Issue TIMOB-16697:  iOS: SDK should have 0 compiler warnings (it currently has 9)
We should have 0 compiler warnings. An SDK that produces even 1 compiler warning should never make it to QE. There are 64-Bit issues buried in these 159 warnings, so these issues need to be fixed before our SDK can be certified as 64-Bit clean. This is Apple's guide to making source code "64-bit clean": [64-Bit Transition Guide for Cocoa Touch|https://developer.apple.com/library/ios/documentation/General/Conceptual/CocoaTouch64BitGuide]
