Answer 1

As of iOS 10, there's a new Measurement class which makes converting distances a snap.

Here's an extension to convert distances:

extension Double {
  func convert(from originalUnit: UnitLength, to convertedUnit: UnitLength) -> Double {
    return Measurement(value: self, unit: originalUnit).converted(to: convertedUnit).value
  }
}

Example usage:

let miles = 1.0
let metersInAMile = miles.convert(from: .miles, to: .meters)

let mileInFeet = 5280.0
let feetInAMile = mileInFeet.convert(from: .feet, to: .miles)

let marathonInFeet = 138_435.0
let milesInMarathon = marathonInFeet.convert(from: .feet, to: .miles)
let kmInMarathon = marathonInFeet.convert(from: .feet, to: .kilometers)

let inch = 1.0
let centimetersInInch = inch.convert(from: .inches, to: .centimeters)
