Change navigation title text color SwiftUI - swiftui

I have looked and tried every different combo and I can't figure out how to change the color of the text for my view's navigation bar title. Here is my code, also I'm trying to use a custom color that I have already added and used from my assets folder. I know this question has been asked multiple times but literally everything I try doesn't work. I'm on Xcode 11.6 beta1 btw.
import SwiftUI
import Firebase
struct MyProfileView: View {
let navBarAppearance = UINavigationBar.appearance()
var body: some View {
NavigationView {
// Design the View Here
VStack {
//Profile Picture + Info
VStack(alignment: .leading) {
//Profile Picture + Info
HStack(alignment: .bottom, spacing: 15) {
// Profile Picture
Image("PROFILEPICTURE")
.clipShape(Rectangle())
.cornerRadius(100)
.frame(width: 90, height: 90)
.shadow(color: Color.black.opacity(0.3), radius: 1, x: 1, y: 1)
//Username + Zone
VStack(alignment: .leading, spacing: 3) {
Text("Gardn.")
.font(.system(size: 20, weight: .semibold))
.foregroundColor(Color("ShipsOfficer"))
Text("Zone 9, Gold Base")
.font(.system(size: 14, weight: .light))
.foregroundColor(Color("ShipsOfficer").opacity(0.4))
}
Spacer()
}
}
.padding(.leading,30)
// Deco line under info
Rectangle()
.frame(width: 30, height: 2)
.foregroundColor(Color("ShipsOfficer").opacity(0.1)).cornerRadius(100)
.padding(.top,10)
Spacer()
}
.navigationBarHidden(false)
.navigationBarTitle(Text("My Profile"))
.navigationBarItems(trailing:
// Navigation Button
NavigationLink(destination: SettingsView()) {
Image(systemName: "slider.horizontal.3")
.frame(width: 25, height: 25)
.padding()
.font(.title)
.foregroundColor(Color("Freshness"))
}
)
}
}
func customNavBarTitle() {
navBarAppearance.largeTitleTextAttributes = [
.foregroundColor : UIColor.Color("ShipsOfficer),
]
}
}

You can do it with init()
init() {
//Use this if NavigationBarTitle is with Large Font
UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor.red]
//Use this if NavigationBarTitle is with displayMode = .inline
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor.red]
}
Full Code
struct YourView: View {
init() {
//Use this if NavigationBarTitle is with Large Font
UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor.red]
//Use this if NavigationBarTitle is with displayMode = .inline
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor.red]
}
var body: some View {
NavigationView {
List{
Text("1")
}
}
.navigationBarTitle("TEST")
}
}
}

This is tested in Xcode Version 12.3 (12C33), where "Strawberry" is a cutom color in the assets folder :
struct ContentView: View {
init() {
UINavigationBar.appearance().largeTitleTextAttributes = [.foregroundColor: UIColor(named: "Strawberry") ?? .black]
UINavigationBar.appearance().titleTextAttributes = [.foregroundColor: UIColor(named: "Strawberry") ?? .black]
}
var body: some View {
NavigationView {
List {
Text("Apples")
Text("Berries")
Text("Cookies")
Text("Donuts")
}
.navigationBarTitle("My Title")
}
}
}

