Make Swift Assume Degrees for Trigonometry Calculations

Question

Is it possible to change a setting, property, etc in Swift for iOS so that it assumes degrees for trigonometry calculations rather than radians?

For example si

Answer 1

You can define global functions that return the sin of a degree value. Just place the function in a swift file outside of any class.

func sind(degrees: Double) -> Double {
    return sin(degrees * M_PI / 180.0)
}

So anywhere in your project you can just use:

sind(90) // Returns 1
