i can't get data from api json i want to show the data of the table inside table using alamofire and swiftui

this is my first time working on integrate api so this is the structs of the data :

struct OsmItem: Codable {
    var success: Bool
    var message: String
    var resultData: [ResultDatum]
}

struct ResultDatum: Codable {
    var id: String
    var parentID: String?
    var published: Bool
    var title, shortDesctiption, longDescription, iconPath: String
    var iconName: String
    var subCategories: [ResultDatum]

    enum CodingKeys: String, CodingKey {
        case id
        case parentID = "parentId"
        case published, title, shortDesctiption, longDescription, iconPath, iconName, subCategories
    }
}

my goal is to show the data of the subcategories in the view i don't know how i only can show the of title and iconName this is my try

    LazyVGrid(columns: layout , spacing :10 , content: {
                ForEach(items?.resultData ?? [ResultDatum](), id: \.id) { item in
                    Button(action: {}, label: {
                        NavigationLink(destination: NewOfferStepFive().navigationBarTitle(Text("x")).navigationBarHidden(true)
                            .navigationBarBackButtonHidden(true) ) {
                                VStack {
                                    Image(item.iconName)
                                        .resizable()
                                        .frame(width: 100.0, height: 100.0)
                                        
                                        .scaledToFill()
                                    
                                    Text(item.title)
                                        .fontWeight(.bold)
                                        .foregroundColor(.black)
                                        .multilineTextAlignment(.center)
                                        .frame(width: 145, height: 43  )
                                        .font(.system(size: 17))
                                    
                                  
                                        
                                    }
                                }
                            } )
                }
                 
            })

any help of only showing the data of the subcategories ?
