Files in tmp directory still taking up space after deletion ios - ios

Question

I am saving media data to the iPhones tmp directory and after it is no longer needed I delete all the files. However I have noticed in my phones settings menu, under storage that my applications memory is increasing every time I save a new file and then later delete it. I am pretty sure the files are being removed because if I try to delete the same file again it throws an exception that it doesn't exist. Here is my code for deleting everything in tmp:
let content = try FileManager.default.contentsOfDirectory(atPath: NSTemporaryDirectory())
for path in content {
let fullPath = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(path)
try FileManager.default.removeItem(atPath: fullPath.absoluteString)
}
The weird thing is that sometimes after not using the application and coming back the memory goes down, keyword being sometimes. Am I doing something wrong and/or is there anything else I can do to minimize the memory footprint of my application in regards to the tmp folder?

Answer 1

It turns out passing it a NSURL vs string was the solution, now the files are definitely being deleted:
for path in content2 {
let filePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(path)
try FileManager.default.removeItem(at: filePath!)
}
