I have a project where I retrieve json data from a remote api call and in my ForEach I filter it. I need to find out how many items are in the index that has been filtered:

ForEach(manager.filter({ "\($0)".contains(search) })) { index in

  HStack {
    Text(index.name)
   }

}

I tried to use a var and increment it, but since ForEach is a view, I can't use it there. Aftr my ForEach I want to display the count of the filtered array that is returned in index.

Text("Total names retrieved: \(someNumber)")

I have been searching online and haven't found a solution. Thanks

Hey there, try this out:

struct ContentView: View {
    ...

    var items: [Index/*or whatever your object name is*/] {
        manager.filter({ "\($0)".contains(search) })
    }

    var body: some View {

        ...

        ForEach(items) { index in
            HStack {
                Text(index.name)
            }
        }

        ...

        Text("Total names retrieved: \(items.count)")

        ...
    }
}

Extract the query into the top level of your view, and then you can count it easily outside of the ForEach.

Thanks. I had to change it slightly to make it work.

let items = manager.names.filter({ "\($0)".contains(search)})

I put this after the var body: some View {

Now I can get the count. Thanks for pointing me in the right direction.
