Swift: 讀取 iOS 設備的型號/版本資料
 
let dictionary = Bundle.main.infoDictionary!
let app_version = dictionary["CFBundleShortVersionString"] as! String
let app_build = dictionary["CFBundleVersion"] as! String
let app_dDisplayName = dictionary["CFBundleDisplayName"]
        
print("app_dDisplayName = \(app_dDisplayName!)")
print("app_version = \(app_version)")
print("app_build = \(app_build)")

print("UIDevice.current.name = \(UIDevice.current.name)")
print("UIDevice.current.model = \(UIDevice.current.model)")
print("UIDevice.current.systemName = \(UIDevice.current.systemName)")
print("UIDevice.current.systemVersion = \(UIDevice.current.systemVersion)")
print("UIDevice.current.identifierForVendor! = \(UIDevice.current.identifierForVendor!)")


UIDevice.current.identifierForVendor -->    當 app重裝後 identifierForVendor 會變


模擬器 的結果:
app_dDisplayName = helloApp
app_version = 1.0
app_build = 1
UIDevice.current.name = ffmac      (Macbook的名稱)
UIDevice.current.model = iPhone
UIDevice.current.systemName = iOS
UIDevice.current.systemVersion = 11.2
UIDevice.current.identifierForVendor! = E6B52865-0F8E-4773-BF42-E40E2C37F472
 

iPhone 6 的結果:
app_dDisplayName = helloApp
app_version = 1.0
app_build = 1
UIDevice.current.name = _helloiphone
UIDevice.current.model = iPhone
UIDevice.current.systemName = iOS
UIDevice.current.systemVersion = 11.2.6
UIDevice.current.identifierForVendor! = 2057AEC2-91F6-44D4-8D32-36CDFE2638D0



另外,要得知 iOS 的設備型號
參考
https://stackoverflow.com/questions/24059327/detect-current-device-with-ui-user-interface-idiom-in-swift/40083017
let userInterface = UIDevice.current.userInterfaceIdiom

if userInterface == .pad {
    print("iPad")
} else if userInterface == .phone {
    print("iPhone")
} else if userInterface == .carPlay {
    print("CartPlay")
} else if userInterface == .tv {
    print("AppleTV")
}
 
public extension UIDevice {

    var modelName: String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8 where value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

        switch identifier {
        case "iPod5,1":                                 return "iPod Touch 5"
        case "iPod7,1":                                 return "iPod Touch 6"
        case "iPhone3,1", "iPhone3,2", "iPhone3,3":     return "iPhone 4"
        case "iPhone4,1":                               return "iPhone 4s"
        case "iPhone5,1", "iPhone5,2":                  return "iPhone 5"
        case "iPhone5,3", "iPhone5,4":                  return "iPhone 5c"
        case "iPhone6,1", "iPhone6,2":                  return "iPhone 5s"
        case "iPhone7,2":                               return "iPhone 6"
        case "iPhone7,1":                               return "iPhone 6 Plus"
        case "iPhone8,1":                               return "iPhone 6s"
        case "iPhone8,2":                               return "iPhone 6s Plus"
        case "iPhone9,1", "iPhone9,3":                  return "iPhone 7"
        case "iPhone9,2", "iPhone9,4":                  return "iPhone 7 Plus"
        case "iPhone8,4":                               return "iPhone SE"
        case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
        case "iPad3,1", "iPad3,2", "iPad3,3":           return "iPad 3"
        case "iPad3,4", "iPad3,5", "iPad3,6":           return "iPad 4"
        case "iPad4,1", "iPad4,2", "iPad4,3":           return "iPad Air"
        case "iPad5,3", "iPad5,4":                      return "iPad Air 2"
        case "iPad2,5", "iPad2,6", "iPad2,7":           return "iPad Mini"
        case "iPad4,4", "iPad4,5", "iPad4,6":           return "iPad Mini 2"
        case "iPad4,7", "iPad4,8", "iPad4,9":           return "iPad Mini 3"
        case "iPad5,1", "iPad5,2":                      return "iPad Mini 4"
        case "iPad6,3", "iPad6,4", "iPad6,7", "iPad6,8":return "iPad Pro"
        case "AppleTV5,3":                              return "Apple TV"
        case "i386", "x86_64":                          return "Simulator"
        default:                                        return identifier
        }
    }

}


This is how you will use it:

let modelName = UIDevice.currentDevice().modelName



 


另外

if #available(iOS 10.0, *) {  
  // iOS 10.0 (含)以上其它作業系統 執行這裡
            
}  

* 星號 指的是其它作業系統

或這樣寫 
@available(iOS 10.0, OSX 10.10, *)
    func myMethod() {    // iOS 10.0 (含)以上OSX 10.10(含)以上其它作業系統 執行這裡
        ...
    }


或這樣
 @available(iOS 10.0, *)
    func myMethod() {
        ...
    }

還有
@available(swift 3.0.2)
struct MyStruct {
    // struct definition
}


if #available(tvOS 1.0, *) {  
                  
}
  
if #available(watchOS 1.0, *) {  
                  
}

if #available(OSX 10.11, *) { 

}
