Apple introduced a bug with the codesign tool in OS X 10.9.5 that is mentioned in: http://stackoverflow.com/questions/26008449/xcodebuild-codesign-vvvv-saysresource-envelope-is-obsolete
Codesign fails for some configurations with the message: "resource envelope is obsolete (custom omit rules)."
There is a workaround: "The command line tool “codesign” has changed in 10.9.5 and 10.10, you need to pass “--no-strict” option to the command, (the problem has been reported and will be fixed)."
Xamarin could work around the Apple bug with the following code change to Xamarin.iOS.Tasks.Core.dll:
public abstract class CodesignVerifyTaskBase : Xamarin.MacDev.Tasks.CodesignVerifyTaskBase
protected override string GenerateCommandLineCommands()
ProcessArgumentBuilder processArgumentBuilder = new ProcessArgumentBuilder();
processArgumentBuilder.Add( "--verify" );
new --> processArgumentBuilder.Add( "--no-strict" );
processArgumentBuilder.Add( "-vvvv" );
processArgumentBuilder.Add( "-R='anchor apple generic and certificate 1[field.1.2.840.1136188.8.131.52.1] exists and (certificate leaf[field.1.2.840.1136184.108.40.206.2] exists or certificate leaf[field.1.2.840.1136220.127.116.11.4] exists)'" );
processArgumentBuilder.AddQuoted( this.Resource );
Note the addition of the no-strict parameter. I tested this parameter and found it to work around the Apple bug for my projects.
From what I can see Apple's bug is already fixed in the latest versions of OS X 10.10, and our next version of Xamarin.iOS will require Xcode 7, which requires OS X 10.10, so as far as I can tell we don't need to work around Apple's bug (since the next version of Xamarin.iOS won't work on 10.9 anyway).
This codesign misbehavior is occurring with OS X 10.10 and XCode 7. I discovered the problem yesterday after upgrading both. I also tested the work around and found that it resolves the failure.
Correction: I upgraded to OS X El Capitan which is 10.11 -- not 10.10.
Check your Info.plist for a CFResourceRules (I think?) key. If it exists, then that is the problem.
I recently made a fix related to this.
Oops, the Info.plist key is CFBundleResourceSpecification
*** Bug 34845 has been marked as a duplicate of this bug. ***
The problem is that the iOS SDK you're using uses custom resource rules when signing, which are no longer supported on OS X 10.9.5 and later.
Removing the custom resource rules should fix the codesign issue.
With the cycle6 release published today, this should no longer be a problem since we no longer specify ResourceRules.
