| // CustomSwipeActionsSwiftUI | |
| // | |
| // Custom Swipe Actions in Lists are provided by default, however even if you add a title and an icon to the SwipeAction, | |
| // SwiftUI will decide internally which one to you (or both). So you do not have full control on how your swipe action | |
| // button appears... I was implementing a custom swipe action and discovered many pitfalls in the List + SwipeActions | |
| // combination in SwiftUI. Checkout how I solved it with a dragGesture and views on a ScrollView. | |
| // It's a lot of craft to make these custom actions work, so I do not recommend to use such a fancy alternative unless | |
| // you have extremely good reasons since you will loose the capabilities offered by the system to do swipe, drags, | |
| // gestures interactions calculations on its own, and it will cost you on maintenance in the future. |
