正如@azdev在Xcode的新版本中所指出的那样，你会在尝试我之前的解决方案时遇到编译错误，要解决这个问题，只需按照建议进行编辑即可使用！来解包捆绑字典！

As pointed out by @azdev on the new version of Xcode you will get a compile error for trying my previous solution, to solve this just edit it as suggested to unwrap the bundle dictionary using a !

let nsObject: AnyObject? = NSBundle.mainBundle().infoDictionary!["CFBundleShortVersionString"]

结束编辑

只需使用与Objective-C相同的逻辑，但只需进行一些小改动

Just use the same logic than in Objective-C but with some small changes

//First get the nsObject by defining as an optional anyObject
let nsObject: AnyObject? = NSBundle.mainBundle().infoDictionary["CFBundleShortVersionString"]

//Then just cast the object as a String, but be careful, you may want to double check for nil
let version = nsObject as String

我希望这能帮到你。
