iOS 13 AASA file not downloading

Question

I noticed that the AASA file is not downloaded (by monitoring the API calls in Charles) on iOS 13.1. I was going through the WWDC https://developer.apple.com/videos/play/wwdc2019/717/ video, but could not find any hint whether we need an additional step on iOS 13.

Anyone experienced the same problem? It works on iOS 12.2 and earlier.

Answer 1

You can check in your console for error if any during file download on first installation https://ios13.dev/universal-links-debugging-on-ios-13-cjwsux93w001p6ws1swtstmzc
