Apple Worldwide Developers Conference (WWDC), 2019 brought a lot of new features, technologies and a new version of iOS (iOS 13) as well. It was organized from 3rd to 7th June 2019. During this developers’ conference, it was announced that Dark Mode will be available on iOS 13 and later versions. 

What you will learn in this blog:

  • What iOS Dark Mode is and what it does
  • The benefits of using Dark Mode
  • Important considerations while implementing Dark Mode in an app
  • Customizing the color scheme for your iOS application for different themes – light and dark mode.

What is iOS Dark Mode? What does it do?

Dark Mode is a dark system-wide appearance that uses a darker color palette for all screens, views, menus, and controls. Basically, like Android Dark Mode, it changes a bright theme to a darker one. It also maintains vibrancy and contrast to make foreground content stand out against a darker background.

Benefits of Dark Mode

  • It is most helpful when the surrounding is dark. This puts less strain on eyes as compared to light mode. 
  • You can choose Dark Mode as your default interface style.
  • You can also use Settings to make your device switch to Dark Mode automatically when ambient light is low.
  • Dark Mode supports all accessibility features.
  • Using Dark Mode on OLED iPhone models like iPhone X, XS, XS Max may also improve battery life. This is because black pixels in an OLED panel actually switch off and conserve battery power.
  • Bonus: Dark Mode looks really cool

As announced by Apple during the conference, Apple’s preinstalled apps like Notes, News, TV, Music, Reminders, Mail, and others will already have it.

However, developers will be able to use Apple’s new tools to add dark mode to their apps. Being an iPhone app development company, we had a lot of our clients wanting to integrate this feature to their iOS apps. 

Our proficient iPhone app developers decided to help other developers by explaining the feature with a simple example. Before we see how to add this feature, let us know which are the important considerations that one should keep in mind during feature integration.

Considerations for iPhone Dark Mode while implementing in an app

Put the focus on content: Make sure that content stands out and surrounding UI recedes into the background. The purpose of the Dark Mode is to put the focus on the content areas of the interface.

Test for both- light and dark appearances: Check how the interface looks in both appearances. You may need to adjust designs to accommodate each one as designs working well in one appearance might not work in another.

Test with changes in contrast and transparency: You must test the content when Increase Contrast and Reduce Transparency is turned on. Make sure that content is distinct in Dark Mode when you adjust contrast and transparency settings.

Now that you are clear about considerations, let’s customize color scheme for your iOS application for different themes.
