Off-cycle Swift compiler mentorship

Hi, I didn't know that there was a mentorship program until now :cry:. I would love to spend the next 2 months of my winter holiday working on the Swift compiler. I enjoy programming in Swift - so I would love to contribute, but I'm would appreciate a bit of guidance (e.g. issues I can work on - there are a bunch but they are usually already taken or not triaged, how to navigate the codebase, etc)

Just a shot in the dark - would anyone be willing to mentor me?

I'm a year 2 Computer Science student from Singapore. I'm quite familiar with Swift - I've made several advanced Mac apps (https://homerow.app, https://pronotes.app). I don't have professional experience in compilers, but I have a lot of experience wrangling with complex tree data structures in my side project Homerow.
