iOS Universal Links and GET parameters

Question

we\'re trying to implement app indexing on iOS using the Apple Universal Links (I\'m looking at https://developer.apple.com/library/ios/documentation/General/Conceptual/AppS

Answer 1

In iOS 13, it's now possible to specify query and fragment values when defining universal link URLs. Sadly this isn't well documented by Apple, but it was mentioned in WWDC 2019: https://developer.apple.com/videos/play/wwdc2019/717/.

For your original example where you'd just like to match https://www.mywebsite.com?parameter=something, your apple-app-site-association file should look like:

{
  "applinks": {
    "apps": [],
    "details": [
      {
        "appID": "MYID",
        "components": [
          {
            "/" : "",
            "?": { "parameter": "something" }
          }
        ]
      }
    ]
  }
}

Note that you'll still need to specify a paths array if you want to continue supporting universal links in iOS 12, and iOS 13 devices will ignore the paths array if you specify a components array.
