Please review above. Thanks.

Hey @mysticvalley. I'm not sure, this code sample still seems to work for me if I open in Xcode 10.2, change Swift version to Swift 4, and build and run on my iOS 12.2 iPhone X. However, there are several other solutions listed in the original context and answer here that might work better in your particular case: https://stackoverflow.com/a/52148520/2024046

(To test reloading, here's what I did:)

    override func viewDidAppear(_ animated: Bool) {
        DispatchQueue.main.asyncAfter(deadline: .now() + 2.0) {
            [weak self] in
            self?.collectionView.reloadData()
            print("reloaded collection view.")
        }
    }
