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.

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. You can even use Previews with UIKit 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 was created as a port of Brandon Williams and Stephen Celis in Playgrounds for the Kickstarter iOS app and further explained in PointFree to iOS. Make sure to check their site out!

• Inspect your app in multiple device sizes
• Switch orientations
• Test all font sizes
• Universal (iPhone & iPad)

To run the demo project, clone the repo and run Sizes target.

Edit your Podfile and specify the dependency:

pod 'Sizes'

Edit your Cartfile and specify the dependency:

github "marcosgriselli/Sizes"

Sizes require you to use Auto Layout in order to update the UI correctly with each change.

For font updates you'll need to use Dynamic Type.

Programmatically:

let label = UILabel()
label.font = UIFont.preferredFont(forTextStyle: .headline, compatibleWith: traitCollection)
label.adjustsFontForContentSizeCategory = true

IB/Storyboard:

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.

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
}

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. You can check a longer video implementation and some of the use cases of Sizes in this tweet
