Conditions for warning:
|

1. the property is atomic
|
|
2. the current @implementation contains an @synthesize for the property
|
|
3. the current @implementation contains a hand-written setter XOR getter
|
|
4. the property is read-write
|
|
|
|
Cases marked WARN should warn one the following:
|
|
warning: Atomic property 'x' has a synthesized setter and a
|
|
manually-implemented getter, which may break atomicity.
|
|
warning: Atomic property 'x' has a synthesized getter and a

Cases not marked WARN only satisfy the indicated subset
