Hi! I have the following expandable list. kpiValue is a double but I only want to display it with 2 decimal places (in fact it a revenue number) How do I do this in an expandable list specifier: "%.2f does not work. I get the error: Trailing closure passed to parameter of type 'FormStyleConfiguration' that does not accept a closure at the top of my form.

 // "Month to Date" Expandable list
                                   let itemsMthAv: [BookmarkMthAv] = [.kpiListMthAv]
                                   List(itemsMthAv, children: \.items) { row in
                                               HStack {
                                                   Image(systemName: row.icon)
                                                   Text(row.name)
                                                       .font(.subheadline)
                                                       .foregroundColor(.purple)
                                                   Text(row.currency)
                                                       .font(.subheadline)
                                                       .foregroundColor(.green)
                                                  // Text(row.kpiValue, specifier: "%.2f" )
                                                        Text(row.kpiValue)
                                                       .font(.subheadline)
                                                       .foregroundColor(.green)
                                               }
                                           }

Try

Text("\(row.kpiValue, specifier: "%.2f")")

Hello, Yes I tried that but sadly no progress.

Whan I make that change I get a compile error:

FormStyleConfiguration' that does not accept a closure at the top of my formI dont understand why, I can only assume that using specifier breaks something else in the form.

ah. I re read your response. My bad! Your syntax is different!. I will try this. Thank you.

Sadly no success: Instance method 'appendInterpolation(_:specifier:)' requires that 'String' conform to '_FormatSpecifiable'

Tried this and works fine

struct ContentView: View {
    let kpiValue = 2.34567

    var body: some View {
        VStack {
            Text("\(kpiValue, specifier: "%.2f")")
        }
        .padding()
    }
}

Are you sure that kpiValue is a Double not a String because this get the error

struct ContentView: View {
    let kpiValue = "2.34567"

    var body: some View {
        VStack {
            Text("\(kpiValue, specifier: "%.2f")")
        }
        .padding()
    }
}

if so you might want to do something like this

struct ContentView: View {
    let kpiValue = "2.34567"

    var kpiValueNumber: Double {
        guard let kpiValue = Double(kpiValue) else { return 0.0 }
        return kpiValue
    }

    var body: some View {
        VStack {
            Text("\(kpiValueNumber, specifier: "%.2f")")
        }
        .padding()
    }
}
