Dynamic cell width of UICollectionView depending o

Question

I have a UICollectionView, that loads cells from reusable cell, which contains label. An array provides content for that label. I can resize label width depending on content width easily with sizeToFit. But I cannot make cell to fit label.

Here's the code

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    arrayOfStats =  @[@"time:",@"2",@"items:",@"10",@"difficulty:",@"hard",@"category:",@"main"];
}

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:     (NSInteger)section{
    return [arrayOfStats count];
}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath{

    return CGSizeMake(??????????);
}

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{

    return 1;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    Cell *cell = (Cell *) [collectionView dequeueReusableCellWithReuseIdentifier:@"qw" forIndexPath:indexPath];
    cell.myLabel.text = [NSString stringWithFormat:@"%@",[arrayOfStats objectAtIndex:indexPath.item]];
    // make label width depend on text width
    [cell.myLabel sizeToFit];

    //get the width and height of the label (CGSize contains two parameters: width and height)
    CGSize labelSize = cell.myLbale.frame.size;

    NSLog(@"\n width  = %f height = %f", labelSize.width,labelSize.height);

    return cell;
}

let size = (arrayOfStats[indexPath.row] as NSString).size(withAttributes: nil)
