Hi, When an SKStoreProductViewController (SKPVC) is quickly dismissed (before its presentation could complete), the "productViewControllerDidFinish:" delegate is not invoked at all. However, the debug view hierarchy still shows that the SKStoreProductViewController is presented on top of my view controller. At this point, all the UI components from my view controller's view are inaccessible (as they're presumably behind the SKPVC). When I tap on screen, the system removes the SKPVC from the view hierarchy & then I can access the app controls again. Here's my code for ref - Moreover, I see the following stack trace logged in the xcode console, when the SKPVC is dismissed.

I understand that objC has been around for a long time now. However, swift adoption has increased since it's launch & I believe most of the new iOS apps are built in swift.But, I'd like to understand what is the current market share of Swift vs Objective-C? Is there an official apple page that captures these stats?

I am using AVPlayer to play video files downloaded from a URL. Is there a way to determine what video MIME types are supported by AVPlayer?I tried using -[AVURLAsset audiovisualMIMETypes]which rerturns following supported MIME types for video - "video/3gpp2", "video/quicktime", "video/mp4", "video/avi", "video/x-m4v", "video/3gpp"However, when I use AVI files, the AVPlayer fails to play those & return error - "Failed to play media file".Is there a subtle & reliable way to determine what video formats does the AVPlayer support?Contradictorily, as per above list avi seems to be a supported type, but the isPlayable check on AVAsset returns false for avi files. (Why?) Strange!Note: I don't want to use isPlayable check on AVAsset object as it makes a network call & I have many files which makes it not preferable.
