SwiftUI iterating through dictionary with ForEach

Question

Is there a way to iterate through a Dictionary in a ForEach loop? Xcode says

Generic struct \'ForEach\' requires that \'[Str

Answer 1

Here is how I implemented this:

struct CartView: View {
    var cart:[String: Int]

    var body: some View {
        List {
            ForEach(cart.keys.sorted()) { key in
                Text(key)
                Text("\(cart[key]!)")
            }
        }
    }
}

The first Text View will output the key which is a String. The second Text View will output the value of the Dict at that key which is an Int. The ! that follows this is to unwrap the Optional which contains this Int. In production you would perform checks on this Optional for a more safe way of unwrapping it, but this is a proof of concept.
