Still need to run `xcodebuild` at produce a binary.

expo build:ios actually.

My only need for a Mac with expo is for the upload. The apk file is taken care of with the command above.

I have an iPhone I use for development and testing. Bonus points is that expo is cross platform, so I can publish to google play with the same single code base too.

that command invokes `xcodebuild` behind the scenes. I'm very familiar with expo, and it's fragility and warts.

I'm glad it's working for you, so far, but try to do anything slightly interesting and you'll have problems.

You’re spot on!
