I can't put the categories variable anywhere in ConsoleList as I always get an error. I get: "Value of type '[AnyHashable : Any]' has no member 'category'"

In my content view preview, I get the two categories I want but they are duplicated by the amount of consoles the category belongs to and I just want one of each, anything I can do?
import SwiftUI
let Con :[consoleDetails] = consoleList.Consoles
struct ContentView: View {
var body: some View {
NavigationView{
List(consoleList.categories.sorted(by: {$0.key > $1.key}), id:\.key){con in
NavigationLink(destination: ConsoleSection(), label:{
Image(systemName: "folder.fill")
.scaledToFit()
.frame(height: 30)
.cornerRadius(4)
.padding(.vertical, 4)
VStack{
Text(con.key)
}
}).navigationTitle("appname")
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
The error is pretty simple. This is not a list of console categories it is a list of ConsoleDetails and you are showing the console category. That´s why you see doublets and triplets.
If you want to show a list of consoles and their respective names change:
Text(con.category)
to:
Text(con.consoleName)
If you really want a List of console categories you would need to group your ConsoleDetail into a Dictionary of type [String:[Consoledetail]]. This could be used to iterate in the list and show them.
Add this to your ConsoleList:
static let categories = Dictionary(grouping: consoles, by: {$0.category } )
Your ContentView then should look like this:
var body: some View {
NavigationView{
List(ConsoleList.categories.sorted(by: {$0.key > $1.key}), id:\.key){con in
NavigationLink(destination: ConsoleSection(), label:{
Image(systemName: "folder.fill")
.scaledToFit()
.frame(height: 30)
.cornerRadius(4)
.padding(.vertical, 4)
VStack{
Text(con.key)
}
}).navigationTitle("appname")
}
}
}
Remarks:
ConsoleSection will probably need the list of ConsoleDetail that is grouped in con in this case.You can´t access a nonstatic property from a static one. Either remove the static keyword from categories property or add it back to your consoles property.
E.g.:
static let categories = Dictionary(grouping: consoles, by: {$0.category } )
static let consoles = [...
Your ConsoleList should look like this:
struct ConsoleList{
static let categories = Dictionary(grouping: consoles, by: {$0.category } )
static let consoles = [
