How to convert degrees to radians
Swift version: 5.6
Most users think about angles in terms of degrees from 0 to 360, but internally most of iOS works in radians so you’ll need to do some conversion. The equation to convert between the two is simple enough: multiply the number by Pi, then divide the result by 180.
To make things easier, drop in this function:
func deg2rad(_ number: Double) -> Double {
return number * .pi / 180
}You can now use deg2rad(90) to find 90 degrees in radians.
