How do we clear an NSMutableData without using release and then re-alloc/init again to be used again? I was looking at resetBytesInRange to be set at zero but I am unsure of this. Anyone can help?

If you want an empty buffer:

[data setLength:0];

If you want to keep its size but set all the bytes to zero:

[data resetBytesInRange:NSMakeRange(0, [data length])];

Swift version of the setting all the bytes to zero:

data.resetBytes(in: NSRange(location:0, length:data.length))