Function holds System Image rather than image

#ViewBuilder
func TabButton (image: String)-> some View{
Button {
withAnimation{currentTab = image}
} label: {
Image(image)
.resizable()
.renderingMode(.original)
.aspectRatio(contentMode: .fit)
.frame(width: 23, height: 22)
.foregroundColor(currentTab == image ? .primary : .gray)
.frame(maxWidth: .infinity)
}.buttonStyle(GradientButtonStyle())
}
}
I want rather than image from assets as input, system image whom is variable is input here and can change each time and not fixed. thank you
I use it like this,
struct MainView: View {
#State var showMenu: Bool = false
// Hiding Native One.
init(){
UITabBar.appearance().isHidden = true
}
#State var currentTab = "Home"
//offset for both drag gesture and showing menu.
#State var offset: CGFloat = 0
#State var lastStoredOffset: CGFloat = 0
var body: some View {
//let sideBarWidth = getRect().width - 90
// whole navigation view....
NavigationView{
HStack(spacing : 0){
//Side Menu
//SideMenu(showMenu: $showMenu)
//Main Tab View
VStack(spacing: 0){
TabView(selection: $currentTab){
Home(showMenu: $showMenu)
.navigationBarTitleDisplayMode(.inline)
.navigationBarHidden(true)
.tag("Home")
}
this is the tabview code up
VStack(spacing: 0)
{
Divider()
HStack(spacing:0){
// tab buttons
TabButton(image: "Home")
}
}
}
}
I want system image rather than image here , need help please!
I can only guess ... but I think you want something like this?
struct MainView: View {
// Hiding Native One.
init(){
UITabBar.appearance().isHidden = true
}
#State var currentTab = "house"
var body: some View {
//let sideBarWidth = getRect().width - 90
// whole navigation view....
NavigationView{
VStack(spacing : 0) {
//Side Menu
//SideMenu(showMenu: $showMenu)
//Main Tab View
TabView(selection: $currentTab) {
Text("Home Content") // Home(showMenu: $showMenu)
.tag("house")
Text("Star Content") // ...
.tag("star")
Text("Settings Content") // ...
.tag("gear")
}
.tabViewStyle(.page(indexDisplayMode: .never))
Divider()
Spacer(minLength: 10)
HStack {
// tab buttons
TabButton(image: "house")
TabButton(image: "star")
TabButton(image: "gear")
}
}
}
}
func TabButton (image: String)-> some View{
Button {
withAnimation{ currentTab = image }
} label: {
Image(systemName: image)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 23, height: 22)
.foregroundColor( currentTab == image ? .primary : .gray)
.frame(maxWidth: .infinity)
}
// .buttonStyle(GradientButtonStyle())
}
}

SwiftUI: Custom label in navigation link is greyed out

I'm trying to use my custom card view as label to navigation link. this navigation link is also a Grid item.
The result is a
My Card Code:
struct CityCard: View {
var cityData: CityData
var body: some View {
VStack {
Text("\(cityData.name)")
.padding([.top], 10)
Spacer()
Image(systemName: cityData.forecastIcon)
.resizable()
.frame(width: 45, height: 45)
Spacer()
HStack(alignment: .bottom) {
Text(String(format: "%.2f $", cityData.rate))
.padding([.leading, .bottom], 10)
Spacer()
Text(String(format: "%.2f °", cityData.degrees))
.padding([.trailing, .bottom], 10)
}
}.frame(width: 150, height: 150)
.background(Color.blue)
.cornerRadius(10)
.navigationTitle(cityData.name)
}
}
My List View:
struct CityList: View {
var cities: [CityData]
let columns = [
GridItem(.flexible(minimum: 150, maximum: 150)),
GridItem(.flexible(minimum: 150, maximum: 150))
]
var body: some View {
ScrollView {
LazyVGrid(columns: columns, spacing: 20) {
ForEach(self.cities) { item in
NavigationLink(destination: Text(item.name), label: {
CityCard(cityData: item)
})
}
}
}
}
}
someone has a solution why it gives me this opacity?
Update:
The main contact view is:
It's greyed out because you don't yet have a NavigationView in your view hierarchy, which makes it possible to actually navigate to a new view.
You can, for example, wrap your ScrollView in a NavigationView:
var body: some View {
NavigationView {
ScrollView {
LazyVGrid(columns: columns, spacing: 20) {
ForEach(self.cities) { item in
NavigationLink(destination: Text(item.name), label: {
CityCard(cityData: item)
})
}
}
}
}
}
Or, if it's only happening in your preview, add a NavigationView to your preview code:
NavigationView {
CityList(...)
}
Keep in mind that if you have the default accent color (blue, in light mode) that your links will become invisible (since they will be blue) on top of the blue background. You can set a custom accent color in your project or via the accentColor modifier:
NavigationView {
//content
}.accentColor(.black)

