How to go to another view with button click - swiftui

Question

I have a button in my code and I have a file called LogindView.swift
I cannot get the code to open another view file when clicking on the button.
Can anybody give me an example on how to do it.
In my button action I have tried to write LogindView() but i just gives me a warning.
"Result of 'LogindView' initializer is unused"
Button(action: {
// Do action
LogindView()
}, label: {
//** Label text
Text("Logind")
.font(.headline)
.padding(.all)
.foregroundColor(Color.white)
})
.background(Color.blue)

You essentially have 3 options to transition between views depending on your needs.
First, you can use a NavigationView. This will provide a back button and will allow the user to go back. Note that there are some bugs currently when you don't put the NavigationLink inside of a List as per https://stackoverflow.com/a/57122621/3179416
import SwiftUI
struct MasterView: View {
var body: some View {
NavigationView {
List {
NavigationLink(destination: LoginView()) {
Text("Login")
}
}
.navigationBarTitle(Text("Master"))
}
}
}
struct LoginView: View {
var body: some View {
Text("Login View")
}
}
Second, you can present a modal using .sheet. This will present a modal that appears on top of the current view but it can be dismissed by the user by dragging it down.
import SwiftUI
struct MasterView: View {
#State var isModal: Bool = false
var body: some View {
Button("Login") {
self.isModal = true
}.sheet(isPresented: $isModal, content: {
LoginView()
})
}
}
struct LoginView: View {
var body: some View {
Text("Login View")
}
}
Third, you can just use an if statement to change the current view to your Login View like so
import SwiftUI
struct MasterView: View {
#State var showLoginView: Bool = false
var body: some View {
VStack {
if showLoginView {
LoginView()
} else {
Button("Login") {
self.showLoginView = true
}
}
}
}
}
struct LoginView: View {
var body: some View {
Text("Login View")
}
}
If you would like to animate this, so that the transition doesn't appear so abruptly, you can also do this:
import SwiftUI
struct MasterView: View {
#State var showLoginView: Bool = false
var body: some View {
VStack {
if showLoginView {
LoginView()
.animation(.spring())
.transition(.slide)
} else {
Button("Login") {
withAnimation {
self.showLoginView = true
}
}.animation(.none)
}
}
}
}
struct LoginView: View {
var body: some View {
Text("Login View")
}
}

You can use navigation link instead button
var body: some View {
VStack {
Text("Title")
.font(.headline)
Image("myimage").clipShape(Circle())
Text("mytext").font(.title)
NavigationLink(destination: AnotherView()) {
Image(systemName: "person.circle").imageScale(.large)
}
}
}
