Finding file's size

In my iPhone app I am using the following code to find a file's size. Even though the file exists, I am seeing zero for the size. Can anyone help me? Thanks in advance.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *URL = [documentsDirectory stringByAppendingPathComponent:@"XML/Extras/Approval.xml"];

NSError *attributesError = nil;
NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError];

int fileSize = [fileAttributes fileSize];


Try this;

NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError];

NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
long long fileSize = [fileSizeNumber longLongValue];

Note that the fileSize won't necessarily fit in an integer (especially a signed one) although you could certainly drop to a long for iOS as you'll never exceed that in reality. The example uses long long as in my code I have to be compatible with systems with much larger storage available.

One liner in Swift:

let fileSize = try! NSFileManager.defaultManager().attributesOfItemAtPath(fileURL.path!)[NSFileSize]!.longLongValue

If you have a URL (NSURL, not a String), you can get the file size without a FileManager:

 let attributes = try? myURL.resourceValues(forKeys: Set([.fileSizeKey]))
 let fileSize = attributes?.fileSize // Int?

Swift 4.x

do {
    let fileSize = try (FileManager.default.attributesOfItem(atPath: filePath) as NSDictionary).fileSize()
    } catch let error {

Get the file size in MB Try This code for swift

func getSizeOfFile(withPath path:String) -> UInt64?
    var totalSpace : UInt64?

    var dict : [FileAttributeKey : Any]?

    do {
        dict = try FileManager.default.attributesOfItem(atPath: path)
    } catch let error as NSError {

    if dict != nil {
        let fileSystemSizeInBytes = dict![FileAttributeKey.systemSize] as! NSNumber

        totalSpace = fileSystemSizeInBytes.uint64Value
        return (totalSpace!/1024)/1024
    return nil
