How do I support dynamic type and font scaling in SwiftUI/UIKit?

Dynamic type and font scaling are crucial for ensuring accessibility and a better user experience in both SwiftUI and UIKit. This guide discusses how to implement dynamic type support in your applications, allowing text to adjust based on the user's preferred reading size.

Supporting Dynamic Type in UIKit

In UIKit, you can support dynamic type by using the system font with the appropriate text style. Here's a simple example:

UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem]; button.titleLabel.font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody]; [button setTitle:@"Dynamic Text Button" forState:UIControlStateNormal]; [button sizeToFit];

Supporting Dynamic Type in SwiftUI

In SwiftUI, you can easily support dynamic type by using the `.font()` modifier with the `.body` style or any appropriate text style:

struct ContentView: View { var body: some View { Text("Dynamic Text Label") .font(.body) // This will scale with the user's preferred font size } }

Both methods ensure that your text scales according to the user's preferences, improving accessibility.
