SwiftUI NavigationView issue. When I slide the navigation panel all the way to the left it disappeared. How can I get the left panel back. Also is there a way to allow the panel to be resize (slide) but no disappear. I am trying to figure out how to allow the panel to be able to slide but not completely disappear
struct ColorDetail: View {
var color: Color
var body: some View {
color
.frame(width: 200, height: 200)
.navigationTitle(color.description.capitalized)
}
}
struct ContentView: View {
var body: some View {
NavigationView {
List {
NavigationLink("Purple", destination: ColorDetail(color: .purple))
NavigationLink("Pink", destination: ColorDetail(color: .pink))
NavigationLink("Orange", destination: ColorDetail(color: .orange))
}
.navigationTitle("Colors")
Text("Select a Color") // A placeholder to show before selection.
}
}
}
As mentioned by workingdog support Ukraine and Asperi, this behavior is indeed a bug, and NavigationView will be deprecated with the release of iOS 16. For your case specifically, it seems like you should consider using NagivationSplitView, in particular, this:
NavigationSplitView {
/* Sidebar */
} detail: {
/* Main content */
}
When implementing this approach, your result will look something like this:
struct ContentView: View {
var body: some View {
NavigationSplitView {
/* Sidebar */
List {
NavigationLink("Purple", destination: ColorDetail(color: .purple))
NavigationLink("Pink", destination: ColorDetail(color: .pink))
NavigationLink("Orange", destination: ColorDetail(color: .orange))
}
.navigationTitle("Colors")
} detail: {
/* Main content */
Text("Select a Color") // A placeholder to show before selection.
}
}
}

I have items on a list. Every item is a NavigationLink that, once clicked, calls this:
import SwiftUI
struct ItemDetail: View {
private var item:MyItem
var body: some View {
ScrollView {
Text (item.fullDescription)
.fixedSize(horizontal: false, vertical: true)
.frame(alignment:.leading)
.padding([.leading, .trailing], 10)
}
}
Descriptions can be long. So, when I scroll the description up to read all content, the content gets over the back button, horribly, like this:
How do I solve that? Is there any way to make the navigation bar opaque?
I am unable to replicate this, but as long as you are using the correct navigation tree it should work as intended. Please see the code below for a simple example.

import SwiftUI
struct ContentView: View {
var body: some View{
NavigationView{
VStack{
NavigationLink(destination: ItemDetail()) {
Text("To new view")
}
}
}
}
}
struct ItemDetail: View {
var body: some View {
ScrollView {
Text ("slkdjf dksljf klsdj fklsdjf klsdj fklsdj fklsdjfklsd jfklsdj fklsdjfklsdjfkldjfkldjfkldjfkldjfkldjfkld jfkldjfkdljfkdlfjkdlfjkdfjdkfj kdjfkdjfkdjfkdjfkdjfdkjfkdfjdkfjdfjdkfj")
.fixedSize(horizontal: false, vertical: true)
.frame(alignment:.leading)
.padding([.leading, .trailing], 10)
}

I'm having an issues with a List inside a NavigationView since iOS 14 update.
Here is a simple breakdown of the code - I've striped everything that doesn't show the issue
struct ContentView: View {
var views = ["Line 1", "Line 2", "Line 3"]
var body: some View {
NavigationView {
VStack {
List {
ForEach(views, id: \.self) { view in
VStack {
Text("\(view)")
}
.background(Color.red)
}
}
}
}
}
}
This produces the following result:
I cant work out why the list is hovering in the center of the navigation view like that. As far as I can tell this should produce a listview that takes up all avaliable space (with the exception of the top where navigationbar would be).
Indeed when run on iOS 13.5 that is the result I get as pictured below:
I've had a read through the documentation but cant work out why this behaviour is suddenly happening.
Any help would be greatly appreciated.
Thanks

It looks like the default styles of a List or NavigationView in iOS 14 may in some cases be different than in iOS 13.
Solution #1 - explicit listStyle
It's no longer always the PlainListStyle (as in iOS 13) but sometimes the InsetGroupedListStyle as well.
You need to explicitly specify the listStyle to PlainListStyle:
.listStyle(PlainListStyle())
Example:
struct ContentView: View {
var views = ["Line 1", "Line 2", "Line 3"]
var body: some View {
NavigationView {
VStack {
List {
ForEach(views, id: \.self) { view in
VStack {
Text("\(view)")
}
.background(Color.red)
}
}
.listStyle(PlainListStyle()) // <- add here
}
}
}
}
Solution #2 - explicit navigationViewStyle
It looks like the NavigationView's default style can sometimes be the DoubleColumnNavigationViewStyle (even on iPhones).
You can try setting the navigationViewStyle to the StackNavigationViewStyle (as in iOS 13):
.navigationViewStyle(StackNavigationViewStyle())
Example:
struct ContentView: View {
var views = ["Line 1", "Line 2", "Line 3"]
var body: some View {
NavigationView {
VStack {
List {
ForEach(views, id: \.self) { view in
VStack {
Text("\(view)")
}
.background(Color.red)
}
}
}
}
.navigationViewStyle(StackNavigationViewStyle()) // <- add here
}
}
I have a NavigationView that contains a ScrollView with a large title. When I navigate to a page with an inline title, then navigate back, the title stays inline rather than reverting to the large title.
This only occurs in iOS 15 - in iOS 14 the title reverts back to the large title as desired. Is there a way to achieve the desired behavior in iOS 15?
Here's an example that illustrates the behavior:
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView {
ScrollView {
NavigationLink("Link", destination: DestinationView())
.padding()
}
.navigationBarTitle("Home", displayMode: .large)
}
}
}
struct DestinationView: View {
var body: some View {
Text("Destination")
.navigationBarTitle("test", displayMode: .inline)
}
}
I have a parent view, in which I don't want any navigation bar, and a child view, where I want an inline navigation bar.
If I navigate to the child view, then back again. The top of the list will have a weird jump effect when scrolling upwards.
I'm sure this is a bug, but does anyone have a workaround? If it helps, I can get access to the underlying UIScrollView/UINavigationController components - but I'm not sure if any of the properties would help.
struct ContentView: View {
var body: some View {
NavigationView {
List( 0...50, id: \.self ) { i in
NavigationLink(destination: HelloView()) {
Text("\(i)")
}
}
.navigationBarHidden( true )
}
}
}
struct HelloView: View {
var body: some View {
Text("Hello")
.navigationBarTitle("Hello", displayMode: .inline)
}
}
I realize this is odd, but this can be alleviated by setting the navigationBarTitle property. In your desired case I would recommend the following:
struct ContentView: View {
var body: some View {
NavigationView {
List( 0...50, id: \.self ) { i in
NavigationLink(destination: HelloView()) {
Text("\(i)")
}
}
.navigationBarTitle("", displayMode: .inline) /// <<--- Insert this line
.navigationBarHidden( true )
}
}
}
By setting the title attribute to blank and using the inline display mode, it rids the view of the large title and actually hides the view correctly.
