For work-around it seems that whilst Build seems to wants access to this function, the app doesn’t actually need it. So I’ve commented it out in iosLib using the old “ignore the issue and hope it goes away” approach to debugging.
Depending on what Xojo version you use (as you seem to be using the outdated version of iOSLib, not the content of AppleLib): Maybe it would be a workaround to use the 64 Bit savvy datatype of CGFloat to get around the pragmas?
I am not sure if statusbarframe is part of the new lib and I dont know when Ill find time to work on it in the future. But theres a reason all that stuff is on GitHub
