How do I make a BottomSheetScaffold completely transparent?
I have a random white background showing up, even when I set the sheetBackgroundColor = Color.Transparent.
Here's my BottomSheetScaffold
BottomSheetScaffold(
modifier = Modifier.background(Color.Red),
scaffoldState = bottomSheetScaffoldState,
sheetContent = {
Column(Modifier.fillMaxWidth(),
horizontalAlignment = Alignment.CenterHorizontally) {
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
Text("Hello")
}
},
sheetPeekHeight = 10.dp,
sheetBackgroundColor = Color.Transparent,
)
Any ideas on how to remove this white box inside the bottom sheet?
Thanks!

I'm looking how to align text to the top of screen, do you know how to?
import SwiftUI
struct RegisterSignInScreen: View {
var body: some View {
VStack {
Text("Welcome Back!")
.font(.title)
.fontWeight(.bold)
.multilineTextAlignment(.center)
.padding(.bottom, 5.0)
Text("Please sign in to your account")
.font(.subheadline)
.fontWeight(.bold)
.foregroundColor(Color.gray)
.multilineTextAlignment(.center)
}
}
}
struct RegisterSignInScreen_Previews: PreviewProvider {
static var previews: some View {
RegisterSignInScreen()
}
}

I tried to embed my VStack in a ZStack:
ZStack(alignment: .top)
But it didn't work.
To see why this is happening you can add a background to your VStack or ZStack
ZStack {
VStack {
//Text items
}
}
.background(.red)
What you will notice (maybe unexpectedly) is that the stack is only as big as it needs to be to contain the text items.
When you add alignment to the stack it aligns the content within the stack to the specified edge of the relatively small stack. It doesn't align the stack to an edge of the screen, or change the size of the stack. What you're actually looking to do is align the stack, not it's content.
In order to align to the top of the screen you can make the stack fill the entire height of the screen. Either by adding a Spacer() at the bottom of the VStack that will fill the remaining vertical space pushing the content upwards, or by applying a frame with .infinity maxHeight: and top aligned content to the VStack.
VStack {
Text("Hello World!")
Spacer()
}
VStack {
Text("Hello World!")
}
.frame(maxHeight: .infinity, alignment: .top)
Alternatively if required for your view, you can do a similar thing with a second stack containing your text stack like so:
var body: some View {
VStack {
welcomeText
Spacer()
}
}
var welcomeText: some View {
VStack {
Text("Welcome Back!")
.font(.title)
.fontWeight(.bold)
.multilineTextAlignment(.center)
.padding(.bottom, 5.0)
Text("Please sign in to your account")
.font(.subheadline)
.fontWeight(.bold)
.foregroundColor(Color.gray)
.multilineTextAlignment(.center)
}
}
You can do this in a couple of ways, but the most obvious way is to simply add a Spacer() in the bottom of the VStack
Like so:
struct RegisterSignInScreen: View {
var body: some View {
VStack {
Text("Welcome Back!")
Text("Please sign in to your account")
Spacer() // <- HERE
}
}
}
This will push your content in the VStack to the top.
Alternatively, you can add a frame modifier and force your VStack height and add the alignment there using .frame
struct RegisterSignInScreen: View {
var body: some View {
VStack {
Text("Welcome Back!")
Text("Please sign in to your account")
}
.frame(maxHeight: .infinity, alignment: .top) // <- HERE
}
}
ZStack(alignment: .top) works, but not the same way as you think)
try to do:
ZStack(alignment: .top){
}
.background(Color.green)
and you will understand why so :)
you need to use spacer :)
VStack {
YourView()
Spacer()
}
I embedded a TabView in a NavigationView and the Text in the view gets pushed down slightly. I've tried moving the views around however it just ends up breaking functionally. You can see the green text is not vertically aligned to the rest of the device, but instead aligned to the content under the navigation bar.
var body: some View {
NavigationView{
TabView {
Text("TEST 1").foregroundColor(color).font(Font.custom("Catamaran-ExtraBold", size: 48)).navigationTitle("TEST 1")
Text("TEST 2").foregroundColor(color).font(Font.custom("Catamaran-ExtraBold", size: 48)).navigationTitle("TEST 2")
}
.foregroundColor(.black).navigationBarTitleDisplayMode(.inline)
.font(Font.custom("Catamaran-ExtraBold", size: 20))
.navigationBarItems(
leading:
NavigationLink(destination: SettingsView(), label: {
Image(systemName: "gearshape")
})).foregroundColor(colorScheme == .dark ? .white : .black)
}
.navigationViewStyle(.stack)
.ignoresSafeArea()
.tabViewStyle(.page)
.indexViewStyle(.page(backgroundDisplayMode: .always))
}
It's a bit strange what you are trying to achieve. Centering it as if the NavigationView wasn't there means that the view is no longer centered in its container. It will look strange and not centered like this.
