XCode deprecation problem?

I know that this is not a full on Unity related issue, but I have this problem where I export my IOS build to xcode and run it to my IPhone, but it comes up with 35 warnings saying that things are deprecated starting in IOS 8.1, and my build settings are set to the latest IOS version. I have no clue if it actually affects the game or not just curious. Thanks for your time!
