I made this "pure Swift" extension on UIDevice.

This version works in Swift 2 or higherIf you use an earlier version please use an older version of my answer.

If you are looking for a more elegant solution you can use my µ-framework DeviceKit published on GitHub (also available via CocoaPods, Carthage and Swift Package Manager).

Here's the code:

import UIKitpublic extension UIDevice {    static let 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, value != 0 else { return identifier }            return identifier + String(UnicodeScalar(UInt8(value)))        }        func mapToDevice(identifier: String) -> String { // swiftlint:disable:this cyclomatic_complexity            #if os(iOS)            switch identifier {            case "iPod5,1":                                       return "iPod touch (5th generation)"

You call it like this:

let modelName = UIDevice.modelName

For real devices it returns e.g. "iPad Pro 9.7 Inch", for simulators it returns "Simulator " + Simulator identifier, e.g. "Simulator iPad Pro 9.7 Inch"

Swift 5.4, both device & simulator updated to 2021

with the last: iPhone 13 (all models), iPad Pro (11-inch) (3rd generation), iPad Pro (12.9-inch) (5th generation) and Apple TV 4K (2nd generation) , (updates also for all iPods, Apple Watches and Apple TVs)

This method detects the correct model even if it's a simulator. (The exact name for the simulator device model running in your simulator)

Usage:You can simply get the device model with:

let deviceType = UIDevice().type

or print the exact string with:

print("Running on: \(UIDevice().type)")Output -> "iPhone X"

Another example with cases:

var myDefaultFontSize: CGFloat = 26.0switch UIDevice().type {    case .iPhoneSE, .iPhone5, .iPhone5S: print("default value")    case .iPhone6, .iPhone7, .iPhone8, .iPhone6S, .iPhoneX: myDefaultFontSize += 4    default: break}

P.S.: I've made a little new asyncronous experiment here without static device list

This Swift 3.0 example returns the current device model as an enum constant (to avoid direct comparisons to string literals). The enum's raw value is a String containing the human-readable iOS device name. Since it is Swift, the list of recognized devices only includes models recent enough to support iOS releases that include Swift. The following usage example utilizes the implementation at the end of this answer:

    switch UIDevice().type {    case .iPhone5:              print("No TouchID sensor")    case .iPhone5S:              fallthrough    case .iPhone6:              fallthrough    case .iPhone6plus:              fallthrough    case .iPad_Pro9_7:              fallthrough    case .iPad_Pro12_9:              fallthrough    case .iPhone7:              fallthrough    case .iPhone7plus:              print("Put your thumb on the " +                      UIDevice().type.rawValue + " TouchID sensor")    case .unrecognized:              print("Device model unrecognized");    default:              print(UIDevice().type.rawValue + " not supported by this app");    }

Your app should be kept up-to-date for new device releases and also when Apple adds new models for the same device family. For example, iPhone3,1 iPhone3,2 iPhone3,4 are all "iPhone 4". Avoid writing code that doesn't account for new models, so your algorithms don't unexpectedly fail to configure or respond to a new device. You can refer to this maintained list of iOS Device Model #'s to update your app at strategic times.

iOS includes device-independent interfaces to detect hardware capabilities and parameters such as screen size. The generalized interfaces Apple provides are usually the safest, best supported mechanisms to dynamically adapt an app's behavior to different hardware. Nevertheless, the following code can be useful for prototyping, debugging, testing, or any time code needs to target a specific device family. This technique can also be useful to describe the current device by its common/publicly recognized name.