Can't sheet with button in ListView SwiftUI

I have a list. In the List there are 2 buttons.
I want to click on each button to present another view with Sheet.
When I first click it it works, but the second time or another tap button it doesn't present the view. Hope you can help me.
My code
My design
Read up on how to use Buttons and sheets. Typically Buttons triggering a sheet is used like this:
EDIT: with suggestion from Philip Dukhov, replace:
Button("Learning") {
}.sheet(isPresented: $isLearning, content: {
LearningView()
})
.onTapGesture {
self.isLearning = true
}
with:
Button(action: {isLearning = true}) {
Text("Learning")
}
.sheet(isPresented: $isLearning) {
LearningView()
}
and do the same for "Test" button, with "isTest" instead of "isLearning" and "TestViewCategory()" instead of "LearningView()".
EDIT 2:
Update "TestView" with:
struct TestView: View {
var title = ""
let models = modelItems
var body: some View {
ScrollView {
VStack {
ForEach(models) { model in
TopicList(model: model)
}
}
}
.navigationBarTitle(title, displayMode: .inline)
.onAppear {
UITableView.appearance().separatorStyle = .none
}
.animation(.spring())
}
}
EDIT 3: here is the test code that works for me:
import SwiftUI
#main
struct TestApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
var body: some View {
NavigationView {
TestView()
}
}
}
struct ButtonView: View {
#State var isLearning: Bool = false
#State var isTest: Bool = false
var body: some View {
HStack {
Button(action: {isLearning = true}) {
Text("Learning")
}
.sheet(isPresented: $isLearning) {
Text("LearningView")
}
.font(.system(size: 16))
.frame(width: 132 , height: 48)
.background(Color(.white))
.overlay(
RoundedRectangle(cornerRadius: 30)
.stroke(Color(#colorLiteral(red: 0.9259920716, green: 0.9261471629, blue: 0.9259716272, alpha: 1)), lineWidth: 1)
)
Button(action: {isTest = true}) {
Text("Test")
}
.sheet(isPresented: $isTest) {
Text("TestViewCategory")
}
.font(.system(size: 16))
.frame(width: 132 , height: 48)
.background(Color(.white))
.overlay(
RoundedRectangle(cornerRadius: 30)
.stroke(Color(#colorLiteral(red: 0.9259920716, green: 0.9261471629, blue: 0.9259716272, alpha: 1)), lineWidth: 1)
)
}
}
}
struct TopicList: View {
// for testing
let model: String
#State private var showSubItem = false
var body: some View {
VStack {
HStack {
Image(systemName: showSubItem ? "arrow.up.circle" : "arrow.down.circle")
.resizable()
.frame(width: 26, height: 26)
.onTapGesture {
withAnimation {
showSubItem.toggle()
}
}
VStack {
VStack(alignment: .leading) {
Text("title")
.font(.custom("Poppins-Regular", size: 24))
.padding(.top,9)
.padding(.bottom,4)
HStack {
Text("Open date")
.font(.custom("Poppins-Regular", size: 12))
Text("Open date")
.font(.custom("Poppins-Regular", size: 12))
Text("Due date")
.font(.custom("Poppins-Regular", size: 12))
Text("Due date")
.font(.custom("Poppins-Regular", size: 12))
}
}
.padding(.leading,17)
.frame(width: 320, height: 70)
.fixedSize(horizontal: false, vertical: true)
if showSubItem {
ButtonView()
.padding(.top,12)
.fixedSize(horizontal: false, vertical: true)
.transition(.opacity)
.transition(.slide)
.padding(.bottom,13)
}
}
.overlay(
RoundedRectangle(cornerRadius: 10)
.stroke(Color(#colorLiteral(red: 0.9259920716, green: 0.9261471629, blue: 0.9259716272, alpha: 1)), lineWidth: 1)
)
}
}
}
}
struct TestView: View {
var title = "nav title"
let models = ["1","2","3"]
var body: some View {
ScrollView {
VStack {
ForEach(models, id: \.self) { model in
TopicList(model: model)
}
}
}
.navigationBarTitle(title, displayMode: .inline)
.onAppear {
UITableView.appearance().separatorStyle = .none
}
.animation(.spring())
}
}

Why the text appear at loading with animation?

