Issue with loading file from disk - swift

Question

Ok so this one has had me scratching my head for a while.
I have a png file that I write out to disk. I get the data by:
let data = UIImagePNGRepresentation(scaledImage!)
let filename = getDocumentsDirectory().appendingPathComponent("\(record.uid!).png")
I do a try catch and everything seems to work. The resulting filename is:
file:///var/mobile/Containers/Data/Application/C6B796E8-2DB6-45A4-9B18-EF808B8CA3CA/Documents/580420d51800cd826a7e217c.png
The problem comes when I try to load that image back from the disk.
When I get a list of all files in the documents directory I get:
[file:///private/var/mobile/Containers/Data/Application/C6B796E8-2DB6-45A4-9B18-EF808B8CA3CA/Documents/580420d51800cd826a7e217c.png]
The only difference I can see is the 'private' part of the filepath. When I try to check to see if the file exists using the filepath I get back from appending the filename (the one without the private part) I get false.
What am I missing?

Swift 3/4 code
Let us assume the method getDocumentsDirectory() is defined as follows
func getDocumentsDirectory() -> URL {
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
let documentsDirectory = paths[0]
return documentsDirectory
}
In order to save the image
let data = UIImagePNGRepresentation(scaledImage!)
let filename = getDocumentsDirectory().appendingPathComponent("\(record.uid!).png")
try? data?.write(to: filename)
And your image is saved in Documents Directory
Now in order to load it back
let imagePath = getDocumentsDirectory().appendingPathComponent("\(record.uid!).png").path
let fileManager = FileManager.default
if fileManager.fileExists(atPath: imagePath){
print("Image Present")
//load it in some imageView
}else {
print("No Image")
}
