Im making an app that uses drag&drop but, it doesn't work.
This is made with Swift Playground.
If you can find a solution, please let me know.
Here is the code.
//MARK: Drop Area
@ViewBuilder
func DropAera()->some View{
VStack(spacing: 12){
ForEach($rows,id:\.self){$row in
HStack(spacing: 10){
ForEach($row){$item in
Text(item.value)
.font(.system(size: item.fontSize))
.padding(.vertical,5)
.padding(.horizontal,item.padding)
.opacity(item.isShowing ? 1 : 0)
.background{
RoundedRectangle(cornerRadius: 6, style: .continuous)
.fill(item.isShowing ? .clear : .gray.opacity(0.25))
}
.background{
// If Item is Dropped into Correct Plase
RoundedRectangle(cornerRadius: 6, style: .continuous)
.stroke(.gray)
.opacity(item.isShowing ? 1 : 0)
}
// MARK: Adding Drop Operation
// MARK: Adding Drag Drop Operation
.onDrop(of: [.url], isTargeted: .constant(false)) {
providers in
if let first = providers.first{
let _ = first.loadObject(ofClass: URL.self) {
value,error in
guard let url = value else{return}
if item.id == "\(url)"{
droppedCount += 1
let progress = (droppedCount / CGFloat(characters.count))
withAnimation{
item.isShowing = true
updateShuffledArray(character: item)
self.progress = progress
}
}
else{
//Animating When Wrong text
animateView()
}
}
}
return false
}
}
}
if rows.last != row{
Divider()
}
}
}
}
@ViewBuilder
func DragArea()->some View{
VStack(spacing: 12){
ForEach(shuffledRows,id: \.self){row in
HStack(spacing: 10){
ForEach(row){item in
Text(item.value)
.font(.system(size: item.fontSize))
.padding(.vertical,5)
.padding(.horizontal,item.padding)
.background{
RoundedRectangle(cornerRadius: 6, style: .continuous)
.stroke(.gray)
}
// MARK: Adding Drag Drop Operation
.onDrag{
// Returning ID to find whitch Item is Moving
return .init(contentsOf: URL(string: item.id))!
}
.opacity(item.isShowing ? 0 : 1)
.background{
RoundedRectangle(cornerRadius: 6, style: .continuous)
.fill(item.isShowing ? .gray.opacity(0.25) : .clear)
}
}
}
if shuffledRows.last != row{
Divider()
}
}
}
}
