Ok - I acknowledge this is super nitpicky, and I didn’t even knew I cared until it caught me off guard every time I’ve encountered it, but I think your buttons are backwards in the dialogue for choosing a custom response when reporting a post.

Per Apple’s HIG:

Place buttons where people expect. In general, place the button people are most likely to choose on the trailing side in a row of buttons or at the top in a stack of buttons. Always place the default button on the trailing side of a row or at the top of a stack. Cancel buttons are typically on the leading side of a row or at the bottom of a stack.
