XcodeWarnings.xcconfig is an Xcode configuration file that lists all warnings and static analyzer

settings present in Xcode 15 and Xcode 16. Comment out any settings that won't help your project.

Accompanying blog post: [Xcode Warnings: Turn Them Up to Eleven!](https://qualitycoding.org/xcode-warnings/)

All warnings are enabled, with these exceptions:

**Commented Out by Default**

- "Pedantic Warnings" (`GCC_WARN_PEDANTIC`) isn't enabled because ordinary interaction with Apple's

  libraries makes it unhappy.

- "Treat Warnings as Errors" (`GCC_TREAT_WARNINGS_AS_ERRORS` and `SWIFT_TREAT_WARNINGS_AS_ERRORS`) aren't enabled because when

  experimenting with code, I sometimes temporarily comment out a line which uses a variable — which

  triggers the "Unused Variables" warning.

- "Unused Parameters" (`GCC_WARN_UNUSED_PARAMETER`) isn't enabled because it's not unusual to

  provide a method required by Apple's frameworks that ignores a parameter.

**Not Even Included**

- "Implicit Synthesized Properties" (`CLANG_WARN_OBJC_MISSING_PROPERTY_SYNTHESIS`) isn't included

  because in all likelihood, you don't need to be backwards compatible with non-modern Objective-C.

- "Disable Safety Checks" (`SWIFT_DISABLE_SAFETY_CHECKS`) isn't included in order to keep runtime safety checks when optimizing.

- "Inhibit All Warnings" (Apple Clang) and "Suppress Warnings" (Swift) aren't included because they're the opposite of our goals for this configuration.

## Static Analyzer

The Static Analyzer is also completely enabled, including "Deep" analysis during the Build action.

If that's too slow, comment out `CLANG_STATIC_ANALYZER_MODE` to restore faster "Shallow" analysis.
