NSFileManager delete contents of directory

by

E.g. by using a directory enumerator:

NSFileManager *fileManager = [[NSFileManager alloc] init];
NSDirectoryEnumerator *enumerator = [fileManager enumeratorAtPath:path];    
NSString *file;

while (file = [enumerator nextObject]) {
    NSError *error = nil;
    BOOL result = [fileManager removeItemAtPath:[path stringByAppendingPathComponent:file] error:&error];

    if (!result && error) {
        NSLog(@"Error: %@", error);
    }
}

Swift

let fileManager = NSFileManager.defaultManager()
let enumerator = fileManager.enumeratorAtURL(cacheURL, includingPropertiesForKeys: nil, options: nil, errorHandler: nil)

while let file = enumerator?.nextObject() as? String {
    fileManager.removeItemAtURL(cacheURL.URLByAppendingPathComponent(file), error: nil)
}
