DeviceType — A Swift Helper
A series of helpers and extensions for identifying what device is interacting with your app.
The Problem
It’s not straight forward to identify exactly what device is running your app. I’m working on an update for Role, and I need to be able to split some code depending on whether the device running it is an iPod Touch, an iPhone 4s, or an iPhone 5 or later.
The Solution
I’ve created a helper class called DeviceType, along with two extensions: UIDevice+DeviceType and UIViewController+DeviceType. You can find them and a sample project at the GitHub repo below.
The main usage is the ability to make a call similar to the following:
if UIDevice.currentDevice().deviceType == .iPhone6Plus {
// Some iPhone 6 Plus specific logic...
}I also added a few view helpers for estimating the device based off of the view’s frame size:
if self.isIPhone5sSize {
// Some iPhone 5s specific view logic...
}These methods and extensions have already helped me separate out logic and special cases within my own projects, and I hope they can do the same for others. Feel free to let me know your thoughts here, tweet me @ianhirschfeld, or even contribute to the repo!
