Entered CLLocationDegrees value yields erroneous value. Why?

Question

I'm trying to set a MKCircle coordinate and am having trouble creating the 'coordinate'.

I've tried setting specific CLLocationDegrees attributes but the entered numeral is not interpreted correctly.
For example, an entered '-37' yields 2.1974599073494367E-314.

Why is this happening; and how do I fix it?

(lldb) p lat
(CLLocationDegrees) $R0 = 2.1974599073494367E-314
(lldb) p long
(CLLocationDegrees) $R1 = 2.2149668507855847E-314

This appears to work:

let gLocationCoordinate:CLLocationCoordinate2D = CLLocationCoordinate2DMake(-37.813611, 144.963056)

(lldb) p gLocationCoordinate
(CLLocationCoordinate2D) $R2 = (latitude = -37.813611000000002, longitude = 144.96305599999999)

Answer 1

Looks like a problem with the debugger. As Martin notes, it works fine with println():

let lat : CLLocationDegrees = -37
let long : CLLocationDegrees = 144

println("Lat: \(lat) Long: \(long)")
// Output: "Lat: -37.0 Long: 144.0"

I'd file a radar against lldb.

Answer 2

I moved the code from viewDidLoad() to viewDidAppear() and it worked.

But need I do that?
