Assigning NavigationLink to Images within Array in Swift UI

Question

I have an array of images that I am passing through a LazyVgrid.

I am wondering how I assign a NavigationLink to the Image names stored within the array, clicking icon1 navigates to page1, ect for all 8.

------ Swift UI -------

import SwiftUI

    struct Grid: View {
        var images: [String] = ["icon1", "icon2", "icon3", "icon4",
                                 "icon5", "icon6", "icon7","icon8"]
        
        var columnGrid: [GridItem] = [GridItem(.flexible(), spacing: 25), GridItem(.flexible(), spacing: 25)]
        
        var body: some View {
            LazyVGrid(columns: columnGrid, spacing: 50) {
                ForEach(images, id:\.self) { image in
                    Image(image)
                        .resizable()
                        .scaledToFill()
                        .frame(width: (UIScreen.main.bounds.width / 2.75 ) - 1,
                               height: (UIScreen.main.bounds.width / 2.75 ) - 1)
                        .clipped()
                        .cornerRadius(25)
                        
                        
                }
            }
        }
    }

For occasions like this I would prefer an enum that holds all related information. You also could do this with a struct the reasoning behind this stays the same.

enum ImageEnum: String, CaseIterable{ //Please find a better name ;)
    case image1, image2 
    
    var imageName: String{ // get the assetname of the image
        switch self{
        case .image1:
            return "test"
        case .image2:
            return "test2"
        }
    }
    
    @ViewBuilder
    var detailView: some View{ // create the view here, if you need to add
        switch self{           // paramaters use a function or associated
        case .image1:          // values for your enum cases
            TestView1()
        case .image2:
            TestView2()
        }
    }
}

struct TestView1: View{
    var body: some View{
        Text("test1")
    }
}

struct TestView2: View{
    var body: some View{
        Text("test2")
    }
}

And your Grid View:

struct Grid: View {
    
    var columnGrid: [GridItem] = [GridItem(.flexible(), spacing: 25), GridItem(.flexible(), spacing: 25)]
    
    var body: some View {
        NavigationView{ // Add the NavigationView
            LazyVGrid(columns: columnGrid, spacing: 50) {
                ForEach(ImageEnum.allCases, id:\.self) { imageEnum in // Iterate over all enum cases
                    NavigationLink(destination: imageEnum.detailView){ // get detailview here
                        Image(imageEnum.imageName) // get image assset name here
                            .resizable()
                            .scaledToFill()
                            .clipped()
                            .cornerRadius(25)
                    }
                }
            }
        }
    }
}

Result:
