I've released an app for iPhone. My deployment target is 7.0, base SDk latest. and it work fine on the latest version iphones, but some people are saying it doesnt work on their phone, when I asked what version they are running, they say below 7.1 so something like 7.0.4. I went on apple documentation, https://developer.apple.com/LIBRARY/IOS/releasenotes/General/iOS71APIDiffs/index.html
the only one that applies to me is SKView.showsPhysics, I only added this during development to test my physics, but i left the code and set the boolean as NO, is this the reason why it crashes on iOS < 7.1 , as it was added after 7.1?
