// FIXME: <rdar://problem/5106287> Only partial support for TextInputController has been implemented on iOS so far. We need to finish the implementation
// here to bring it up to parity with the Mac version (see TextInputControllerMac.m), and then reenable skipped iOS tests that use TextInputController.
