Question 1

How do I change the mark colors in HorizontalDial?

Accepted Answer

Use the markColor and centerMarkColor properties documented in the README. For example, set markColor to UIColor.red to make all marks red, and adjust centerMarkColor for the center indicator to differentiate it visually.

Question 2

HorizontalDial vs UISlider: which should I use for a simple value picker?

Accepted Answer

HorizontalDial is better for visually rich, scroll-based interactions like Instagram's dial, offering smoother scrolling and custom marks. UISlider is more standard, accessible, and integrated with iOS defaults, so choose based on design flair versus simplicity.

Question 3

Can I use HorizontalDial in a SwiftUI project?

Accepted Answer

Yes, but indirectly via UIViewRepresentable since it's a UIKit component. This adds wrapping complexity and may not feel seamless compared to native SwiftUI solutions, so consider if the trade-off is worth it for your app.

Question 4

How to handle value changes when the user scrolls?

Accepted Answer

Implement the horizontalDialDidValueChanged protocol method as a delegate. This callback provides the updated HorizontalDial instance, letting you read the value property and sync it with your app's state in real-time.

Question 5

What's the best way to install HorizontalDial without CocoaPods?

Accepted Answer

Drag the HorizontalDial.swift file into your Xcode project manually, as mentioned in the README. This avoids dependency managers but requires you to handle updates and versioning yourself, which can be error-prone.

Question 6

Does HorizontalDial support accessibility features like VoiceOver?

Accepted Answer

The README doesn't mention accessibility, so you'll likely need to add custom accessibility labels and traits programmatically. This extra work means it's not ideal for apps where accessibility is a top priority out of the box.
