I just updated the PR.

@a-ono the project cannot be built now. It's saying it can find AsyncDisaplyKit.
Why is there a nMessenger-iOS target and scheme?

[a-ono]

Probably you should run carthage bootstrap.

Why is there a nMessenger-iOS target and scheme?

Carthage requires a framework project that has shared schemes.

@a-ono why do I need to run carthage bootstrap?
I am using cocoapods. Why can't I run pod install and the project builds like before this PR was merged?
One should not block the other from working.
