Appdelegate function in iOS(swift-UIkit) is not called when clicked on universal links

I have added applinks: example.com in my Xcode entitlements

This his my My app-site-association which I uploaded in web https://<fully qualified domain>/.well-known/apple-app-site-association :

{
    "applinks": {
        "details": [
            {
                "appIDs": [
                    "ABCDEF.com.abcdef.example"
                ],
                "components": [
                    {
                        "/": "/service/test",
                        "comment": "Matches URL with a path /service/test"
                    }
                ]
            }
        ]
    },
    "webcredentials": {
        "apps": [
            "ABCDEF.com.abcdef.example"
        ]
    }
}

My web credentials is working but not universal links

Below function is never called. I tried adding breakpoint and writing print statement

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool

Solution

  • First you need to check your Universal link Apple App Site Association(AASA). If your code is not triggering inside userActivity try validator first. And also your json looks wrong there is unnecessary comma inside appIDs.

    Asa Validator: https://branch.io/resources/aasa-validator/

    After that do not forget check NSUserActivityTypeBrowsingWeb

    func scene(_ scene: UIScene, continue userActivity: NSUserActivity) {
        
        if userActivity.activityType == NSUserActivityTypeBrowsingWeb {
         
        }
    }
