Apple is incessantly coming with new iOS versions. Certainly, it brings new opportunities of iOS app developers to build innovative iOS apps. Can anyone tell me what advanced techniques iOS app developers use to develop app in 2016.

Technique remains the same; working with Xcode, Swift and the C family.
Whats new with this iOS 10 release comprises of some new APIs and services that enable developers to dig more into hardware based features, and deeper integration of Messages, Siri, Phone, and Maps into third party apps.
In a whole we can say, 2016 has been a great year for iOS developers with whole new set of tools & APIs, as well as a new development era where apps react on hardware signals.
