使用Swift获取版本和构建信息 [英] Getting Version and Build Info with Swift

问题描述

我试图访问Main NSBundle以检索版本和构建信息。事实是，我想在swift中尝试它，我知道如何在Objective-C中使用 Build.text = [[[NSBundle mainBundle] infoDictionary] objectForKey：@CFBundleVersion]; 。但我不知道从哪里开始使用swift，我试图用新的语法编写它，但没有用。感谢您的帮助！

I am attempting to gain access to the Main NSBundle to retrieve Version and Build information. Thing is, I want to try it in swift, I know how to retrieve it in Objective-C with Build.text = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];. Yet I don't know where to start with swift, I have attempted to write it in the new syntax with no avail. Thanks for any help!

推荐答案

Swift语法出了什么问题？这似乎有效：

What was wrong with the Swift syntax? This seems to work:

if let text = Bundle.main.infoDictionary?["CFBundleVersion"]  as? String {
    print(text)
}
