Xcode 9 - failed to emit precompiled header [duplicate]

Answer 1

@Li Yakun This is the solution if you have more then one target in project, every new target in podfile must have:

target 'NEWTARGET' do
    # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
    use_frameworks!

    # Pods for MAINTARGET
    shared_pods
end
