Closing.

No need for specific methods, both knownRegions and developmentRegion are accessible

const knownRegions = pbxProject.pbxProjectSection()[pbxProject.getFirstProject()['uuid']]['knownRegions'];

const developmentRegion = pbxProject.pbxProjectSection()[pbxProject.getFirstProject()['uuid']]['developmentRegion'];

like what's done in previously ref sources
