Cocoa - NSFileManager removeItemAtPath not working

Question

I'm trying to delete a file, but somehow nsfilemanager will not let me do this. I use the file in one line of code, but as soon as this action is completed, I want the file to be deleted. I registered an error code and a message, and I get an error code: 4 and a message:

"text.txt" could not be removed

Is there a way to fix this error “cleanly” (without any hacks) so that the apple accepts this application in its Mac App Store?

EDIT:

This is what I use:

[[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL];

Thank,

Kevin

swift. - fileManager.removeItemAtPath , Manager.removeItemAtPath(filePath) fileManager.removeItemAtURL(fileURL), .

    let fileManager = NSFileManager()
    let documentsFolderUrl = fileManager.URLForDirectory(.DocumentDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: false, error: nil)

    let soundURL = documentsFolderUrl!.URLByAppendingPathComponent(recording.path)
    let stringTrimmedFilePath = "trimmed_\(recording.path)"
    let trimmedSoundURL = documentsFolderUrl!.URLByAppendingPathComponent(stringTrimmedFilePath)
    var error: NSError?
    fileManager.removeItemAtURL(trimmedSoundURL, error: &error)

   NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
        NSString *documentsDirectoryPath = [paths objectAtIndex:0];

    NSString *databaseFile = [documentsDirectoryPath stringByAppendingPathComponent:@"text.txt"];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    [fileManager removeItemAtPath:databaseFile error:NULL];
