Build Error for XCODE 9, sierra 10.12.6, corona 2017.3160

i advise you, to try my remedy. compile the launchscreen with xcode 9. that was my fix. i did not try anything else. since you said its a similar issue, im thinking the fix might be the same. but im not sure, you wont know for sure unless you try.

I’m not sure how to do that exactly, as I have never had to do it before.

Something like this?

https://docs.coronalabs.com/guide/distribution/launchFile/index.html

yes exactly that, thats the guide that i followed for xcode 8, you need to do that for xcode 9 and the new os and latest corona build. goodluck!

Thanks, that did the trick. For those who come across this the Assets.xcassets -> Application.appiconset -> Contents.json file has additional icons that are not in the Corona file. Here is the updated .json file:
