expo eject - can't build iOS with latest version

Sure. I had an unresolved issue here: Assets not Uploaded on Publish SDK30 - #2 by adamjnav

I have this problem only on ExpoKit as far as I can tell. And it may be related to my other issue: Include local CSS/JavaScript in WebView, which hasn’t received a response. (Trying to include local JS and CSS in a webview without detaching). It works before I publish, but as soon as I publish I can no longer reach local files in Webview. I was able to solve that by detaching and creating new assets folders in Android Studio and Xcode, but wasn’t a great solution.
