Hi,
My name is Colm and I'm new to freelancer. I'm really excited to get some projects under my belt and your app sounds like a really interesting one! I'd love to help you out with it and I'd be available to work on it full time until it is done.
Since you mentioned you are learning swift, I can really emphasise the comments in the code so you can follow along and give you pointers on how to source good quality tutorials to help you learn.
Your project description seems to have got trimmed so we'd have to clarify the exact spec but I think I have the gist of what you're after. If you're interested in working with me, please let me know and we can get stuck in!
Looking forward to hearing from you,
Colm
