How can I rearrange decks on Anki IOS?

I want to rearrange decks on anki iOS.
Example my spanish deck is in under another deck but I want to move it to another empty deck without ruining my progress.

If you swipe across a deck, you can pick the rename option, then adjust the name of the parent deck. Since drag & drop is not currently supported, if you need to move lots of decks, I’d recommend you do so using the computer version for now.
