[](https://codecov.io/gh/marcosgriselli/Sizes)   Sizes reduces the time it takes to evaluate all of our apps possible device sizes, orientations and font combinations. With Sizes we'll avoid launching all the supported devices simulator, running our app and navigating through each screen manually which not only takes a lot of time but its also highly error prone since we sometimes forget to test one particular combination and we ship a screen with a layout bug to the App Store. ## ⚠️ Sizes deprecation recommendation Xcode 11 introduced Previews which is a fantastic way to quickly validate your UI in multiple scenarios just like Sizes did. If you'd like to know more about Xcode Previews I recommend [this WWDC session](https://developer.apple.com/videos/play/wwdc2019/233/). You can even use [Previews with UIKit](https://nshipster.com/swiftui-previews/) so there's no reason to stick to this library. This library will be deprecated and the repo will be archived in the future. ## 📱 Sizes in action *Recorded on an 10.5 inch iPad Pro* [](https://www.pointfree.co) Sizes was created as a port of [Brandon Williams](https://twitter.com/mbrandonw) and [Stephen Celis](https://twitter.com/stephencelis) in Playgrounds for the [Kickstarter iOS app](https://github.com/kickstarter/ios-oss) and further explained in [PointFree](https://www.pointfree.co) to iOS. Make sure to check their site out! ## 🌟 Features - [x] Inspect your app in multiple device sizes - [x] Switch orientations - [x] Test all font sizes - [x] Universal (iPhone & iPad) ### 💡 Demo To run the demo project, clone the repo and run `Sizes` target. ## 📲 Installation #### Using [CocoaPods](https://cocoapods.org) Edit your `Podfile` and specify the dependency: ```ruby pod 'Sizes' ``` #### Using [Carthage](https://github.com/carthage) Edit your `Cartfile` and specify the dependency: ```bash github "marcosgriselli/Sizes" ``` ## 👩‍💻 How to use ### Preparations Sizes require you to use [Auto Layout]((https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/AutolayoutPG/)) in order to update the UI correctly with each change. For font updates you'll need to use [Dynamic Type](https://developer.apple.com/design/human-interface-guidelines/ios/visual-design/typography/). **Programmatically:** ```swift let label = UILabel() label.font = UIFont.preferredFont(forTextStyle: .headline, compatibleWith: traitCollection) label.adjustsFontForContentSizeCategory = true ``` **IB/Storyboard:** ### Setup I highly recommend you only use this while on `#DEBUG` mode. The best way to setup Sizes is to use the `SizesWindow` as your `AppDelegates'` window. This will automatically make a `SizesViewController` instance contain your apps root view controller and you'll still be able to use code like `UIApplication.shared.windows.first?.rootViewController as? YourInitialCustomViewController` with no issues. ```swift func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { #if DEBUG window = SizesWindow() window?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()! window?.makeKeyAndVisible() #endif return true } ``` ### Usage Shake to display the Sizes configuration UI, then tap on one of the orientation/device options to trigger a change. Or update the Text size slider to navigate through the different font sizes, you'll get the font name as you slide.
