I'm new to Apple developing and soon I will distribute my app via AppStore. So now I'm using Swift 3 and by default the deployment target is set to iOS 10.0 It means that I won't be able to make it run for example on iOS 8-9? 'Cos in Swift 3 I use new funcs which are not available in later OS

推荐答案

你可以让你的应用在iOS 8上运行&安培; 9将部署目标设置为其中一个版本。 Swift 3.x与iOS 8兼容和更新（我不确定，但它可能也兼容iOS 7）。 Swift 2.2（关于系统要求）的唯一区别是你必须使用Xcode 8。

You can make your app run on iOS 8 & 9 by setting the Deployment Target to one of these versions. Swift 3.x is compatible with iOS 8 and newer (I'm not sure, but it might be also compatible with iOS 7). The only difference to Swift 2.2 (regarding the system requirements) is that you have to use Xcode 8.

当你将部署目标设置为早于iOS 10的版本时，你应该知道你不能使用iOS 10中新增的API。（除了你使用 #available operator）但是使用Swift 3应该没问题。

When you set your Deployment Target to an earlier version than iOS 10, you should be aware that you cannot use APIs that are new in iOS 10. (except you use the #available operator) But using Swift 3 should be no problem.

编辑：您现在可以使用Xcode 8.0 GM上传用 Swift 3 编写的应用

You can now upload apps written in Swift 3 using Xcode 8.0 GM
