pod install fails after adding UITesting target to project

[tomschulz]

I added a new UI testing bundle to my project, and now when I run pod install. I did not modify the Podfile, I just created the targets and made a few tests. My test target and the tests worked, I did not notice I had broken Cocoapods until later when branch switches necessitated a new pod install.

The error output instructed me to file and issue so here I am. I have redacted the name of my UI test target, it is not really ****UITests.

I rand gem install cocoapods to make sure I had the latest version.

Error

RuntimeError - `PBXGroup` attempted to initialize an object with unknown ISA `PBXFileSystemSynchronizedRootGroup` from attributes: `{"isa"=>"PBXFileSystemSynchronizedRootGroup", "explicitFileTypes"=>{}, "explicitFolders"=>[], "path"=>"****UITests", "sourceTree"=>"<group>"}`
