your desired width and height

then:

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
    return cellSize
}
