This is my blog. I also have a website thing.

Always Initialize to Nil

Posted on

Here's an excerpt from a great blog post on why you should always initialize your variables to nil.

“Always initialize your object variables to nil, no matter what, because some day they may be captured by a block and if they contain junk when the block is copied you’re going to crash.”

It's just good practice, but this really sums it up. Thanks for the write up Ryan Perry!
