why universal links are not working even though validated right by apple?

When validating my apple app site association file, I get passed for the main domain and sub domains

aasa

and of course have entitlements enabled and added

associated domains

I reinstall the app whenever I want to test on a device, to fetch a new version of the file installed on the device... and I delete the old app before installing from XCode.

{
    "applinks": 
    {
        "apps": [],
        "details": [
            {
                "appID": "TeamID.AppID",
                "paths": [ "*" ]
            }
        ]
    },
    "activitycontinuation": 
    {
        "apps": ["TeamID.AppID"]
    }
}

but the problem simply is, when I tap links from an html that i hosted online, it opens in safari not in app!!

PS : is this because I don't have https for the site? it works only on http...

Solution

  • The real answer in this case is that the apple-app-site-association file needs to be accessible over HTTPS. From the App Search Programming Guide:

    NOTE

    If your app runs in iOS 9 or later and you use HTTPS to serve the apple-app-site-association file, you can create a plain text file that uses the application/json MIME type and you don’t need to sign it. If you support Handoff and Shared Web Credentials in iOS 8, you still need to sign the file as described in Shared Web Credentials Reference.

    For iOS 8 you needed to sign the JSON file, so in that case it was fine to be offered over HTTP, since it was validated via the signature. With more recent iOS versions, it doesn't need to be signed, which is great, but then we need HTTPS to secure it.

    Original irrelevant answer:

    If you're already in Safari, I believe it will stay in Safari. You should try the link in another app like Notes. Also, your phone may be configured to always go to the web for that link. In that case, you can long press on the URL in Notes again, and you should get prompted whether you want to open the app or go to the web.
