Seems to be a very old project file format - please open your project file in a more recent version of Xcode

fastlane finished with errors relating to automatic_code_signing. I’m not sure what this means and how to fix it, but it’s an error I hadn’t gotten before. I’m on Ionic v3.

Same here trying to rebuild a package with new certificates. Tried with old ones exactly the same configuration that was working a while back and now failing with this error.
Looked at this
BUT my old package build was fine with iOS project created with cordova-ios@4.5.5 and i can’t change to 5.1.1 as i want exactly the same build with only change in the certificates…
Any insight ?
