Customizing the Sign In With Apple Button Style Based on Color Scheme in SwiftUI

In today's digital realm, providing a user-friendly interface is crucial, especially in mobile applications. One common interface element seen in many iOS apps is the Sign In With Apple button. However, customizing its appearance based on the user's color scheme can be a bit tricky if you're using SwiftUI. In this guide, we will take a closer look at how to dynamically change the style of the Sign In With Apple button according to the user's current color scheme. Let's dive in!

The Problem

When developing your iOS app using SwiftUI, you might have encountered difficulties in changing the style of the SignInWithAppleButton. The main issue lies in the fact that the button's appearance does not update to reflect changes in the user’s color scheme. This can be frustrating, especially when you're trying to provide a consistent experience for users switching between light and dark modes.

You may find yourself using an @ Environment(.colorScheme) to determine the current scheme, and you could have set a state variable to modify the button's appearance. However, the button's style might not change as expected even though your state variable updates correctly. So, how do we fix this issue?

The Solution

Step 1: Create a Separate View

The first step in resolving this issue is to separate the SignInWithAppleButton into its own dedicated view. This will allow you to manage its properties more effectively. Here’s how to structure your code:

Step 2: Understand the Code

In the code above, we have achieved the following:

Environment Variable: We utilize @ Environment(.colorScheme) to detect the current color scheme set on the user’s device. This allows us to dynamically adjust the interface according to light or dark mode.

Conditional View Logic: The if statement checks the current scheme, and based on that, it chooses the appropriate style for the SignInWithAppleButtonView:

Light Mode: The button is styled as .black.

Dark Mode: The button is styled as .white.

Step 3: Testing the Implementation

After implementing these changes, be sure to test your application in both light and dark mode to ensure that the button's style updates seamlessly. This small adjustment ensures that your Sign In With Apple button is not only functional but also visually appealing in every context.

Conclusion

By restructuring your SwiftUI code to handle the SignInWithAppleButton within its own view and using the environment color scheme appropriately, you can easily ensure that the button's appearance reflects the user's preferences. This not only enhances usability but also aligns your application with Apple’s design principles.

Now you have a clearer understanding of how to tackle the challenge of customizing the Sign In With Apple button style based on the current color scheme. Happy coding!
