Summary:
Xcode does not find the correct MeasurementFormatter.string(from:) method for arguments of type Measurement.

Steps to Reproduce:
Paste this code into a playground or blank iOS project:

import Foundation

let distance = Measurement(value: 100, unit: UnitLength.kilometers)
let formatter = MeasurementFormatter()
let result = formatter.string(from: distance)

Expected Results:
Code compiles.

Actual Results:
// error: cannot invoke 'string' with an argument list of type '(from: Measurement<UnitLength>)'

Regression:
n/a

Notes:
See the attached playground.

This workaround works:
let result = formatter.string(for: distance)
