init methods, what causes them not to properly execute?

Im creating a UICollectionViewFlowLayout inside the init method of my UICollectionView.

-(instancetype)init
{
    self = [super init];


    UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc]init];
    layout.itemSize = CGSizeMake(106, 106);
    layout.minimumInteritemSpacing = 1.0;
    layout.minimumLineSpacing = 1.0;


    return (self = [super initWithCollectionViewLayout:layout]);
}

My delegate/datasource methods and viewDidLoad seems to execute, but for some reason if I add a breakpoint on the init method, it just silently fails.

Is it because the breakpoint causes everything conected to init method to quit along with the method?

No that's not the reason. Without the breakpoint the init method still wouldn't execute. The break point was added to see if it that block of code was being executed.

A breakpoint added at the ViewDidLoad halts execution.

Sorry it took so long to get back. If you haven't got it yet I think you mist a space, you wrote: 

UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc]init];

instead write this:

UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
