fastlane: gym is failing when code signing (Sierra & Xcode 7 & gym 1.11.0)

Issue Description

Since when I updated to Sierra, fastlane is failing during code signing.

I tried to search for similar issues, but couldn’t find any.

If you are wondering why I’m using a Develop certificate, the reason is that I need to provide an app where I can use the Safari Web Inspector, and as soon as you use a distribution one you can’t use the inspector.

Complete output when running fastlane, including the stack trace and command used
