问题
Until now our project and all associated pods have been in objective c. We wanted to use the latest version of PromiseKit and so added use_frameworks! to our podfile. Before adding PromiseKit to the PodFile, I confirmed the project runs. After adding PromiseKit to the podfile, I get a 'Command /bin/sh failed with exit code -1' saying 'PromiseKit.framework: bundle format unrecognized, invalid, or unsuitable.'

Command /bin/sh failed with exit code 1
After removing DerivedData, Pods, .xcworkspace, and Podfile.lock, and then pod installing, this error still occurs.
回答1:
Try pod deintegrate, it worked for me to solve weird problems when I was migrating a project to use_frameworks!.
$ pod deintegrate Project.xcodeproj
$ pod install
I have documented the problems I had and how I fixed them here.
回答2:
I have the same error by other framework after upgraded to Xcode 8.3.1. Solved by removing ~/Library/Developer/Xcode/DerivedData/
