Code Signing Error: No signing certificate "iOS Development" found

Hello Everyone,

I would like to configure our CI Jenkins Build to sign our iOS App for development / distribution

After many days of research and confusion about the Apple signing process this is what I got:
A valid provisioning profile and a valid Signing certificate.
The Unity build output produces a xcodeproject.

In the XCodeProject the settings for:

Unity-IPhone --> Build-Settings --> Signing --> Code Signing Identity:

magically get set to "iOS Development" every time after the unity build completes

I do both:

1) setup the xcode project in a post build action:
pBXProject.SetBuildProperty(mainTargetId, "CODE_SIGN_IDENTITY", config.SigningCertificateName );
pBXProject.SetBuildProperty(mainTargetId, "CODE_SIGN_STYLE", "Manual");

as well as

2) calling xcodebuild from the console using:

xcodeBuild xcodeSchema: 'Unity-iPhone', ... jada jada ... , xcodebuildArguments: 'ENABLE_BITCODE=NO PROVISIONING_PROFILE=<The Guid of our provisioning profile> CODE_SIGN_IDENTITY="<The name of our Code signing certificate>" CODE_SIGN_STYLE="Manual"'

but still the CODE_SIGN_IDENTITY gets replaced by "iOS Development", which is not even installed on the mac. The provisioning profile and signing certificates available on the mac are only the ones used above.
I deleted all the others.

If I manually change the signing certificate to the one that should be used in xcode, I can archive export and install the app.

I just don't understand how the certificate gets messed up all the time.

Does someone have an idea how to fix this issue?

Any information would be appreciated.

Best Jochen

 

I have the same problem.

In my case, when I opened the Xcode project and checked Build Settings > Code Signing Identify, I found that the release was "iOS Developer". So I've avoided this by changing it to "iOS distribution" in a Unity script.
Of course, this is only a temporary solution until the root cause is found.

Code (CSharp):

1. public void OnPostprocessBuild(BuildReport report) {
2.     var summary = report.summary;
3.     if(summary.platformGroup != BuildTargetGroup.iOS) {
4.         return;
5.     }
6.  
7.     var pbxPath = summary.outputPath + "/Unity-iPhone.xcodeproj/project.pbxproj";
8.     var project = new PBXProject();
9.     project.ReadFromFile(pbxPath);
10.  
11.     var targetGuid = project.GetUnityMainTargetGuid();
12.     var releaseConfig = project.BuildConfigByName(targetGuid, "Release");
13.     project.SetBuildPropertyForConfig(releaseConfig, "CODE_SIGN_IDENTITY[sdk=iphoneos*]", "iPhone Distribution");
14.  
15.     project.WriteToFile(pbxPath);
16. }

 

I was able to solve this problem with setting the type of the provisioning profile in Unity:

Code (CSharp):

1. if (args.isAppStoreBuild)
2. {
3.    PlayerSettings.iOS.iOSManualProvisioningProfileType = ProvisioningProfileType.Distribution;
4. }
5. else
6. {
7.     PlayerSettings.iOS.iOSManualProvisioningProfileType = ProvisioningProfileType.Development;
8. }

By default iOSManualProvisioningProfileType == Automatic (you can find it in PlayerSettings), but for some reason it works incorrectly in some cases. So forcing it that way - helps.
