@unlying it seems xcode does not see declarations of these functions anywehere. Is it possible you removed the Gideros header include "gideros.h" line from the file, or accidentally removed gideros.h files, or gideros lib?
I had something similar, removing arm64 from the build list fixed it. Does gideros make an arm64 binary?