However, here is how you can achieve this. This example uses GeometryReaders to measure the height of the navigation bar, and take away half that so the text now appears centered to the safe area.
Before:
struct ContentView: View {
var body: some View {
NavigationView {
TabView {
Text("TEST 1")
.font(.title.bold())
.foregroundColor(.green)
.navigationTitle("TEST 1")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.red.opacity(0.1))
Text("TEST 2")
.font(.title.bold())
.foregroundColor(.green)
.navigationTitle("TEST 2")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.red.opacity(0.1))
}
.tabViewStyle(.page)
.indexViewStyle(.page(backgroundDisplayMode: .always))
}
.navigationViewStyle(.stack)
}
}
After:
struct ContentView: View {
var body: some View {
GeometryReader { geoRoot in // <- HERE
NavigationView {
GeometryReader { geo in // <- HERE
let yOffset = (geoRoot.safeAreaInsets.top - geo.safeAreaInsets.top) / 2 // <- HERE
TabView {
Text("TEST 1")
.font(.title.bold())
.foregroundColor(.green)
.navigationTitle("TEST 1")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.red.opacity(0.1))
// <- Also replicate offset here, not done for demo
Text("TEST 2")
.font(.title.bold())
.foregroundColor(.green)
.navigationTitle("TEST 2")
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(Color.red.opacity(0.1))
.offset(y: yOffset) // <- HERE
}
.tabViewStyle(.page)
.indexViewStyle(.page(backgroundDisplayMode: .always))
}
}
.navigationViewStyle(.stack)
}
}
}
Result
Before: TEST 1 tab
After: TEST 2 tab
Here is my View:
struct HomeView: View {
#ObservedObject var instance = Instance()
#State var dotColor = Color.gray
var repeatingAnimation: Animation {
Animation
.easeInOut(duration: 1.0)
.repeatForever()
}
var body: some View {
ZStack {
TabView(selection: $selectedTab) {
Settings(auth: auth)
.tabItem {
Image(systemName: "gear")
Text("Settings")
}.tag(0)
ZStack {
MapView(locationManager: locationManager)
Color.black.opacity(self.instance.status.opacity)
VStack {
Spacer()
Button(action: {
print("clicked")
withAnimation(self.repeatingAnimation) {
self.dotColor = Color.white
}
self.instance.changeStatus()
}){
HStack {
Text(self.instance.status.text)
.font(.system(size: 24))
.fontWeight(.bold)
.foregroundColor(Color.white)
Circle().frame(width: 12, height: 12)
.foregroundColor(self.dotColor)
.colorMultiply(self.dotColor)
.overlay(
Circle()
.stroke(Color.black, lineWidth: 1)
)
}
}.padding()
My animation, changes the color of the Circle() from gray to white every second. However, it also changes my ZStack color opacity (Color.black.opacity(self.instance.status.opacity)) every second - even though it's not related to my animation.
If I remove the animation this weird behaviour does not occur to the ZStack opacity.
How can I fix this?
You can disable animation of some modifier explicitly, like
Color.black.opacity(self.instance.status.opacity)
.animation(nil)
I am trying to change background color main this view but unable to do it. I tried to put background(Color.green) at HStack, VSTack and even on ZStack but it did not work, not sure if i am putting at right place. By default it is taking phone or simulator color which is white but i want to apply custom background color
My Xcode version is 11.5
struct HomePageView: View {
#State var size = UIScreen.main.bounds.width / 1.6
var body: some View {
GeometryReader{_ in
VStack {
HStack {
ZStack{
// main home page components here....
