Getters for fields defined with uppercase names do not work

Using a thrift file such as:

struct Foo {
  1: required i32 Bar;
  2: required i32 baz;
}

The generated Objective-C object, "baz" will have working getters but "Bar" will not. For example, after setting bar to 5 and baz to 9, I get the following output depending on the syntax:

[foo bar] => 0
[foo Bar] (private method invoked by performSelector) => 5
foo.bar => 0
foo.Bar => 0
foo.baz => 9

The problem is that the generated header specifies a lowercase getter:

@property (nonatomic, getter=bar, setter=setBar:) int32_t Bar;

Whereas the .m file uses uppercase:

- (int32_t) Bar {
  return __Bar;
}

When the Objective-C compiler sees that there is no lowercase getter implementation provided, it automatically generates one (this is supposed to be a convenience of the @property syntax). So effectively, two getters are defined: a lowercase one that does not work, and an uppercase one that does work but is private.

As a workaround one can define all their fields beginning with a lowercase letter, if possible.
