Issue Description

I’m in the process of setting up fastlane on our CI box as a replacement of the (currently broken) Xcodebuild plugin for Jenkins. Everything works fine until the last step, codesigning, which fails with “unknown error -1=ffffffffffffffff”.

Last output from fastlane is

▸ Running script '[CP] Embed Pods Frameworks'

This only happens on our CI box (running macOS 10.12.4 and Xcode 8.3. fastlane and cocoapods are up-to-date)
