Apple association file fetched in development but not in TestFlight and App Store

问题

Universal links work perfectly fine in development, but once I sign the applications and deploy them to TestFlight and App Store, it looks like the apple-app-site-association is not fetched and therefore the app isn't registered for oppening the universal links.

1. /.well-known/apple-app-site-association file:

{  
  "applinks": {  
  "apps": [],  
  "details": [{  
  "appID": "myteamid.com.mycompany.appName",  
  "paths": ["*"]  
  }]  
  }  
} 

The server part looks OK, since it is successfuly fetched whenever I run the app via the cable on my phone.

App Search API Validation tool returns this for Link to application:

Action required

• Could not extract required information for Universal Links. Learn how to implement the recommended Universal Links.
• Error no apps with domain entitlements
• The entitlement data used to verify deep link dual authentication is from the current released version of your app. This data may take 48 hours to update.

2) Capabilities:

Associated domains - ON with Domain list of: applinks: link.mycompany.com

Other things I have turned on are: Push Notifications and Background Modes.

3) Provisioning profile: I created a new one after adding the Universal links and Push notifications and it includes:

Capabilities:

• Associated Domains,

• List item

• Game Center,

• In-App Purchase,

• Keychain Sharing,
• Push Notifications.

Entitlements:

• get-task-allow,

• app-enviroment,

• com.apple.developer.associated-domains,

• com.apple.developer.team-identifier,

• application-identifier,

• beta-reports-active,

• keychain-access-groups

4) While installing the app, it behaves different in test flight then it does when loading via cable:

• Via cable I can see the successfull http request for the apple-app-site-association file and finally form the process swcd: "Added service 'applinks', appID 'myteamid.com.mycompany.appName', domain 'link.mycompany.com' "

• Test flight - when installing there is no sign of http request and the following line is shown if I previously had the app installed via cable: "Removed service 'applinks', app ID 'myteamid.com.mycompany.appName', domain 'link.mycompany.com' (removed domain) "

This of course results in the fact that whenever I install the app via TestFlight or Describution, the Universal links do not work.

Any ideas where it goes wrong?

回答1:

I finally got to the bottom of this with help of Apple Developer Technical Support. In my (cordova) project folder there are two files:

Entitlements-Debug.plist Entitlements-Release.plist

When I add the value applinks:mywebpage.com to Capabilities->Associated domains->Domains, the Entitlements-Debug.plist got the lines:

<key>com.apple.developer.associated-domains</key>
<array>
  <string>applinks:mywebpage.com</string>=
</array>

BUT the Entitlements-Release.plist did not change. What I did to solve the issue is to copy-paste the generated lines form the Entitlements-Debug.plist. After this, I did the exact same Archive and upload process as before and everything worked fine.
