The minimum supported target for AFNetworking 3.0 is iOS 7. The App Store doesn't care if you use Swift, Objective-C, or both.
however i heard that we cannot upload the app to appstore using Xcode 8 + Sierra which is targetting ios 7.
Is this true.?
I don’t know about the App Store upload side of this, but Xcode 8 no longer supports iOS 7 (I suspect you could still build an iOS 7 app, but there’s no device support that allows you to install and debug it).
