How to determine the current iPhone/device model (swift)

let modelName = UIDevice.current.modelName

Simply just extension in the project and you can use it

import UIKit

public extension UIDevice {

    /// pares the deveice name as the standard name
    var modelName: String {

        #if targetEnvironment(simulator)
            let identifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"]!
        #else
            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, value != 0 else { return identifier }
                return identifier + String(UnicodeScalar(UInt8(value)))
            }
        #endif

        switch identifier {
        case "iPod5,1":                                 return "iPod Touch 5"
        case "iPod7,1":                                 return "iPod Touch 6"
        case "iPod9,1":                                 return "iPod touch (7th generation)"
        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"…