NavigationView{
VStack {
AssignmentDaysView()
}.background(Color.lairBackgroundGray)
.frame(width: 100, height: 100, alignment: .top)
.navigationBarItems(leading: Button(action: {
self.size = 10
}, label: {
Image("menu")
.resizable()
.frame(width: 30, height: 30)
}).foregroundColor(.appHeadingColor), trailing:
Button(action: {
print("profile is pressed")
}) {
HStack {
NavigationLink(destination: ProfileView()) {
LinearGradient.lairHorizontalDark
.frame(width: 30, height: 30)
.mask(
Image(systemName: "person.crop.circle")
.resizable()
.scaledToFit()
)
}
}
}
).navigationBarTitle("Home", displayMode: .inline)
}
HStack{
menu(size: self.$size)
.cornerRadius(20)
.padding(.leading, -self.size)
.offset(x: -self.size)
Spacer()
}
Spacer()
}.animation(.spring()).background(Color.lairBackgroundGray)
Spacer()
}
}
}
}
}
struct HomePageView_Previews: PreviewProvider {
static var previews: some View {
HomePageView()
}
}
In your NavigationView you have a VStack. Instead you can use a ZStack and add a background below your VStack.
Try the following:
NavigationView {
ZStack {
Color.green // <- or any other Color/Gradient/View you want
.edgesIgnoringSafeArea(.all) // <- optionally, if you want to cover the whole screen
VStack {
Text("assignments")
}
.background(Color.gray)
.frame(width: 100, height: 100, alignment: .top)
}
}
Note: you use many stacks wrapped in a GeometryReader which you don't use. Consider simplifying your View by removing unnecessary stacks. Also you may not need a GeometryReader if you use UIScreen.main.bounds (however, GeometryReader is preferred in SwiftUI).
Try removing some layers: you can start with removing the top ones: GeometryReader, VStack, HStack...
Try the following:
Change the view background color especially safe area also
struct SignUpView: View {
var body: some View {
ZStack {
Color.blue //background color
}.edgesIgnoringSafeArea(.all)
In SwiftUI, when a NavigationLink is placed inside of a Form, an arrow automatically appears on the trailing side of the NavigationLink. How can the color of this arrow be changed?
struct example: View {
var body: some View {
NavigationView {
Form {
NavigationLink(destination: Text("Example destination")) {
Text("Example link")
}
}
}
}
}
Form/List is reusing UITableView and it's always been a problem to change the disclosure indicator tintColor *See: Question
So it comes to no surprise that .accentColor won't work here either.
The suggestions have mostly been to replace it with a custom view.
So lets do the same in SwiftUI.
Solution:
struct ContentView: View {
var body: some View {
NavigationView {
Form {
//Overlap NavigationLink and our Custom Cell arrangement
ZStack {
//Create a NavigationLink without the disclosure indicator
NavigationLink(destination: Text("Hello, World!")) {
EmptyView()
}
//Replicate the default cell
HStack {
Text("Custom UI")
Spacer()
Image(systemName: "chevron.right")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 7)
.foregroundColor(.red) //Apply color for arrow only
}
.foregroundColor(.purple) //Optional: Apply color on all inner elements
}
//Default style
NavigationLink(destination: Text("Hello, World!")) {
Text("Default UI")
}
}
}
}
}
NavigationLink with EmptyView gets rid of the default disclosure indicator
HStack is our Custom Cell View that replicates the default cell arrangement
Image(systemName: "chevron.right") is our replacement for the diclosure indicator
.foregroundColor will allow us to splash a color on either the entire HStack or just the Image (your choice)
ZStack allows to overlap the above two.
The NavigationLink basically makes the entire cell tappable
Result:
You can provide a custom view and hide the default NavigationLink arrow:
NavigationLink(destination: Text("Hello, World!")) {}
.opacity(0)
.background(
HStack {
Text("Custom UI")
Spacer()
Image(systemName: "chevron.right")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 7)
.foregroundColor(.red) //Apply color for arrow only
}
.foregroundColor(.purple)
)
Or specify the NavigationLink as background (so you have auto sizing):
HStack {
Text("Custom UI")
Spacer()
Image(systemName: "chevron.right")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 7)
.foregroundColor(.red) //Apply color for arrow only
}
.foregroundColor(.purple)
.background(
NavigationLink(destination: Text("Hello, World!")) {}
.opacity(0)
)
