let name1 = xpcServiceName!
let name2 = name1 as NSString
let name3 = name2 as CFString
let diref = SMJobCopyDictionary( kSMDomainSystemLaunchd, name3 )
let jobDictionary = diref.takeRetainedValue() <--- I hope this is right
if jobDictionary == nil
{
println("Helper not running")
}
else
{
println("Helper JobCopyDictionary = \(jobDictionary)")
}
This works perfectly.
Thank you very much!
