I think the convention is to UpperCamelCase these.

[lpromero, 2017/03/29 11:38:15]

I'd even omit the "matcher" in all these. It makes the call site shorter and not
more difficult to read.

Done.

[Moe, 2017/03/29 17:04:09]

Done.

Instead of having a different ID for both selected and unselected, you could
simplify by checking the UIAccessibilityTraitSelected. That way I think you
could remove the logic of two accessibility identifiers.

TIL! Done.
