Starting with OS X 10.10 and iOS 8.0, settings are also accepted (but not returned) in the following simplified forms:
An OpenType setting can be either an array pair of tag string and value number, or a tag string on its own. For example: @[ @"c2sc", @1 ] or simply @"c2sc". An unspecified value enables the feature and a value of zero disables it.
An AAT setting can be specified as an array pair of type and selector numbers. For example: @[ @(kUpperCaseType), @(kUpperCaseSmallCapsSelector) ].
