ios - What does deployment target mean?

Question

this is a very simple question I'm assuming. Can someone tell me what deployment target means. If I choose IOS 10, does that mean only users with iOS 10 can download the app. Is it bad to choose a lower deployment target? ALSO, continuing on deployment target, is it not recommended to run on a lower deployment target.

Answer 1

Lets say you have set minimum deployment target to iOS 9. This means your application is compatible for iOS 9 and above devices.

The application won't run on below 9.0 devices but can run on any iOS version greater than iOS 9.0.
