Error when attempting to move item using FileManager

I have a few items that are saved to the documents directory. I currently need those to be moved programmatically to another directory. I created the new directory successfully, but it doesn't seem to be looking at that when using FileManager.default.moveItem.

Code used to created directory.

let path = getDocumentsDirectory().appendingPathComponent("Media").path

        do{
            try FileManager.default.createDirectory(atPath: path, withIntermediateDirectories: false, attributes: nil)

            print("\nDIRECTORY 'Media' CREATED")
        }catch {
            print("\nDIRECTORY 'Media' WAS NOT ABLE TO BE CREATED")
            print("ERROR - \(error)")
        }

I use this code to check my URL.

let mediaURL = getDocumentsDirectory().appendingPathComponent("Media")
print("\nMEDIA URL: \(mediaURL)")

Which outputs this.

MEDIA URL:file:///Users/joseph/Library/Developer/CoreSimulator/Devices/552B72BF-8929-40EE-A75B-4574D3D2918A/data/Containers/Data/Application/E168B872-6A1D-4D78-B460-D45194088E5B/Documents/Media/

Here is the code I'm using to move the items.

do{
    try FileManager.default.moveItem(at: url, to: mediaURL)

    print("\nFILE MOVED TO NEW MEDIA PATH SUCCESSFULLY")
}catch {
    print("\nCOULDN'T MOVE FILE TO NEW MEDIA PATH")
    print("ERROR - \(error)")
}

Here is the error I'm receiving for each item that I try to move.

COULDN'T MOVE FILE TO NEW MEDIA PATH ERROR - Error Domain=NSCocoaErrorDomain Code=516 "“image_5” couldn’t be moved to “Documents” because an item with the same name already exists." UserInfo= {NSSourceFilePathErrorKey=/Users/joseph/Library/Developer/CoreSimulator/Devices/552B72BF-8929-40EE-A75B-4574D3D2918A/data/Containers/Data/Application/E168B872-6A1D-4D78-B460-D45194088E5B/Documents/image_5, NSUserStringVariant=( Move ), NSDestinationFilePath=/Users/joseph/Library/Developer/CoreSimulator/Devices/552B72BF-8929-40EE-A75B-4574D3D2918A/data/Containers/Data/Application/E168B872-6A1D-4D78-B460-D45194088E5B/Documents/Media, NSFilePath=/Users/joseph/Library/Developer/CoreSimulator/Devices/552B72BF-8929-40EE-A75B-4574D3D2918A/data/Containers/Data/Application/E168B872-6A1D-4D78-B460-D45194088E5B/Documents/image_5, NSUnderlyingError=0x60000024fff0 {Error Domain=NSPOSIXErrorDomain Code=17 "File exists"}}

The media directory should be empty, as it is newly created, so the error I'm receiving is a bit confusing. It's also saying it's trying to move it to 'Documents', but it should be moving to 'Media'.What is causing this issue, and how can I resolve it? I'm just trying to move the items saved in 'Documents' to the new directory, 'Media'.

You can try to append the file name to the destination – GIJOW

You must append the file name to the destination URL. Per the docs:

The new location for the item in srcURL. The URL in this parameter must not be a file reference URL and must include the name of the file or directory in its new location. This parameter must not be nil.

Delete the old file if exist

let url = NSUrl(string: "...")
if NSFileManager.defaultManager().fileExistsAtPath(url.path!) {
    try! NSFileManager.defaultManager().removeItemAtURL(url)
}

Update:

Swift 5.1.2

let url = URL(string: mp3FilePath)
if FileManager.default.fileExists(atPath: url!.path) {
    try! FileManager.default.removeItem(at: url!)
}

This worked for me - Add the name of file too in destination path

let nameFile = (songPath as NSString).lastPathComponent
let fileDest = destinationDirectoryPath + "/" + nameFile
//Now move the song files
try fileManager.moveItem(atPath: sourceFilePath, toPath: fileDest)
