While, the review process is ongoing, I looked at the patch. It is generally very good and closely follows the convention for
doing auto boxing of other types. I have few general comments to make.
- It is important to have a complete IRGen tests for all the supported boxed items.
- CGPoint, CGSize, CGRect are iOS APIs only. But I haven’t been able to find their APIs in
the later version of iPhone SDKs. If they have been removed recently, then we should make sure to check
the deployment target and issue proper diagnostics if need be. This is generally the case for all the APIs.
If we are going to use auto boxing, then we need to make sure the APIs available in earlier (or later) versions
of the SDKs.
- Have you though of supporting other item types?

Any C pointers
One code comment: getNSValueFactoryMethod has two default arguments but do not have non-default value.
