As written in the title i am trying to find a way to change the navigation style from left-to-right to a right-to-left Arabic style.
This is a simple NavigationView code I made:
import SwiftUI
struct HomeView: View {
var body: some View {
NavigationView {
List {
NavigationLink(destination: Text("Destination")) {
Text("Go To Destination")
}
}
.navigationTitle("Text")
}
}
}
struct HomeView_Previews: PreviewProvider {
static var previews: some View {
HomeView()
}
}

I am engaging in a small SwiftUI exercise to learn how to pass data between views using NavigationLink. I set up ContentView to send a message to the SecondView after tapping the ContentView NavigationLink. Tapping NavigationLink in the SecondView then sends the message to the ThirdView. However, I am noticing a strange UI occurrence by the time I get to ThirdView. See the screenshot below:
Any idea why this NavigationView issue is occurring? Is it related to having NavigationView in all 3 views?
Here is my code:
ContentView
struct ContentView: View {
var body: some View {
NavigationView {
NavigationLink(destination: SecondView(message: "Hello from ContentView")) {
Text("Go to Second View")
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
SecondView
struct SecondView: View {
var message: String
var body: some View {
Text("\(message)")
NavigationView {
NavigationLink(destination: ThirdView(message: self.message)) {
Text("Go to Third View")
}
}
}
}
struct SecondView_Previews: PreviewProvider {
static var previews: some View {
SecondView(message: String())
}
}
ThirdView
struct ThirdView: View {
var message: String
var body: some View {
NavigationView {
Text("\(message)")
}
}
}
struct ThirdView_Previews: PreviewProvider {
static var previews: some View {
ThirdView(message: String())
}
}
Feedback is appreciated. Thanks!
remove the second navigation view
struct SecondView: View {
var message: String
var body: some View {
VStack(spacing: 100 ) {
Text("\(message)")
NavigationLink(destination: ThirdView(message: self.message)) {
Text("Go to Third View")
}
}
}
}
struct ThirdView: View {
var message: String
var body: some View {
Text("\(message)")
}
}
In SwiftUI I want to implement the following view. But I have no idea how I can put the navigation bar in the white view inside. Because it is placed on top of the purple view by default.
import SwiftUI
struct ContentView: View {
var body: some View {
ZStack {
Color.purple
WhiteView() // the white view
.padding(.top, 30)
.padding()
}
.edgesIgnoringSafeArea(.all)
}
}
import SwiftUI
struct WhiteView: View {
var body: some View {
Color.white
.cornerRadius (12)
}
}
struct WhiteView_Previews: PreviewProvider {
static var previews: some View {
WhiteView()
}
}
Here is possible approach - use NavigationView over color view, so it takes frame of parent view but not full screen
Tested with Xcode 12.4 / iOS 14.4
struct WhiteView: View {
var body: some View {
Color.white
.overlay(NavigationView {
NavigationLink("Test", destination: Text("Details"))
})
.cornerRadius (12)
}
}
I took your code, stuck it in a NavigationView, added a .navigationTitle, .toolbar and ToolBarItem and this is the View I got:
Code:
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView {
ZStack {
Color.purple
WhiteView() // the white view
.padding(.top, 30)
.padding()
}
.edgesIgnoringSafeArea(.all)
.navigationTitle("Your Friends")
.toolbar {
ToolbarItem {
Text("Right Button")
}
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct WhiteView: View {
var body: some View {
Color.white
.cornerRadius (12)
}
}
What, exactly is your question/problem? Everything is in the white area.
to make it short: I want to have the same view of the list like in the first image i shared. But when I add a navigation bar item the list looks strange to me. It this a bug of the new version of Swift/XCode or needs something to be changed?
Code:
import SwiftUI
import CoreData
struct ContentView: View {
var body: some View {
NavigationView {
List{
Text("test1")
Text("test2")
Text("test3")
}
.navigationTitle("Test")
// .navigationBarItems(leading:
// Text("Test")
// )
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
Try using .navigationViewStyle as below:
struct ContentView: View {
#State private var isFullScreen = false
var body: some View {
NavigationView {
List{
Text("One")
Text("Two")
}
.navigationTitle("Testt")
.navigationBarItems(leading: Text("Add"))
}
.navigationViewStyle(StackNavigationViewStyle())
}
}
Hey! Give This A Try!
var body: some View {
NavigationView {
List{
Text("One")
Text("Two")
}
.navigationTitle("Testt, displayMode: .inline)
.navigationBarItems(leading: Text("Add"))
}
}
}
I started to use SwiftUI after a couple years of UIKit.. This is not a piece of cake lol.
Alright, so I am trying to build an app that has a tab bar with 2 elements. Each Tab with contain a ViewController (View now) and they will be embedded in a NavigationController (NavigationView now)
The actual result is this
and I am expecting to have a nav bar with a title set to Home.
Could you explain me what I do wrong here? i followed the documentation and a couple tutorials, and I don't seem to do differently.
import SwiftUI
struct TabBarView: View {
var body: some View {
TabView() {
RedView()
.tabItem({
Image(systemName: "house.fill")
Text("Home")
})
.tag(0)
BlueView()
.tabItem({
Image(systemName: "dollarsign.square.fill")
Text("Trade")
})
.tag(1)
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
TabBarView()
}
}
struct RedView: View {
var body: some View {
NavigationView {
List {
Text("test")
}
}
.navigationBarTitle("Home")
}
}
struct BlueView: View {
var body: some View {
NavigationView {
List {
Text("test2")
}
}
.navigationBarTitle("Trade")
}
}
This is the file that contains everything at the moment. Thanks in advance for any future help!
The .navigationBarTitle should be inside NavigationView
struct RedView: View {
var body: some View {
NavigationView {
List {
Text("test")
}
.navigationBarTitle("Home") // << here !!
}
}
}
I'm following through some swiftUI tutorial and I couldn't figure out what this meant.
This was the very first step, and I haven't done anything other than adding the NavigationView. How do I resolve this?
That's just container, you need some content inside, If you are just trying something out try following:
var body: some View {
NavigationView {
Text("Testing")
}
}
You cannot have an empty NavigationView. Add something inside.
struct ContentView: View {
var body: some View {
NavigationView {
Text("Text here")
}
}
}
FIRST: Add new SwiftUI-View (Name: MapView.swift without code-changing )
SECOND: Add new SwiftUI-View (Name: SecondView.swift)
THEN Change ContentView and SecondView:
a) ContentView.swift
import SwiftUI
struct ContentView: View {
var body: some View {
VStack {
MapView() // on upper Screen will appear: "Hello World"
NavigationView {
NavigationLink(destination: SecondView()) {
VStack {
Text("click here")
.fontWeight(.heavy)
.font(.largeTitle)
.padding()
Text("go to screen II")
}
}
} //End of NavigationView
}// End of VStack
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
VStack {
ContentView()
}
}
}
b) SecondView.swift
import SwiftUI
struct SecondView: View {
var body: some View {
VStack {
Text("Screen II")
.fontWeight(.heavy)
.foregroundColor(.blue)
.font(.largeTitle)
.padding()
Text("you changed it")
Text("GRATULATION!")
}
}
}
struct SecondView_Previews: PreviewProvider {
static var previews: some View {
SecondView()
}
}
c) MapView.swift
import SwiftUI
struct MapView: View {
var body: some View {
Text(/*#START_MENU_TOKEN#*/"Hello, World!"/*#END_MENU_TOKEN#*/)
}
}
struct MapView_Previews: PreviewProvider {
static var previews: some View {
MapView()
}
}
