[ios] How to determine the current iPhone/device model?

Swift 5.3, both device & simulator updated to end of 2020

with the new iPhone 12 Mini, iPhone 12, iPhone 12 Pro , iPhone 12 Pro Max and the new latest iPad Air 9.7'' 4th gen, iPad 9.7'' 8th gen, iPad Pro 12.9'' 4th gen and iPad Pro 11'' 2nd gen. (new update with also 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)

            }
        }
        return model

    return Model.unrecognized
  }
}

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