entity.components.set(model)
content.add(entity)
}
}
// .tabViewStyle(.page)
.gesture(DragGesture(minimumDistance: 3.0, coordinateSpace: .local)
.onEnded { value in
print(value.translation)
switch(value.translation.width, value.translation.height) {

selectedImage = jaimages.count - 1

case (-100...100, ...0): print("up swipe")
case (-100...100, 0...): print("down swipe")

Candidate has partially matching parameter list ([(PartialRangeFrom.Element, String)], id: KeyPath<(PartialRangeFrom.Element, String), Int>, content: @escaping ((PartialRangeFrom.Element, String)) -> _)
