Firebase dynamic link not opening the app iOS

Question

I have developed & installed an iOS app locally on my device.

And have set custom scheme in the info.plist as mydlink

Set associated domains

Answer 1

After integrating Firebase Dynamic links, the sample link started working immediately on a device with iOS 8. For iOS 9 devices Universal links mechanism is used, as mentioned by other answers. This means Apple needs to update the entitlement data used to verify deep link dual authentication. This may take 48 hours, according to Apple's App Search API Validation Tool.

Answer 2

I have great news.

I always hear that it's IMPOSSIBLE to test a dynamic link on simulator.

But now WE CAN test firebase dynamic link on simulator

Answer 3

If none of the above workarounds work for you, please check if you have added activitycontinuation in associated domains or not.

Answer 4

Experienced the same problem.

The solution for me was to use the

Identifiers -> App IDs -> 'my.app.ID' -> Prefix

You can find it on: https://developer.apple.com/account/ios/identifier/bundle

Instead of the 'DevelopmentTeam' number from the .pbxproj which I used and add it to the Team ID for my iOS app in the Firebase console.

And don't forget to download and add a new .plist to the project.

Answer 5

We had a similar problem. The issue in our case was that the software that generated the emails with the links generated a new link that had a 304-redirect to our deep link. This did not work in Safari (but in Chrome).

Check that your deep link is actually the first link opened when you click the link in the email.

Answer 6

Firebase dynamic links were not working for us (on iOS9 where they use universal links) due to a problem in Firebase's assumptions during setup. Here's how we fixed the problem on our app:

Firebase asks for your "Team ID" when adding your iOS app to Firebase Console Project Settings, and it assumes that your unique app ID will be in the format TeamID.com.foo.bar

However, in our case, that was NOT our unique app ID. When I looked at our provisioning profile (on developer.apple.com I found our provisioning profile and clicked "edit"), I saw that our unique app ID was actually SomethingElse.com.foo.bar

I had to go into Firebase Console and enter that "SomethingElse" in the spot where it asked for Team ID, even though that was NOT our team ID. Once I made that change, Firebase Dynamic Links started working correctly.

It appears Firebase is making an assumption that your unique app ID will always start with your Team ID, which is apparently not always the case.

Note that changing your Team ID can take a significant amount of time to take effect. You can see that the change has happened by checking the appropriate link for your app_id (https://app_id.app.goo.gl/apple-app-site-association).
