Hello, I'm having a hard time with Universal Links and my app.

This looks good:

$ curl -I https://www.bolsinga.com/.well-known/apple-app-site-association HTTP/1.1 200 OK Date: Mon, 12 Jun 2023 22:10:57 GMT Server: Apache/2.4.29 (Ubuntu) Last-Modified: Mon, 12 Jun 2023 20:53:38 GMT ETag: "1eb-5fdf4e9bcb926" Accept-Ranges: bytes Content-Length: 491 Content-Type: application/json

This looks good in my entitlements:

<key>com.apple.developer.associated-domains</key> <array> <string>applinks:www.bolsinga.com</string> </array>

The screenshot below good too (from Settings -> Developer -> Universal Links -> Diagnostics).

If I have a link like https://www.bolsinga.com/dates/sh624.html in Notes.app, and I tap on the link it will open in Safari. If I tap and hold, it will not suggest my application. It seems like my universal links should work. Am I doing it wrong? I thought it meant if I opened the URL in these ways it would open in my app.

Thanks for your help!

Hey @Bolsinga ,

You've got a capital 'L' in your AASA: it says "appLinks" instead of "applinks" so it looks like the CDN is not caching your AASA. Once you update that, you should be good to go! It will take a few days for the CDN to cache the AASA, as a heads up.

FWIW My app is a full SwiftUI lifecycle app, so it is using onOpenURL.

My app is on macOS too. By reading the transcripts of https://developer.apple.com/videos/play/wwdc2020/10098/, I found swcutil. Here is its output of sudo swcutil show --verbose. I have not denied it.

Service:              applinks
App ID:               D3F44CA7F4.gdb.SiteApp

I found openul:

$ sudo swcutil --verbose openul -u https://www.bolsinga/com/dates/sh624.html
NSOSStatusErrorDomain -10814 {
	_LSLine: "763",
	_LSFunction: "+[LSAppLink(Internal) _openWithAppLink:state:completionHandler:]"
}

It works great now that the CDN has caught up. Thanks again!
