Summary	0005221: Can't build from source on macOS 27 with Xcode 27
Description	We are building NoesisGUI from source and noticed with the update to the newest macOS 27, and with that Xcode 27 we can no longer build Noesis. NSToolkit writes MACOSX_DEPLOYMENT_TARGET = 10.13 into every generated macOS Xcode project. Building that project with Xcode 27 fails immediately: `error: The macOS deployment target 'MACOSX_DEPLOYMENT_TARGET' is set to 10.13, but the range of supported deployment target versions is 12.0 to 27.0.x. (in target 'Noesis' from project 'Noesis')` We tried bumping the target to 12.0 but started getting other errors like OpenGL deprecation warnings, and a compile error regarding a deprecated clipboard API but both could be "fixed" by adding some flags to ignore these errors, and then we could build from source again.

Platform	macOS
