compile my react native project on a mac

I have a fully functional react native project on github that already was built for iphone on a mac with my ios apple developer credentials. But my co-worker is not available and I don't have a mac for this version. I'll give you all the details. You build the app, and send it to me in gmail or via google docs. I'll need you to also send an invite to TestFlight or tell me how to do it. The whole thing took no more than 10 minutes. I'll need once tomorrow (Saturday July 28 night your time) and twice more in the next week or two. I'll need to identify you personally via a video call where you show me some identification and show me that you can be found on the web. (I will be giving you my credentials and I don't want them stolen).
