Navigation stuff in SwiftUI - ios

Question

I'm trying to figure out how to use the navigation bar in SwiftUI
I want to put BarButtonItem and images inside the NavigationBar
I have been able to display the navigation bar and put titles
var body: some View {
NavigationView{
List(0...5) { note in
VStack(alignment: .leading) {
Text("title")
Text("Date")
.font(.subheadline)
.foregroundColor(.secondary)
}
}
.navigationBarTitle(Text("Notes"))
}
}

Answer 1

iOS 14
You should use the toolbar modifier:
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button("Cancel") { /* action */ }
}
ToolbarItem(placement: .navigationBarTrailing) {
Button(action: { /* Actions */ }, label: {
HStack {
Image(systemName: "trash")
Text("Delete")
}
})
.foregroundColor(.red) // You can apply colors and other modifiers too
}
}
Note 1: You can have ANY View there. (not only a Button) and also any modifiers
Note 2: Both codes above and below will generate the same look items but with different approachs
iOS 13 and above (deprecated but still works)
You should use .navigationBarItems() modifier. For example you can add Button or Image like this:
.navigationBarItems(
leading: Button("Cancel") {
// Actions
},
trailing: Button(action: {
// Actions
}, label: { Label("Delete", systemImage: "trash") }
).foregroundColor(.red) // You can apply colors and other modifiers too
)
💡 Pro TIP
Always try to encapsulate each item in a separated struct, so your code will be simplified and very easy to replace with newer technologies. for example, take a look at this sample:
.navigationBarItems(
leading: MyCustomButtonItem(),
trailing: MyCustomButtonItem(text: "foo", image: "Bard")
)

Answer 2

.navigationBarItems() is the function you are looking for. You can specify a leading view, trailing view, or both. Within the view, you can specify horizontal and vertical stacks to add additional buttons.
var body: some View {
NavigationView{
List(0...5) { note in
VStack(alignment: .leading) {
Text("title")
Text("Date")
.font(.subheadline)
.foregroundColor(.secondary)
}
}
.navigationBarItems(leading: HStack {
Button(action: {}, label: {Image(systemName: "star.fill")})
Button(action: {}, label: {Text("Edit")})
}, trailing: VStack {
Button(action: {}, label: {Image(systemName: "star.fill")})
Button(action: {}, label: {Text("Edit")})
})
.navigationBarTitle(Text("Notes"))
}
}

SwiftUI 2
In SwiftUI 2 / iOS 14 the navigationBarItems modifier is deprecated.
Instead we should use a toolbar with ToolbarItems.
NavigationView {
List {
// ...
}
.navigationTitle("Notes")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button("Tap me") {
// action
}
}
ToolbarItem(placement: .navigationBarTrailing) {
Image(systemName: "plus")
}
}
}
You can see the documentation for more ToolbarItemPlacements.

Check the image here
The toolbar() modifier lets us add single or multiple bar button items to the leading and trailing edge of a navigation view, as well as other parts of our view if needed. These might be tappable buttons, but there are no restrictions – you can add any sort of view.
var body: some View {
NavigationView {
ScrollView {
VStack{
}//: VStack
}//: Scroll
.navigationTitle("Settings")
.toolbar(content: {
ToolbarItemGroup(placement: .navigationBarTrailing) {
Button {
presentationMode.wrappedValue.dismiss()
} label: {
Image(systemName: "xmark")
}
}
})
.padding()
}//: Navigation
}

put this from parentViewController
NavigationLink(destination: NotesListView())
