Sign In With Apple, Cloud Build Version

Hey everyone,

I'm currently in progress of setting up Sign In With Apple. I don't work on a Mac and therefore I don't have XCode available. For this to work, I need to add the capability to the entitlements, and add a AuthenticationServices framework to my list of frameworks.

I was using: https://blogs.unity3d.com/2019/09/19/support-for-apple-sign-in/ as a reference initially.

However, Unity doesn't like to provide documentation on how to do such things for Cloud Build.

I've tried a few builds now and it seems the AuthenticationServices framework is being added correctly. But I don't think the capability is being added correctly.

When attempting to sign in for apple, I get this error: com.apple.AuthenticationServices.AuthorizationError error 1000.

We use One Signal as well, so I've been trying to reference a bit of how they get themselves organized for the IOS PostBuild as well. So far, hasn't been working out.

I've posted the IOSPostBuild script I'm using. This is a file that I didn't start, but another person started that I work with. The only changes I've made involve AuthenticationServices.framework and the sign in capability.

Any information or help would be appreciated!

Code (CSharp):

1. public class IOSPostBuild
2. {
3.     public static readonly string DEFAULT_PROJECT_TARGET_NAME = "Unity-iPhone";
4.  
5.     [PostProcessBuild(1)]
6.     public static void OnPostProcess(BuildTarget buildTarget, string buildPath)
7.     {
8. #if UNITY_IOS
9.         if (buildTarget == BuildTarget.iOS)
10.         {
11.             //UPDATE THE PLIST
12.             string plistPath = buildPath + "/Info.plist";
13.             PlistDocument plist = new PlistDocument();
14.             plist.ReadFromString(File.ReadAllText(plistPath));
15.             PlistElementDict rootDict = plist.root;
16.             rootDict.SetString("NSCameraUsageDescription", "Improve the quality of service of this product");
17.             rootDict.SetString("NSLocationAlwaysUsageDescription", "Improve the quality of service of this product");
18.             rootDict.SetString("NSLocationWhenInUseUsageDescription", "Improve the quality of service of this product");
19.  
20.             rootDict.SetBoolean("NSAllowsArbitraryLoadsForMedia", true);
21.             rootDict.SetBoolean("NSAllowsArbitraryLoadsInWebContent", true);
22.  
23.             string exitsOnSuspendKey = "UIApplicationExitsOnSuspend";
24.             if(rootDict.values.ContainsKey(exitsOnSuspendKey))
25.             {
26.                 rootDict.values.Remove(exitsOnSuspendKey);
27.             }
28.  
29.             PlistElementArray bgModes = rootDict.CreateArray("UIBackgroundModes");
30.             bgModes.AddString("remote-notification");
31.             File.WriteAllText(plistPath, plist.WriteToString());
32.  
33.             // UPDATE THE  PBXProject
34.             var projectPath = PBXProject.GetPBXProjectPath(buildPath);
35.  
36.             var project = new PBXProject();
37.             project.ReadFromFile(projectPath);
38.  
39.             var mainTargetName = DEFAULT_PROJECT_TARGET_NAME;
40.             var mainTargetGUID = project.GetUnityMainTargetGuid();
41.             var unityFrameworkGUID = project.GetUnityFrameworkTargetGuid();
42.  
43.             Dictionary<string, bool> frameworks = new Dictionary<string, bool>
44.             {
45.                 { "Security.framework", false },
46.                 { "AuthenticationServices.framework", true }
47.             };
48.  
49.             foreach (KeyValuePair<string, bool> framework in frameworks)
50.             {
51.                 project.AddFrameworkToProject(unityFrameworkGUID , framework.Key, framework.Value);
52.             };
53.  
54.             project.AddCapability(mainTargetGUID, PBXCapabilityType.SignInWithApple);
55.             var entitlementPath = project.GetBuildPropertyForConfig(unityFrameworkGUID, "CODE_SIGN_ENTITLEMENTS");
56.  
57.             ProjectCapabilityManager pcm = new ProjectCapabilityManager(projectPath, entitlementPath, mainTargetName, mainTargetGUID);
58.             pcm.AddSignInWithApple();
59.             pcm.WriteToFile();
60.  
61.             project.WriteToFile(projectPath);
62.  
63.         }
64. #endif
65.     }
66. }

 

Did you ever solve this?

 

I also use Cloud Build to make my iOS builds. Having the exact same issue and no idea how to fix this, or what the issue is exactly.

 

I am still stuck with this too but I would recommend you to

- inspect the PList and entitlements file generated from unity local build. Copy it somewhere
- Add capability in xcode like that video told you to do
- Diff the cached and the result of xcode

I suspect that it related to some key in entitlements file that xcode doing something internally more than we expect

maybe this post was the reason : https://forum.unity.com/threads/add-sign-in-with-apple-entitlement-any-success.875566/#post-5767423

 

Not sure it related but I have add capability to both target

Code (CSharp):

1.  
2.         foreach(var guid in new [] { proj.GetUnityMainTargetGuid(),proj.GetUnityFrameworkTargetGuid() })
3.         {
4.             var m = new ProjectCapabilityManager(projPath,"Unity-iPhone/Unity-iPhone.entitlements",null,guid);
5.             m.AddSignInWithApple();
6.             m.AddInAppPurchase();
7.             m.WriteToFile();
8.         }
