使用UiDevice获取设备信息：
let name = UIDevice.currentDevice().name
let systemName = UIDevice.currentDevice().systemName
获取系统版本
let systemVersion = UIDevice.currentDevice().systemVersion
获取设备模型
let model = UIDevice.currentDevice().model
获取设备本地模型
let localizedModel = UIDevice.currentDevice().localizedModel
Swift获取Bundle的相关信息：
let infoDict = NSBundle.mainBundle().infoDictionary
if let info = infoDict? { // app名称 let appName = info["CFBundleName"] as String! // app版本 let appVersion = info["CFBundleShortVersionString"] // app build版本 let appBuild = info["CFBundleVersion"] as String! }
