In the previous chapter, you learned about implementing accessibility in your app. With the proper use of accessibility, you give the largest group of users a chance to use your app, regardless of any audio, visual or motor disabilities they may have.
Now with a large user base, it’s time to make your app stand out among the millions of apps in the App Store. There are different ways to do this. Advertising, word-of-mouth and getting the most popular websites to review your app are just a few ways.
Before you do any of that, it’s important to make your app look unique. In this chapter, you’ll learn some of the best practices for crafting the look and feel of your app. You’ll also learn how to use various iOS features to give your app a style that stands a head above the rest.
Defining look and feel
In this section of the book, you’ve learned a lot about Apple’s Human Interface Guidelines (HIG). This chapter is no different. Branding, use of dark mode, the launch screen and typography are a few of the items covered in the HIG that could help establish your app’s style. This style is usually referred to as your app’s look and feel.
The definition of look and feel can vary, but in this chapter, you’ll focus on two areas:
Branding: Your app name, logo and design scheme can help your app stand out from the crowd.
Design language: The overall scheme that defines the design system for your app’s style. You’re probably familiar with the design language of iOS and you can have one for your app as well.
You may have noticed an overlap between those two areas. Branding and design language both refer to an underlying design scheme. Your design scheme is more evident in your app logo or launch screen. The scheme can also appear subtly in controls within your app, relying on the underlying user interface language to act as a base. Here, the scheme acts as a skin on existing controls.
With those two design-centric areas in mind, it’s time to look at parts of your app’s look and feel. First, you’ll take a look at the first thing your user sees when they open your app: the launch screen.
Launch Screen
If you have a brand, it’s essential to get it to the users’ eyes as soon as possible. Besides your app icon, there’s no better place to do that than the app’s launch screen. The HIG contains important guidance when it comes to the launch screen:

Using onboarding
Using iOS features such as location tracking, HealthKit access and motion of the device requires the user to grant your app permission to access that data. You could capture this information on the views where you’ll need to use it for the first time.

Crafting the finer details
Your launch screen and onboarding focus more on the branding aspect of your app. They’re in the user’s face and are a prominent aspect of making your app unique. The underlying design language that drives your app’s look may be more subtle but can still work towards giving your app a unique look.
Almost all apps have text to convey information to users. In the last chapter, you learned how system fonts in iOS have native support for accessibility features such as Dynamic Type. In addition, system fonts:

Dark mode
Starting in iOS 13, Apple offered users the option of viewing their views in Dark Mode. Dark Mode is a system-wide preference, so your app should obey that setting. You have to ensure that your app looks good in both light and dark modes.

Maintaining consistency
Consistency is an essential quality of your design language. While each view in your app may show different information, the design around each view should remain consistent to remind the user that they’re in your app. They’ll associate your unique look and feel with using your app.

Internationalization and localization
You might not associate look and feel with internationalization and localization. Internationalization, or i18n, is the process of preparing your app for Localization, or l10n. Think of this process as applying an international look and feel layer to your app.

Making a localizable Strings file
Before localizing the project, add Localizable.strings to the project. Right-click the project, select New File and choose Strings File:
To properly test your localization, you’ll need to update your project’s scheme. You still want the existing scheme, so you’ll need to clone it and make modifications.
Branding and your app’s design language are the major components of your app’s look and feel.
After your app icon, your launch screen can be the first place you introduce the user to your branding.
Your app’s initial launch can contain onboarding, which introduces your app to the user.
Onboarding should be brief but informative.
Fonts help define the text-based portion of your app’s look and feel.
Fonts, especially custom ones, should be accessible and easy to read.
Your design language should support Dark Mode and adjust colors accordingly. Color Sets are useful when adapting your app for Dark Mode.
Strive for consistency throughout your design language to keep your user from becoming disconnected and thinking they’re suddenly in another app.
Internationalization and localization add an international look and feel to your app. Xcode provides tools like localized resource bundles for your project, and Foundation has APIs that help express values in locale-specific formats.
