How to Create Two Buttons Side by Side in SwiftUI Without a Gap

In the world of mobile application development, creating a seamless user experience is key. One common requirement is to position two buttons side by side without any unwanted space between them. This may seem like a minor detail, but achieving that perfect alignment can enhance the overall aesthetic of your app.

In this post, we will address a specific issue faced by developers using SwiftUI, where two buttons in an HStack appear to have a gap between them. We'll help you understand this problem and provide a straightforward solution.

The Problem: Unwanted Space Between Buttons

Imagine you've created two buttons in a SwiftUI view, intending for them to sit right next to each other. However, after running your code, you notice a space between the two buttons that you didn't want.

Here’s the code snippet that demonstrates this issue:

In this code, despite specifying the layout with frames and intending to have the buttons sit snugly next to each other, a gap might still appear due to default spacing applied to HStack.

The Solution: Removing the Space

To fix this issue and achieve the desired alignment, you simply need to specify that there should be no spacing in your HStack. This can be done by passing a spacing parameter with a value of 0 to the HStack initializer.

Updated Code

Here's the updated code snippet with the solution:

Explanation of Changes

HStack(spacing: 0): By setting spacing: 0, you instruct SwiftUI not to add any space between the views inside the HStack. This results in the two buttons sitting directly adjacent to each other.

No Additional Padding: Including .padding(0) at the end ensures that there are no extra spaces added due to padding.

Conclusion

Creating a user-friendly interface is all about attention to detail. By removing the default spacing in an HStack, you can place your buttons exactly where you want them, enhancing your application's overall user experience. Using this simple adjustment, you can create sleek and professional-looking designs in SwiftUI.

Now that you have this solution, give it a try in your SwiftUI application, and see how much of a difference it makes! Happy coding!
