Message from terminal.

[!] CocoaPods could not find compatible versions for pod "MHWebViewController":
In Podfile:
MHWebViewController (~> 1.0)

Specs satisfying the MHWebViewController (~> 1.0) dependency were found, but they required a higher minimum deployment target.

@KevinJue minimum is 9.0.
