Here is possible approach - to keep selection during drag. Tested with Xcode 11.4 / iOS 13.4.
@GestureState private var dragOffset = CGSize.zero
@State private var selected: Plant? = nil // << your plant type here
var body: some View {
//Plants Headline
VStack (spacing: 5) {
Text("Plants")
.font(.headline)
.fontWeight(.light)
//HStack for Plants Images
HStack (spacing: 10) {
//For each that loops through all of the plants inside the plant box
ForEach(plantBoxViewModel.plants) { plant in
//Image of the individual plant (obtained via http request to the backend)
Image(base64String: plant.picture)
.resizable()
.clipShape(Circle())
.overlay(Circle().stroke(Color.white, lineWidth: 2))
.offset(x: self.selected == plant ? self.dragOffset.width : 0,
y: self.selected == plant ? self.dragOffset.height : 0)
.animation(.easeInOut)
.aspectRatio(contentMode: .fill)
.frame(width: 70, height: 70)
.gesture(
DragGesture()
.updating(self.$dragOffset, body: { (value, state, transaction) in
if nil == self.selected {
self.selected = plant
}
state = value.translation
}).onEnded { _ in self.selected = nil }
)
}
}
}
}
