Maximizing Your SwiftUI App's Window: How to Set the Frame for Fullscreen on macOS

Creating a great user experience for your macOS applications using SwiftUI can be quite challenging. One common issue that developers encounter is setting the application window to open at its maximum screen space. This means ensuring that the window is as large as possible when it is opened, accommodating the entire screen area of the user's device. Many developers have experienced problems where their app windows open at the minimum specified size rather than utilizing available screen real estate effectively.

The Problem

When using SwiftUI, you might attempt to set your app window's frame as follows:

While this code tries to allow for a flexible window size, one frequent complaint is that the application still opens at the minimum specified width and height. This results in a less-than-ideal user experience, as the window size does not take full advantage of the space available on the screen.

The Solution: Use System Screen Dimensions

To resolve the issue of your SwiftUI app not opening at the desired size, consider utilizing the actual dimensions of the user's screen. Instead of relying on arbitrary minimum sizes, you can make use of NSScreen.main?.frame.width and NSScreen.main?.frame.height to set your minimum frame dynamically based on the current screen size.

Implementing the Solution

Here’s how you can set your app window's frame to open at maximum available screen space:

How It Works

Dynamic Sizing: The NSScreen.main?.frame.width and NSScreen.main?.frame.height functions fetch the current screen's dimensions automatically, making sure your application window is positioned to fully utilize the user's display.

Adaptability: This solution accommodates various screen sizes, ensuring that your application looks great on both smaller laptops and larger external monitors.

Considerations

SwiftUI Compatibility: This approach works well in SwiftUI 3.0 and has been confirmed to function smoothly in macOS 12.1 beta and likely later versions, providing confidence in its reliability.

User Experience: Always consider the layout and overall experience while designing your app window. A well-sized window contributes to user satisfaction and makes your application feel professional.

Conclusion

By implementing the simple yet effective solution of utilizing the screen's dimensions for your SwiftUI app’s frame, you ensure that your window opens to effectively occupy the maximum space available. This change not only enhances functionality but also provides a streamlined experience for your users.
