This code crashes for me with SwiftFoundation, but not with Darwin Foundation:
/// Turn `NSData` into `dispatch_data_t`
internal func createDispatchData(data: NSData) -> dispatch_data_t {
let c = data.copy() as! NSData
let info = Unmanaged<NSData>.passRetained(c)
let destructor = {
info.release()
}
let q = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)!
return dispatch_data_create(c.bytes, c.length, q, destructor)
}
I'm not sure what to look for. The values being passed into dispatch_data_create() look sane.
Is this a red herring?
