How can I convert CLLocationManager.magneticHeading to radians?

I am trying to covert the number of magneticHeading that I see, from 0 to 360, into radians so I can use CGPoint. However this code throws an error.

//Code to move on the X plane
let heading = self!.locManager.heading

let MagHeading = (heading?.magneticHeading)! * M_PI/180 //error

How can I covert this CLLocation value I get from the heading into a float so I can turn it into radians? The error is that heading is nil. Yet without the conversion it still produces values

Actual problem and your question are absolutely different. You need to handle optional variable there... but you mentioned conversion between double/float to radian

try this... at least your error will be gone.

if let heading = self.locManager.heading {

    let MagHeading = (heading.magneticHeading) * M_PI/180
    print("MagHeading - \(MagHeading)")

}  else {

   print("heading is nil")

}
