WatchConnectivity transferFile method not working - ios

Question

I am attempting to transfer an image downloaded from facebook but for some reason my transferFile method has stopped working. The same code seemed to be working an hour ago and I cannot find what I have changed in order to cause it to stop working.
I am not getting an error from the delegate method nor is my log being called on the watch's side.
Here is how I am downloading my image and transfering.
func downloadImageToFile(urlString : String, completion: (NSURL?, NSError?) -> Void) {
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession.init(configuration: config)
let imageURL = NSURL(string: urlString)
session.downloadTaskWithURL(imageURL!, completionHandler:{(locationURL : NSURL?, response: NSURLResponse?, error: NSError?) in
if (error != nil) {
print("Error: " + (error?.description)!)
completion(nil, error)
}
else {
if let data = NSData(contentsOfURL: locationURL!) {
let documentsDirect = self.documentDirectory()
let saveLocation = documentsDirect.URLByAppendingPathComponent("GCD.png")
let saveWasSuccessfull : Bool = data.writeToURL(saveLocation, atomically: true)
dispatch_async(dispatch_get_main_queue(),{
if (saveWasSuccessfull) {
print("Save Was Successful")
completion(saveLocation, nil)
}
else {
completion(nil, error)
}
})
}
else {
print("Data Download Error")
}
}
}).resume()
}
func documentDirectory() -> NSURL {
let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
if let documentDirectory: NSURL = urls.first! as NSURL {
return documentDirectory
}
}
ViewController.swift
let downloader = WebImageDownloader()
downloader.downloadImageToFile(string, completion: { (transferLocation, error) in
if (error != nil) {
}
else {
self.session.transferFile(transferLocation!, metadata: nil)
}
})
func session(session: WCSession, didFinishFileTransfer fileTransfer: WCSessionFileTransfer, error: NSError?) {
if error != nil {
print(error?.description)
}
else{
print("Finished File Transfer Successfully")
}
}
Watch
func session(session: WCSession, didReceiveFile file: WCSessionFile) {
print("File Recieved on Watch")
dispatch_async(dispatch_get_main_queue()) { [weak self] in
if let data = NSData(contentsOfURL: file.fileURL) {
self?.photos.append(data)
self?.updateTable()
}
else {
print(file.fileURL)
}
}
}
Any ideas what is going on here? I have no errors logging to work with anything.
