Summary:
Class properties are expected to be usable with dot notation. When using a custom getter name this does not work as expected.
Steps to Reproduce:
Given the following declaration:
@interface Foo : NSObject
@property (class, readonly, getter=sharedInstance) Foo *shared;
@end
... one expects the following to compile:
Foo *foo = Foo.shared;
... yet the compiler issues the following error:
property 'shared' not found on object of type 'Foo'
After changing the code to:
Foo *foo = Foo.sharedInstance;
... the error goes away.
This is not the expected behavior and not in line with instance properties.
Expected Results:
`Foo.shared` should compile without errors.
Actual Results:
`Foo.shared` does not compile.

Why would you expect this to work? You told the compiler that the getter is called "sharedInstance", not "shared".
