iOS Version Issue

[stevenbedrick]

Hello! The minimum iOS version specified in the project build settings is iOS 8, but the code (specifically CwlSignal.swift) calls os_unfair_lock_unlock(), which (according to the compiler) is not available in < iOS 10. Bumping the iOS deployment target up to iOS 10 fixes the issue and things compile normally. Would it be reasonable at this point to update the project to require iOS 10 at this point?