I want to hide some text behind the NavigationBarTitle and show it when user press a button, it's working fine. The only problem is with the animation. At loading we see the text moving behind the NavigationBarTitle and that's not what i want.
How can i fix this?
I tried with offset and position but it's not working...
Code :
import SwiftUI
struct TestZStackNavigationView: View {
#State var isShowed = false
let screenSize: CGRect = UIScreen.main.bounds
var body: some View {
NavigationView {
VStack(alignment: .center, spacing: 0){
Text("Im the hidden text")
.fontWeight(.bold)
.foregroundColor(Color.white)
.frame(width: screenSize.width, height: 40, alignment: .center)
.background(Color.red)
// .offset(y: self.isShowed ? -315 : -355)
.position(x: screenSize.width / 2, y: self.isShowed ? 20 : -40)
.animation(.easeIn(duration: 0.5))
Button(action: {
self.isShowed.toggle()
}) {
Text("click me")
}
.navigationBarTitle(Text("Navigation Bar Title"), displayMode:.inline)
}
}
}
}
struct TestZStackNavigationView_Previews: PreviewProvider {
static var previews: some View {
TestZStackNavigationView()
}
}
There are two possibilities
make animation per-state (and no other changes)
.animation(.easeIn(duration: 0.5), value: isShowed)
replace implicit animation as modifier and add explicit animation in action
.position(x: screenSize.width / 2, y: self.isShowed ? 20 : -40)
// .animation(.easeIn(duration: 0.5)) // remove from here
Button(action: {
withAnimation(Animation.easeIn(duration: 0.5)) { // << add this
self.isShowed.toggle()
}
}) {
Text("click me")
}
I want to use it now with an ObservedObject but i got that same behavior as first code. Why?
struct TestZStackNavigationView: View {
// #State var isShowed = false
let screenSize: CGRect = UIScreen.main.bounds
#ObservedObject var online = NetStatus()
var body: some View {
NavigationView {
VStack(alignment: .center, spacing: 0){
Text("Im the hidden text")
.fontWeight(.bold)
.foregroundColor(Color.white)
.frame(width: screenSize.width, height: 40, alignment: .center)
.background(Color.red)
.position(x: screenSize.width / 2, y: online.connected ? -40 : 20)
.animation(.easeIn(duration: 0.5), value: online.connected)
.navigationBarTitle(Text("Navigation Bar Title"), displayMode:.inline)
}
}
}
}

How to create Radiobuttons in SwiftUI?

I would like to react on a choice of a user. Something similar to this example:
In a 2nd stage would I like to show additional content below each radiobutton, e.g. moving the buttons 2 and 3 from each other in order to give a list of websites for allowing.
So far I haven't found how to do this in SwiftUI.
Many thanks in advance!
Picker(selection: $order.avocadoStyle, label: Text("Avocado:")) {
Text("Sliced").tag(AvocadoStyle.sliced)
Text("Mashed").tag(AvocadoStyle.mashed)
}.pickerStyle(RadioGroupPickerStyle())
This is the code from the 2019 swiftUI essentials keynote (SwiftUI Essentials - WWDC 2019. Around 43 minutes in the video they show this example.
It will look like this:
check this out...an easy to use SwiftUI RadiobuttonGroup for iOS
you can use it like this:
RadioButtonGroup(items: ["Rome", "London", "Paris", "Berlin", "New York"], selectedId: "London") { selected in
print("Selected is: \(selected)")
}
and here is the code:
struct ColorInvert: ViewModifier {
#Environment(\.colorScheme) var colorScheme
func body(content: Content) -> some View {
Group {
if colorScheme == .dark {
content.colorInvert()
} else {
content
}
}
}
}
struct RadioButton: View {
#Environment(\.colorScheme) var colorScheme
let id: String
let callback: (String)->()
let selectedID : String
let size: CGFloat
let color: Color
let textSize: CGFloat
init(
_ id: String,
callback: #escaping (String)->(),
selectedID: String,
size: CGFloat = 20,
color: Color = Color.primary,
textSize: CGFloat = 14
) {
self.id = id
self.size = size
self.color = color
self.textSize = textSize
self.selectedID = selectedID
self.callback = callback
}
var body: some View {
Button(action:{
self.callback(self.id)
}) {
HStack(alignment: .center, spacing: 10) {
Image(systemName: self.selectedID == self.id ? "largecircle.fill.circle" : "circle")
.renderingMode(.original)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: self.size, height: self.size)
.modifier(ColorInvert())
Text(id)
.font(Font.system(size: textSize))
Spacer()
}.foregroundColor(self.color)
}
.foregroundColor(self.color)
}
}
struct RadioButtonGroup: View {
let items : [String]
#State var selectedId: String = ""
let callback: (String) -> ()
var body: some View {
VStack {
ForEach(0..<items.count) { index in
RadioButton(self.items[index], callback: self.radioGroupCallback, selectedID: self.selectedId)
}
}
}
func radioGroupCallback(id: String) {
selectedId = id
callback(id)
}
}
struct ContentView: View {
var body: some View {
HStack {
Text("Example")
.font(Font.headline)
.padding()
RadioButtonGroup(items: ["Rome", "London", "Paris", "Berlin", "New York"], selectedId: "London") { selected in
print("Selected is: \(selected)")
}
}.padding()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {

