Area: Foundation Summary: The MeasurementFormatter doesn't format UnitTemperature the same way. UnitStyle .long - shows always the same format UnitStyle .medium - shows different formats - "x °C", "x°C" or "x °C" "x °F" UnitStyle .short - shows different formats - "x°", "x°C", "x°F" Steps to Reproduce: 1. Create a sample application 2. Code let measurement = Measurement<UnitTemperature>(value: 10, unit: .celsius) let formatter = MeasurementFormatter() let numberFormatter = NumberFormatter() numberFormatter.numberStyle = .none formatter.numberFormatter = numberFormatter formatter.unitStyle = .short let degree = formatter.string(from: measurement) print(degree) 3. Run the application with different Region, Language and TemperatureUnit settings. 4. See different results Expected Results: All unitStyles should be formatted identically otherwise it's not possible to define a specific user interface for the user. Actual Results: UnitStyle .long - shows always the same format UnitStyle .medium - shows different formats - "x °C", "x°C" or "x °C" "x °F" UnitStyle .short - shows different formats - "x°", "x°C", "x°F" Version: iOS 10.3.1 (14E304) Notes: It would be awesome to have a variable to get the user setting for temperature unit. It's only possible to get the value with private api, then the formatter wouldn't be needed it would be possible to convert the UnitTemperature with Measurement convert(to:) method. Configuration: Any iOS 10.3 devices and possible earlier
