Can you explain in a little bit more detail the steps you took to build the project? You shouldn't need to run cocos compile when doing an iOS build. Did you follow the steps on this page? Make sure your Cocoapods are up to date too (pod update). Also make sure you're running the .xcworkspace file and not the .xcodeproj file, if you weren't already.

Sorry, I don't know IOS plataform, I install "pod" and all work perfect.