}
}
struct ContentViewDark_Previews: PreviewProvider {

I just edited #LizJ answer , by adding Binding instead of didTapActive & didTapInactive , so like that it will looks like other SwiftUI elements
import SwiftUI
struct RadioButton: View {
#Binding var checked: Bool //the variable that determines if its checked
var body: some View {
Group{
if checked {
ZStack{
Circle()
.fill(Color.blue)
.frame(width: 20, height: 20)
Circle()
.fill(Color.white)
.frame(width: 8, height: 8)
}.onTapGesture {self.checked = false}
} else {
Circle()
.fill(Color.white)
.frame(width: 20, height: 20)
.overlay(Circle().stroke(Color.gray, lineWidth: 1))
.onTapGesture {self.checked = true}
}
}
}
}
I'm using swift4, Catalina OS and Xcode 11.2 and was having the issue where RadioGroupPickerStyle was unavailable for iOS and .radiogroup just didn't work (it froze in build) so I made my own that's reusable for other occasions. (notice its only the button so you have to handle the logic yourself.) Hope it helps!
import SwiftUI
struct RadioButton: View {
let ifVariable: Bool //the variable that determines if its checked
let onTapToActive: ()-> Void//action when taped to activate
let onTapToInactive: ()-> Void //action when taped to inactivate
var body: some View {
Group{
if ifVariable {
ZStack{
Circle()
.fill(Color.blue)
.frame(width: 20, height: 20)
Circle()
.fill(Color.white)
.frame(width: 8, height: 8)
}.onTapGesture {self.onTapToInactive()}
} else {
Circle()
.fill(Color.white)
.frame(width: 20, height: 20)
.overlay(Circle().stroke(Color.gray, lineWidth: 1))
.onTapGesture {self.onTapToActive()}
}
}
}
}
TO USE: Put this in any file and you can use it as you would any other view anywhere else in the project. (we keep a global folder that has a buttons file in it)
I will use the previous answer of #LizJ and i will add a text after the radio button to resemble (RadioListTile in Flutter)
struct RadioButton: View {
let ifVariable: Bool //the variable that determines if its checked
let radioTitle: String
var onTapToActive: ()-> Void//action when taped to activate
let onTapToInactive: ()-> Void //action when taped to inactivate
var body: some View {
Group{
if ifVariable {
HStack(alignment: .center, spacing: 16) {
ZStack{
Circle()
.fill(AppColors.primaryColor)
.frame(width: 20, height: 20)
Circle()
.fill(Color.white)
.frame(width: 8, height: 8)
}.onTapGesture {self.onTapToInactive()}
Text(radioTitle)
.font(.headline)
}
} else {
HStack(alignment: .center, spacing: 16){
Circle()
.fill(Color.white)
.frame(width: 20, height: 20)
.overlay(Circle().stroke(Color.gray, lineWidth: 1))
.onTapGesture {self.onTapToActive()}
Text(radioTitle)
.font(.headline)
}
}
}
}
I will also provide an example for the selection logic
we will create a enum for radio cases
enum PaymentMethod: Int {
case undefined = 0
case credit = 1
case cash = 2
}
then we will create #State variable to carry the selection, i will not recreate another SwiftUI view but only explain the basic concept without any boilerplate code
struct YourView: View {
#State private var paymentMethod: PaymentMethod
var body: some View {
RadioButton(ifVariable: paymentMethod == PaymentMethod.credit,radioTitle: "Pay in Credit", onTapToActive: {
paymentMethod = .credit
}, onTapToInactive: {})
RadioButton(ifVariable: paymentMethod == PaymentMethod.cash,radioTitle: "Pay in Cash", onTapToActive: {
paymentMethod = .cash
}, onTapToInactive: {})
}
}
with this previous code you can toggle between radio buttons in SwiftUI with a text after each selection to resemble (RadioListTile in Flutter)
