Supporting same domain on two different apps supporting universal links..?

Apple App Site Association file example

{
    "applinks": {
        "apps": [],
        "details": [{
            "appID": "D3KQX62K1A.com.example.photoapp",
            "paths": ["/albums"]
            },
            {
            "appID": "D3KQX62K1A.com.example.videoapp",
            "paths": ["/videos"]
        }]
    }
}

Important: The order of the dictionaries in the array determines the order the system follows when looking for a match. The first match wins, allowing you to designate one app to handle specified paths within your website, and another app to handle the rest.

In order to supporting Universal Links with single domain on two different apps you need to make changes in your existing apple-app-site-association file, at https://{domain}/apple-app-site-association.

For Single App Support

For single application support it's look like this

{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "1234ABCDE.com.domain.myapp",
                "paths": ["*"]
            }
        ]
    }
}

For Multiple App Support

For multiple application support, you need add one more key-value pair in details array of applinks in apple-app-site-association. It's look like this

{
    "applinks": {
        "apps": [],
        "details": [
            {
                "appID": "1234ABCDE.com.domain.myApp",
                "paths": ["*"]
            },
            {
                "appID": "1234ABCDE.com.domain.mySecondApp",
                "paths": ["*"]
            },
            {
                "appID": "1234ABCDE.com.domain.myThirdApp",
                "paths": ["*"]
            }
        ]
    }
}

General Format of apple-app-site-association file

The file looks like this:

{
"applinks": {
    "apps": [ ],
    "details": [
        {
            "appID": "{app_prefix}.{app_identifier}",
            "paths": [ "/path/to/content", "/path/to/other/*", "NOT /path/to/exclude" ]
        },
        {
            "appID": "TeamID.BundleID2",
            "paths": [ "*" ]
        }
    ]
}
}

How to support Universal Links in iOS App and setup server for it?

I found the solution, its pretty simple though. My problem was that my first app was supporting all the pages by stating

"*" in the paths section of apple-app-site-association file. Now all I have to do is add NOT in front of one of the paths which I wanted my second app to handle.

like "NOT /cabs". I haven't tested it yet if this works or not. I will post an update as soon as I am done with it.
