Question 1

How to use AHDownloadButton in SwiftUI?

Accepted Answer

AHDownloadButton is a UIKit component, so you need to wrap it in a UIViewRepresentable to integrate it into SwiftUI. This involves creating a coordinator to handle delegate callbacks and updating the button state based on SwiftUI data bindings.

Question 2

AHDownloadButton vs building a custom download button from scratch?

Accepted Answer

AHDownloadButton saves significant time by providing a polished, App Store-like button with animations out-of-the-box, but if you need unique states, shapes, or tighter control over performance, a custom implementation might be better despite the higher initial effort.

Question 3

How to handle download errors with AHDownloadButton?

Accepted Answer

Since AHDownloadButton lacks an error state, you must manage errors externally—for example, by resetting the button to the startDownload state and showing an alert. The progress property can be set to 0, but visual feedback for failures isn't built-in.

Question 4

Can AHDownloadButton be used in Objective-C projects?

Accepted Answer

No, AHDownloadButton is written in Swift 5.0+ and relies on Swift-only features like enums with associated values, making it incompatible with Objective-C. You'd need to bridge it or find an alternative library.

Question 5

How to customize the progress circle color in AHDownloadButton?

Accepted Answer

Use the downloadingButtonHighlightedProgressCircleColor and downloadingButtonNonhighlightedProgressCircleColor properties from the 'Customisation' section to set colors for the progress circle in highlighted and normal states, respectively, with examples provided in the README.

Question 6

Is AHDownloadButton accessible for VoiceOver users?

Accepted Answer

The README doesn't mention accessibility features, so you'll need to add VoiceOver labels and hints manually by setting accessibility properties on the button instance after customization to ensure it works with screen readers.
