@State private var isErrorPresented = false

let jaimages = ["ja1", "ja2", "ja3"]

TabView(selection: $selectedImage) {

Image(image)

var anaglyphMaterial = try await ShaderGraphMaterial(named: "/AnaglyphMaterial", from: "Scene.usda", in: realityKitContentBundle)

try anaglyphMaterial.setParameter(name: "inputImage", value: .textureResource(textureResource))
let entity = Entity()
let model = ModelComponent(mesh: .generatePlane(width: 0.5, height: 0.3), materials: [anaglyphMaterial])
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) {
case (...0, -30...30):
withAnimation {
selectedImage += 1
if selectedImage > jaimages.count - 1 {
selectedImage = 0

case (0..., -30...30):
withAnimation {
selectedImage -= 1
if selectedImage < 0 {
selectedImage = jaimages.count - 1
}
}
case (-100...100, ...0): print("up swipe")
case (-100...100, 0...): print("down swipe")
default: print("default")

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