Question 1

How to customize the overlay colors in Mandoline?

Accepted Answer

Use mutable properties like selectedOverlayColor and dotColor on the PickerView instance. For example, set pickerView.selectedOverlayColor = .blue to change the border color, as detailed in the README's optional properties section.

Question 2

Mandoline vs UIPickerView: which is better for iOS?

Accepted Answer

Mandoline offers smoother scrolling, haptic feedback, and more UI customization via UICollectionView, but it's optimized for medium collections. UIPickerView is built-in, simpler for basic picks, but less flexible. Choose Mandoline for premium tactile experiences.

Question 3

Does Mandoline work with SwiftUI?

Accepted Answer

No, Mandoline is built on UIKit and UICollectionView, so it requires UIKit integration. You can use it in SwiftUI via UIViewRepresentable, but it's not native and might need extra setup for bridging.

Question 4

How to handle cell selection events in Mandoline?

Accepted Answer

Implement the PickerViewDelegate's collectionView(_:didSelectItemAt:) method. This optional delegate function is called when a cell is selected, allowing you to respond to user interactions, similar to standard UICollectionView.

Question 5

Is Mandoline good for date pickers?

Accepted Answer

Yes, it's well-suited for date pickers or any selection interface requiring smooth scrolling, as shown in the Blue Apron meal rescheduler example. Customize cells to display dates and use the Selectable protocol for availability.

Question 6

Can I use Mandoline with large datasets?

Accepted Answer

The README warns it's optimized for medium-sized collections. For large datasets, performance might suffer; consider strategies like virtualizing cells or adjusting cellSize, but it's not ideal out-of-the-box.
