With the recent updates from Apple, only the apps built with iOS SDK version 12x will be accepted for apple store and it has started to throw warning and occassionally reject the builds if they were complied with iOS 11x.
I was using ArcGIS AppStudio Cloud make tool and it is always building to iOS 11.3.
I've found this iTunes Connect: SDK version issue but even with using latest version of AppStudio (3.2.79) and removing item from local and cloud, also doing a clean build, the problem still remains the same. (see attachments)
Does anyone have any pointers ? Is local build the only way to go as of now ?
