This happens when reload collection view

enter image description here

I am setting the collection view cell size based on my string in it. I use this code and the result is ok for the first time, when reloading the collection view for the second time or more this happens(see the image please)

this is my code : 

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        var i:Int = 0
        var size = CGSize()

        for t in mainCategoryDic {
            if(i == indexPath.row) {
                let index:String = t.key
                size = (mainCategoryDic[index]?.name?.size(withAttributes: [NSAttributedString.Key.font : UIFont(name:font_name, size: 14)!]))!
            }
            i += 1
        }

        return CGSize(width: size.width + 38.0, height: 30.0)
    }

Try this:

   func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        var size = CGSize()
        let t = mainCategoryDic[indexPath.item]
        let index: String = t.key
        size = (mainCategoryDic[index]?.name?.size(withAttributes: [NSAttributedString.Key.font : UIFont(name:font_name, size: 14)!]))!
        return CGSize(width: size.width + 38.0, height: 30.0)
    }
