I wrote a custom plugin 3 years ago for a project which exported and worked fine using a version of Gideros in 2018. In a completely different project using same plugin I get the following error when I package the project in iOS.
Lua error:./Tools/export_ios.lua:156: Error: group GroupIOSSupport is not defined (yet)
Using version 2021.9
The same error appears when I compile the 3 year old project.
