Has anybody tried this? I haven't gotten it to work. Did Apple break this? I can get a list Item to drag but I don't get the green circle with the + sign and it won't drop. I put print() statements in the .dropDestination closures and the print0 in the first closure for processing the dragged item(s) doesn't fire. The one in the isTargeted does fire when the drag goes over the drop destination.

I just checked the project and rebuilt it with the latest Xcode and iOS 17 and the project is working. Are you following my project exactly, or trying to implement it into your existing code?
@chuckincharlie9 ай бұрын
@@seanallen Thanks for checking it for me. I'm kind of doing both. I have an app I'm building that uses AppleMusic and I'm building a playlist builder for it. A list of songs on one side and the playlist(an empty list initially) on the other side and I want to drag songs onto the playlist. I built a simplified separate project to implement basically what you're doing for quick reference on other projects but couldn't get it to work. That project uses the two lists though which I think is the problem. Someone on Reddit iOSProgramming said to use onDrag and onDrop when working with lists. Interesting thing is I threw print() statements into both halves of the .dropDestination and the first print() in the top section doesn't fire but the second Print() in the isTargeted does. I also was primarily building for iPad and got an error off the drag (Found no UIEvent for backing event of type: 11; contextId: 0xaabebfd) and I tried it on iPhone and didn't get the error but it still didn't work. Added primarily in case this might help someone else.

@@seanallen I have the same problem - but in my case it does not work at all. Step to reproduce: - download Xcode project from the link in the description - try to drag and drop using Preview - nothing happens, it just does not respond to my gestures - build on my iPhone 12 mini and try to drag and drop - still nothing happens, it just does not respond to my gestures I have Xcode Version 15.0.1 (15A507), Swift version 5.9, macOS version 14.1.1 Same problem goes for any tutorial projects using draggable/dropDestination and also for my own code

+1 on this. Also trying to use this with on a Mac target and it doesn't seem to be letting me use my own models. Works fine with [String] but not with custom models. To be more precise, I can drag the custom views fine, but cannot drop them in the specified drop destination. I am not using the previews, as they don't work for the drag and drop functionality at the time of this message. Pretty confident I've set up everything properly, including setting up the custom UTType in the project's info.plist. Will continue investigating.

@garya1809Ай бұрын
Hopefully not too nitpicky but if you redo this video or do something similar in the future, can you call it something other than task? a Task class in C# or like a Task/FutureTask in Java mean something very different than a chore/todo and I'm sure other languages use Task as like a promise/future event, and while I watched this I kept saying stuff "but where is the task callback?" or "wait is the variable inProgressTask for a cancellable promise?" IDK - just some random thoughts.

Sean, thank you very much. I have a question which goes deeper. extension ImageDocumentLayer: Transferable { static var transferRepresentation: some TransferRepresentation { DataRepresentation(contentType: .layer) { layer in layer.data() } importing: { data in try ImageDocumentLayer(data: data) } DataRepresentation(exportedContentType: .png) { layer in layer.pngData() } } } This is code is on Apple Official Doc. This transferRepresentation consists of two DataRepresentation. They are async throw functions. Why transferRepresentation itself doesn't have the key word async or throws?

I believe this will still work, you just need to add the logic when the item is dropped to re-order the items in each array

I believe the template no longer works out of the box. Adding `.draggable(task)` in step one allows the object to pop up on hold click, but it cannot be dragged at all--it is stuck in place (it cannot even be dragged to a `.dropDestination`, which is added later). There is no build error. Can someone explain why this behavior is occurring? Someone else in the comments is also experiencing this.

Hey Sean, just a quick question: it is already been 4 years since SwiftUI has been released. My question is, is it still the case that UIKIT is more advanced than SwiftUI? For Rex maple, changing a placeholder holder in SwiftUI vs UIKIT? Or is SwiftUI now just as advanced as UIKIT?
@seanallen Жыл бұрын
If you need to do VERY HIGHLY customized UI, then UIKit is still the way to go. You have a lot more control. That being said, SwiftUI gets better and better each year and is Apple's future.
