Answer 1

The problem is that you are calling thumbnailForVideoAtURL on a background thread. You need to be on the main thread because you are talking to the interface.

tempDkAsset.fetchAVAssetWithCompleteBlock { (tempVideo, info) in
    DispatchQueue.main.async {
        tempImageView.image = self.thumbnailForVideoAtURL(tempVideo!)
    }
}
