Go to a specific View with Button

You don't show a lot of code, so hard to say.

But you should call ExhibitView() when showExhibitView is true.

Here is a simplified example of such code.

struct ExhibitView: View {
    
    var body: some View {
        Text("I show exhibit")
    }
}

struct ContentView: View {
    @State var showExhibitView = false
    
    var body: some View {

        Button("Save"){
            print("Save")
            Timer.scheduledTimer(withTimeInterval: 3.0, repeats: false) { _ in.  // 3 s to have time to notice
                    showExhibitView = true
                }
            }

        if showExhibitView {
            ExhibitView()
        }
    }
    
}

If you replace

            showExhibitView = true

with

            showExhibitView.toggle()

You see ExhibitView appear and disappear.

If you want something that behaves more like a NavigationLink, do it with Bindings:

struct FirstView: View {
    @Binding var showExhibitView : Bool
    
    var body: some View {
        Button("Save"){
            print("Save")
            Timer.scheduledTimer(withTimeInterval: 3.0, repeats: false) { _ in
                showExhibitView = true
                }
            }
    }
}

struct ExhibitView: View {
    @Binding var showExhibitView : Bool

    var body: some View {
        
        Button("Return"){
                showExhibitView = false
            }
        Text("I show exhibit")
    }
}

struct ContentView: View {
    @State var showExhibitView = false
    
    var body: some View {

        if showExhibitView {
            ExhibitView(showExhibitView: $showExhibitView)
        } else {
            FirstView(showExhibitView: $showExhibitView)
        }
    }
    
}

Hey thanks for answering @Claude31 but that does not fit with I what I want. There is the all code of the page and a brief resumé of the idea. It's and AddView called AddExhibView to implement new element in a Database, so I want after pressing the save button to show the ListView called ExhibitView where I display all the data. There is the code :

import SwiftUI
import CoreData

struct AddExhibView: View {
    @Environment(\.dismiss) var dismiss
    @Environment(\.managedObjectContext) private var viewContext
    
    @State private var name: String = ""
    @State private var info: String = ""
    @State private var isOnline: Bool = false
    @State private var startDate: Date = Date()
    @State private var endDate: Date = Date()
    @State private var contactBuyer = false
    
    
    @State private var showAlert: Bool = false
    
    @State private var alertMessage: String = "Il en manque ..."
    
    //MARK: Drag&Drop Stuff
    @State var firstImage =  NSImage(named: "image")
    @State var firstUrl: URL?
    

    @State var secondImage =  NSImage(named: "image")
    @State var secondUrl: URL?
    
    @State var thirdImage =  NSImage(named: "image")
    @State var thirdUrl: URL?
    
    //MARK: Aheviement Stuff
    @State private var showAchievement: Bool = false
    let achievement =  Achievement(title: "Succès", description: "L'élément a été ajouté avec succès")
    
    @State private var showExhibitView: Bool = false
    
    
    var body: some View {
        
        HStack{
            DropImage(image: $firstImage, url: $firstUrl)
            
            if firstImage != nil {
                DropImage(image: $secondImage, url: $secondUrl)
                
                if secondImage != nil{
                    DropImage(image: $thirdImage, url: $thirdUrl)
                }
                
            }
        }
        
        Form{

                    DatePicker("Début", selection: $startDate)
                    DatePicker("Fin", selection: $endDate)
                    Spacer()
                    Toggle("Informer les acheteurs", isOn: $contactBuyer)
                    Toggle("Mettre en ligne", isOn: $isOnline)
                    
                }

@Claude31 in fact it can might works. I will try

@Claude31 so adapted your code to my project and I tested. Well done it's working. Thanks a lot. I am not familiar with such binding variables. Thanks for helping me out.

@Binding may seem complex but in fact pretty simple. And extremely important in SwiftUI. It is somehow equivalent to inout for a parameter.

• You have a State var in a view 1.
• you want to change this var in another view. 2
• You declare a Binding var in View 2 of the correct type, but not assigning value
• When you call view 2 from View 1, you pass the State var as parameter
• that will initialize the Binding var in View 2
• If you change value in View 2, that will propagate the change to State var (in fact you pass a reference of the State var).

Hope that's clearer. Good continuation.
