When working with Swift  you can use the enum UIUserInterfaceIdiom  defined as  enum UIUserInterfaceIdiom   Int       case unspecified          case phone    iPhone and iPod touch style UI     case pad      iPad style UI  also includes macOS Catalyst     So you can use it as  UIDevice current userInterfaceIdiom     pad UIDevice current userInterfaceIdiom     phone UIDevice current userInterfaceIdiom     unspecified  Or with a Switch statement      switch UIDevice current userInterfaceIdiom       case  phone             It s an iPhone     case  pad             It s an iPad  or macOS Catalyst         unknown default             Uh  oh  What could it be         UI USER INTERFACE IDIOM   is an Objective-C macro  which is defined as   define UI USER INTERFACE IDIOM        UIDevice currentDevice  respondsToSelector  selector userInterfaceIdiom         UIDevice currentDevice  userInterfaceIdiom      UIUserInterfaceIdiomPhone   Also  note that even when working with Objective-C  the UI USER INTERFACE IDIOM   macro is only required when targeting iOS 3 2 and below  When deploying to iOS 3 2 and up  you can use  UIDevice userInterfaceIdiom  directly

Made a couple of additions to the above answers so that you get returned a type instead of string value    I figured that this is primarily going to be used for UI adjustments so I didn t think it relevant to include all the sub models i e  iPhone 5s but this could be easily extended by adding in model tests to the isDevice Array  Tested working in Swift 3 1 Xcode 8 3 2 with physical and simulator devices  Implementation   UIDevice whichDevice    public enum SVNDevice     case isiPhone4  isIphone5  isIphone6or7  isIphone6por7p  isIphone  isIpad  isIpadPro    extension UIDevice     class func whichDevice   - gt  SVNDevice        let isDevice      comparision  Array lt  Bool  SVNDevice  gt   - gt  SVNDevice  in       var device  SVNDevice        comparision forEach           device    0 0    0 1   device                return device            return isDevice          UIDevice current userInterfaceIdiom     phone  amp  amp  ScreenSize SCREEN MAX LENGTH  lt  568 0  SVNDevice isiPhone4          UIDevice current userInterfaceIdiom     phone  amp  amp  ScreenSize SCREEN MAX LENGTH    568 0  SVNDevice isIphone5          UIDevice current userInterfaceIdiom     phone  amp  amp  ScreenSize SCREEN MAX LENGTH    667 0  SVNDevice isIphone6or7          UIDevice current userInterfaceIdiom     phone  amp  amp  ScreenSize SCREEN MAX LENGTH    736 0  SVNDevice isIphone6por7p          UIDevice current userInterfaceIdiom     pad  amp  amp  ScreenSize SCREEN MAX LENGTH    1024 0  SVNDevice isIpad          UIDevice current userInterfaceIdiom     pad  amp  amp  ScreenSize SCREEN MAX LENGTH    1366 0  SVNDevice isIpadPro             private struct ScreenSize     static let SCREEN WIDTH           UIScreen main bounds size width   static let SCREEN HEIGHT          UIScreen main bounds size height   static let SCREEN MAX LENGTH      max ScreenSize SCREEN WIDTH  ScreenSize SCREEN HEIGHT    static let SCREEN MIN LENGTH      min ScreenSize SCREEN WIDTH  ScreenSize SCREEN HEIGHT      I ve created a framework called SVNBootstaper which includes this and some other helper protocols  it s public and available through Carthage

FYI  I have used UI USER INTERFACE IDIOM   for my app written in Swift  The app can be compiled well with XCode 6 3 1 without any warning on that command  runs well on Simulator  with any selected devices  and on all my real devices  iPhone  iPad  with iOS versions from 7 1 to 8 3   However  the app crashed on Apple reviewers  devices  and was refused   That took me few days to detect the problem with few more re-uploads to iTunes Connect   Now I use UIDevice currentDevice   userInterfaceIdiom instead and my app can survive from such crashes

Try adding an extension like this       public extension UIDevice        var modelName  String           var systemInfo   utsname           uname  amp 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   EDIT For simulator  you can try a solution here
