My question is to get knowlegde regarding whether the app created for iphone 4 and 5 in ios 7 are supported in iphone 6 and iphone 6 plus or not??
If not supported then how i can provide support to the apps so that it can run in iphone 6 and iphone 6 plus
To provide iOS 8 support, need to xcode 6. As far as code is concerned, it depends on the xcode 6 requirement. We need to update only those functions those are deprecated in iOS 8. And for the UI, apple introduced 2 new screen size 4.7 and 5.5 inch. We need to use autolayout to manage the UI. Please let me know if any other issue. Thanks.
