CH 13: Binary Tree Challenge 2, `deserialize` function is not working

I was trying to solve challenge problems. After hours of try, I still can’t solve this.
So, I peek the final project to see how this function works, But it’s not working :frowning:
the deserialze function result a compile error in the playground.

I wondering is there any wrong for my books?

Hey, just wanted to let you know that this is indeed a bug!

The final project was missing some code, but the solutions should be correct. We’ll be fixing this in the upcoming Swift 5.1 update.

For now, you’ll need to follow the instructions in the solutions page. Sorry for the inconvenience!

Thanks for replying back
