SwiftUI List onTapGesture covered NavigationLink - swift

Question

I want to hide keyboard when tapped the list background, but onTapGesture will cover NavigationLink. Is this a bug or have a better solution?
struct ContentView: View {
#State var text: String = ""
var body: some View {
NavigationView {
List {
NavigationLink("NextPage", destination: Text("Page"))
TextField("Placeholder", text: $text)
}
.onTapGesture {
// hide keyboard...
UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)
}
}
}
}
Thanks!
update
Thanks to asperi, and I found an alternative way: just put it in section header. As for style, we should create a custom ButtonStyle for NavigationLink.
Here is an example of using InsetGroupedListStyle.
struct ContentView: View {
#State var text: String = ""
var body: some View {
NavigationView {
List {
Section(
header: NavigationLink(destination: Text("Page")) {
HStack {
Text("NextPage")
.font(.body)
.foregroundColor(Color.primary)
Spacer()
Image(systemName: "chevron.forward")
.imageScale(.large)
.font(Font.caption2.bold())
.foregroundColor(Color(UIColor.tertiaryLabel))
}
.padding(.vertical, 12)
.padding(.horizontal)
}
.textCase(nil)
.buttonStyle(CellButtonStyle())
.clipShape(RoundedRectangle(cornerRadius: 10))
.padding(.horizontal, -16)
) {}
TextField("Placeholder", text: $text)
}.listStyle(InsetGroupedListStyle())
.onTapGesture {
// hide keyboard...
UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)
}
}
}
}
struct CellButtonStyle: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
configuration.label
.background(
configuration.isPressed
? Color(UIColor.systemGray5)
: Color(UIColor.secondarySystemGroupedBackground)
)
}
}

Here is a possible direction to solve this - by making all taps handled simultaneously and navigate programmatically. Tested with Xcode 12 / iOS 14.
truct ContentView: View {
#State var text: String = ""
var body: some View {
NavigationView {
List {
MyRowView()
TextField("Placeholder", text: $text)
}
.simultaneousGesture(TapGesture().onEnded {
// hide keyboard...
UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)
})
}
}
}
struct MyRowView: View {
#State private var isActive = false
var body: some View {
NavigationLink("NextPage", destination: Text("Page"), isActive: $isActive)
.contentShape(Rectangle())
.onTapGesture {
DispatchQueue.main.async { // maybe even with some delay
self.isActive = true
}
}
}
}
