Enable backwards compatibility when compiling with Xcode 14 (#329)

* Enable backwards compatibility when compiling with Xcode 14 This will still mean that the bug addressed in #314 will persist, but will allow consumers bound to older Xcode versions to continue to update the rest of the codebase and its dependencies * Add end-of-file new lines * Safe-guard usage as well
