I am trying to run a Cocoapods project and getting the following error

I tried to pod deintegrate and then pod install but it's still there.
I also tried removing the pod.debug.xcconfig file from Project->Info->Configuration and then pod install but nothing.
pod.debug.xcconfig generated by pod install contain path like ${PODS_ROOT}/Headers/Public/AttributedMarkdown

but I can't find 'Headers/Public' in Project Navigator
