Hi everyone,
I'm having a hard time solving my issue. I have a VStack with a ForEach loop that displays (Core)data info. In that ForEach loop I have a View that has a tap gesture (to open a sheet to edit the entity) and a contextMenu (to allow users to delete the selected entity). The sheet is at the VStack (parent of ForEach) level.
VStack() {
ForEach(customModels) { customModel in
VStack() {
Text(customModel.title)
}
.frame(minWidth: 0, maxWidth: .infinity)
.onTapGesture(perform: {
selectedCustomModel = customModel
})
.contextMenu {
Button {
customViewModel.deleteModel(customModel)
} label: {
Label("Delete", systemImage: "trash")
}
}
}
}
.sheet(item: $selectedCustomModel) { selectedCustomModel in
EditCustomView(customModel: selectedCustomModel)
}
If I long press on one of my "child" view the contextMenu appears, if I dismiss that contextMenu by tapping on another child view, then it triggers the "onTapGesture" (which seems fair), and a warning pops in the console :
Attempt to present <_TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView_: 0x7f90939e05b0> on [...] which is already presenting <_UIContextMenuActionsOnlyViewController: 0x7f9093983bd0>.
The problem is at that point any tap on a child view does not work, the onTapGesture is like "dead" I have to tap like 5 or 10 times to to make the edit sheet appears...
Is this a bug or do you see something bad in my implementation ?
Thank you
Jim

Hi everyone,
I'm having a hard time figuring out why the code below results in weird behaviour with the ScrollView.
Code :
struct MainView: View {
@State var strings: [String] = ["A", "B", "C", "D", "E"]
@State var ints: [Int] = Array(1...300)
@State var selectedInt: Int?
var body: some View {
ZStack {
ScrollView {
VStack {
ForEach(strings, id: \.self) { string in
VStack {
HStack {
Text(string)
Spacer()
}
LazyVGrid(columns: [GridItem(.flexible()), GridItem(.flexible()), GridItem(.flexible())]) {
ForEach(ints, id: \.self) { int in
VStack {
Text(String(int))
Spacer()
}
.frame(minWidth: 0, maxWidth: .infinity)
.frame(height: 200)
.background(
RoundedRectangle(cornerRadius: 5)
.fill(int % 2 == 0 ? .orange : .green)
)
.onTapGesture {
self.selectedInt = int
}
}
}
}
}
}
.padding()
}
if let selectedInt {
VStack {
Spacer()
Text(String(selectedInt))
Spacer()
Button {
self.selectedInt = nil
} label: {
Image(systemName: "x.circle")
.resizable()
.scaledToFit()
.frame(width: 30)
}
}
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
}
}
}
}
Issue: Everything is working fine until I scroll to the 3rd or 4th string (after half the full "list" for example) and use the onTapGesture, then the ScrollView goes crazy and goes up for a reason I don't understand (just at the moment I tap the element).
Do I miss something or is this just a bug ?
Thank you for your help :)
Regards
Jim
