You can use an empty NavigationLink and bind your navigation flag or destination to your Button .

struct FirstView: View {
    
    @State var navigationFlag = false
    
    var body: some View {
        NavigationView {
            VStack {
                Text("First View")
                
                Button(action: {
                    self.navigationFlag = true
                }, label: {
                    Text("navigate")
                })
                
                NavigationLink(destination: SecondView(),
                               isActive: self.$navigationFlag,
                               label: {
                                EmptyView()
                               })
            }
        }
    }
    
}

struct SecondView: View {
    
    var body: some View {
        Text("Second View")
    }
    
}
