NavigationLink on SwiftUI pushes view twice
I'm sure that Part
conforms to Identifiable
protocol and has id
property.
The destination of the NavigationLink
is presented multiple times because you have multiple instances of Part
that have the exact same identity id
in the forEach
loop.
Just make sure that each instance of Part
has a unique id
and everything will work as expected.
I solved this by setting the NavigationLink's tag to the unique id of the model item.
Assuming you have an id for your imageRef, ReferenceImage class.
var part: Part
var body: some View {
HStack(spacing: 8.0) {
ForEach(part.getReference()) { (imageRef: ReferenceImage) in
ZStack(alignment: .topTrailing) {
Image(uiImage: imageRef.getUIImage())
.resizable()
.frame(width: 90, height: 90)
.cornerRadius(6)
NavigationLink(destination: ReferenceARSwiftUIView(currentImage: imageRef.getUIImage()), tag: imageRef.id) {
EmptyView()
.frame(width: 90, height: 90)
}
}
}.animation(.interpolatingSpring(stiffness: 0.5, damping: 0.5))
NavigationLink(destination: ReferenceARSwiftUIView(currentImage: imageRef.getUIImage()), tag: imageRef.id)
