Choosing units with MeasurementFormatter

This is similar to a question I asked yesterday but the answer I got doesn\'t seem to work in this case.

I\'m getting altitude values in meters from Core Location. I

You just need to convert your UnitLength from meters to feet. You can also create a custom US measurement formatter to display it as needed:

extension Measurement where UnitType == UnitLength {
    private static let usFormatted: MeasurementFormatter = {
       let formatter = MeasurementFormatter()
        formatter.locale = Locale(identifier: "en_US")
        formatter.unitOptions = .providedUnit
        formatter.numberFormatter.maximumFractionDigits = 0
        formatter.unitStyle = .long
        return formatter
    }()
    var usFormatted: String { Measurement.usFormatted.string(from: self) }
}

Playground

let value: Double = 1839
let meters: Measurement = .init(value: value, unit: .meters)
let feet = meters.converted(to: .feet)
let formatted = feet.usFormatted
print(formatted)    // "6,033 feet"\n
