Sometimes, you may want to create a custom component, even if there is a similar one in UIKit because you want to style it in a way that the default one won't let you. That's fine, just take into account that you'll need to make it accessible.

The .accessibilityElement(children: ) modifier with the .ignore argument does a similar thing to set the container view to be an accessibility element in UIKit. It is the default argument, so you can just say .accessibilityElement(). Because of this, you'll need to use other modifiers to make it accessible and manually configure an accessibility label and value, traits... when necessary. https://developer.apple.com/documentation/swiftui/view/accessibilityelement(children:) https://developer.apple.com/documentation/swiftui/accessibilitychildbehavior/ignore
Images can automatically scale for accessibility content size categories, by setting the adjustsImageSizeForAccessibilityContentSizeCategory property to true, for any UIImageView you'd like to get its size adjusted. https://developer.apple.com/documentation/uikit/uiaccessibilitycontentsizecategoryimageadjusting/adjustsimagesizeforaccessibilitycontentsizecategory
With accessibilityRepresentation(representation:), you can create a custom component and it can be perceived by assistive technologies as the view you pass as representation. No need to manually configure accessibility attributes. It is one of the most interesting additions to SwiftUI to help you develop accessible UI components. If your custom component behaves similarly to a native one, this is the way to go. https://developer.apple.com/documentation/swiftui/view/accessibilityrepresentation(representation:)
