Hi, I am using a standalone CollectionView object in a ViewController that has many other elements other than the collection view.   var testCV : UICollectionView! in loadView:   let flowLayout = UICollectionViewFlowLayout()   let photoCollectionViewLayoutFrame = CGRect(x: 0, y: 0, width: scrollView.bounds.width, height: CGFloat(150))     testCV = UICollectionView(frame: photoCollectionViewLayoutFrame, collectionViewLayout: flowLayout) Creating the object, and setting up its Flow Layout seems fine, and I am conforming to the respective Flow Layout, Data Source and Delegate protocols. Setting the data source works as expected.    override func viewDidLoad() {     super.viewDidLoad()           testCV.delegate = self     testCV.dataSource = self           print(testCV) //    newListingForm.photoCollectionView!.delegate = self as UICollectionViewDelegate //    print(newListingForm.photoCollectionView?.delegate) //    newListingForm.photoCollectionView.dataSource = self //    print(newListingForm.photoCollectionView)   } However, the delegate is nowhere to be found when I print out the CollectionView Object. Optional(<UICollectionView: 0x7fd74b06b400; frame = (0 0; 0 150); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x6000023ed3e0>; layer = <CALayer: 0x600002dcea80>; contentOffset: {0, 0}; contentSize: {0, 0}; adjustedContentInset: {0, 0, 0, 0}; layout: <UICollectionViewFlowLayout: 0x7fd749d26680>; dataSource: (null)>) And when I debug, the delegate property is missing. Am I using CollectionView wrong?
