NSFileManager filesize Incorrect for .xcodeproj File

Question

From the Mac Finder app I know that my file PicViewer.xcodeproj has a files size of 35,697 bytes. The code below gives me a file size of 160. I know the code works as it correctly tells me the file size of an Excel file.

I used the code from this stackoverflow question How can i get my file size in Objective-C with a minor change.

NSString *directoryPath = [@"~" stringByExpandingTildeInPath];
NSFileManager *fm = [NSFileManager defaultManager];
NSArray *array = [fm contentsOfDirectoryAtPath: directoryPath error:NULL];
for (NSString *filename in array) {
    NSError *attributesError = nil;
    NSDictionary *attributes = [fm attributesOfItemAtPath:[directoryPath stringByAppendingPathComponent:filename]
                                                    error:&attributesError];
    unsigned long long size = [attributes fileSize];
    NSString *filetype = [attributes fileType];
    NSLog(@"%@ %@ %llu", filename, filetype, size);
}

It also reports that the file type is NSFileTypeDirectory and not NSFileTypeRegular (and I suspect this is causing the file size to be reported incorrectly). For example:

Exercise Record.xlsx NSFileTypeRegular 637131

PicViewer.xcodeproj NSFileTypeDirectory 160

Any help would be greatly appreciated.

xcodeproj is a directory indeed, you can expand its contents in Finder using Show package content (or whatever, I do not use English MacOS) menu command, so in you want to calculate its size, you should do it recursively, for instance like that

Thanks, this helped. Is there anyway to distinguish between folders and package directories? – Keith Dec 30 '18 at 14:27
@Keith I do not think so, it is really just an ordinary directory which mimics to a file having a file-like dot-separated extension and an according app association to handle this – schmidt9 Dec 31 '18 at 09:30

getResourceValue: forKey: NSURLIsPackageKey worked for me in being able to tell the difference between a regular folder and a "package" folder packages from regular folders. – Keith Jan 03 '19 at 01:20
