I know it exists because this gist https://gist.github.com/mbleigh/9c8680cf319ace2f506f57380da66e7d results in this output:

@asikand Have you tried removing .json from the filename? The file should be stored without any extension.

asikand · 2020-02-10T19:12:53Z

I tried it both with and without .json from the file name. I thought the whole gz problem had to do with it not correctly identifying the right file type.

My AASA is now working through the Dynamic Links page.link url: https://freeyourtaste.page.link/apple-app-site-association

But I still can't get it working with hosting.

asikand · 2020-02-10T19:27:47Z

@stleamist I re-uploaded the files and deployed them to hosting this time without the .json file extension.

Now if I access:
https://fyt-app-8d46e.firebaseapp.com/apple-app-site-association
it just downloads a GZIP file again.

I really don't know why the Content-Type header is not working.

I tried grabbing the file with curl and I can see on the request
Content-Type: application/json and the file looks fine. When I access through the browser I get the GZIP

To prevent the browser from reading the bytes and automatically inferring the MIME type I even added this to the headers:
X-Content-Type-Options: nosniff but it's still not working.

stleamist · 2020-02-10T22:12:55Z

@asikand It seems like your website is working as expected for me. Could you try this without cache or on another browser?

And I've into the /hosting/dist/site/.well-known/ the file apple-app-site-association with this json:

{
	"applinks": {

				"appID": "8XP55WY44Z.com.my.enterprise.contactless",

	}
}

When I try to validate it with https://branch.io/resources/aasa-validator, I've a empty result (all check passes):

{
    "applinks": {
        "apps": [],
        "details": []
    }
}

I've read that I should have to add a "appAssociation":"NONE" into hosting object in firebase.json file.
But if I add it, I receive a validation error from branch.io/resources/aasa-validator.

So, how can I set a right configuration to handle the aasa functionality?

HasanAboShally · 2021-03-29T17:31:42Z

Facing the same issue :/

Did you manage to solve it?

Aviditi-Blake · 2021-07-08T02:54:19Z

So I noticed without "appAssociation": "NONE", Firebase hosting creates an empty apple-app-site-association file that gets picked up instead of the one at .well-known. In addition, the Apple site validator doesn't even work, but the configuration below shows all good at https://branch.io/resources/aasa-validator and actually works in routing to my app when hitting the specified urls.

I also had to actually have a resource our rewrite at the specified URL in order for the application to actually open however, so I ended up adding an extra re-write in the firebase.json because I wanted a path that was solely meant for app associations.

What Worked For Me

In firebase.json:

{
...
"headers": [
      {
        "source": "/.well-known/apple-app-site-association",
        "headers": [
          {
            "key": "Content-Type",
            "value": "application/json"
          }
        ]
      }
 ],
"rewrites": [
      {
        "source": "/universallink/*",
        "destination": "/privacypolicy.html"
      }
],
 "appAssociation": "NONE",
 ...
}

And in /.well-known/apple-app-site-association file:

{
    "applinks": {
    "details": [
        {
             "appIDs": [ "TEAMID.com.example.app", "TEAMID.com.example.app.dev", "TEAMID.com.example.app.beta" ],
             "components": [
              {
                "/": "/universallink/*",
                "comment": "Matches any URL whose path starts with /universallink/"
              } ]
         }
      ]
   }
}

@mbleigh is this still on the bug list or is it a keeper?

radykal · 2022-09-18T19:12:14Z

If someone is looking for a solution to use a custom apple-app-site-association file with dynamic links. Here you go. I just added a redirect from /apple-app-site-association to /.well-known/apple-app-site-association.

"hosting": {
        "public": "build",
        "ignore": [
            "firebase.json",
            "**/.*",
            "**/node_modules/**"
        ],
        "headers": [{
            "source": "/.well-known/apple-app-site-association",
            "headers": [{
                "key": "Content-Type",
                "value": "application/json"
            }]
        }],
        "rewrites": [
            {
                "source": "/share/**",
                "dynamicLinks": true
            }
        ],
        "redirects": [{
            "source": "/apple-app-site-association",
            "destination": "/.well-known/apple-app-site-association",
            "type": 301
        }],
        "appAssociation": "AUTO"
    }

Premodial · 2022-11-07T06:21:50Z

Hi I have the configuration below. But it seem like my https request just get the default firebase index.html and its not opening my app. I tried even deleting the index.html in the public folder.

{
"hosting": {
"public": "public",
"site":"soco-app-v01",
"headers": [
{
"source": "/.well-known/apple-app-site-association",
"headers": [
{
"key": "Content-Type",
"value": "application/json"
}
]
}
],
"appAssociation": "NONE"
}
}

riazhazan · 2023-04-10T03:48:16Z

@Blackjacx

which commands do you use to upload the apple-app-site-association file and where exactly must it be? Can somebody pls post how the firebase json has to look that this works?

There are 4 things to check:

The apple-app-site-association file should be placed at the root of your server or in the .well-known subdirectory.

The apple-app-site-association file should be served on the HTTPS. (This is done by Firebase.)

The apple-app-site-association file should be served as the application/json MIME type, without appending .json to the filename. By setting a custom header in firebase.json, it can be done.

Even though the Dynamic Links is not set, the Firebase overrides the apple-app-site-association file in / and /.well-known to its own file by default. To avoid this, the appAssociation property in firebase.json should be set to NONE.

Then the firebase.json file should be like below:
{
  "hosting": {
    "public": "public",
    "headers": [
      {
        "source": "/.well-known/apple-app-site-association",
        "headers": [
          {
            "key": "Content-Type",
            "value": "application/json"
          }
        ]
      }
    ],
    "appAssociation": "NONE"
  }
}

This saved my time. I was chasing this for 2 days and this saved my time.

Tak783 · 2023-04-24T18:29:24Z

Ok, so this is what I did to make it work

Deleted the apple-app-site-association file
Recreated it via terminal with the following command touch apple-app-site-association (note, there is no .json)
Moved the apple-app-site-association to the public folder at the root + also added the well known folder too public/.well-known/apple-app-site-association

I then verified with https://branch.io/resources/aasa-validator/
I also then went to https://_my_redacted_app+name/.well-known/apple-app-site-association and saw the expected JSON from apple-app-site-association

The code looks like this

Firebase.json file

{
    "hosting": {
        "public": "public",
        "headers": [
            {
                "source": "/.well-known/apple-app-site-association",
                "headers": [
                    {
                        "key": "Content-Type",
                        "value": "application/json"
                    }
                ]
            },
            {
                "source": "apple-app-site-association",
                "headers": [
                    {
                        "key": "Content-Type",
                        "value": "application/json"
                    }
                ]
            }
        ],
        "appAssociation": "NONE"
    }
}

apple-app-site-association

    "applinks": {
        "details": [
            {
                "appIDs": [ ""_my_redacted_app_id.my_redacted_bundle_id""],
                "components": [
                    {
                        "/": "/public/*",
                        "comment": "my_redacted_comment"
                    }
                ]
            }
        ]
    }
}

putting it in public/.well-known solved it for me. Note, I also didn't need to include the appAssociation line in firebase.json, seems they fixed that bug.

But when I try hitting the URL in the app, it is not opening the app.
