| objc-missing-hash |
| ================= |
| |
| Finds Objective-C implementations that implement ``-isEqual:`` without also |
| appropriately implementing ``-hash``. |
| |
| Apple documentation highlights that objects that are equal must have the same |
| hash value: |
| https://developer.apple.com/documentation/objectivec/1418956-nsobject/1418795-isequal?language=objc |
| |
| Note that the check only verifies the presence of ``-hash`` in scenarios where |
| its omission could result in unexpected behavior. The verification of the |
| implementation of ``-hash`` is the responsibility of the developer, e.g., |
| through the addition of unit tests to verify the implementation. |
