iOS has a handy formatter for file sizes. Here is an example of formatting at long into a readable string:

// Get file size
unsigned long long size = [[NSFileManager defaultManager]
attributesOfItemAtPath:path error:nil].fileSize;
NSLog(@"size: %@", @(size));

// Format file size to a readable string
NSString * fileSize = [NSByteCountFormatter stringFromByteCount:size
countStyle:NSByteCountFormatterCountStyleFile];
NSLog(@"fileSize: %@", fileSize);

Output:

size: 65346
fileSize: 65 KB
