Crash when opening context menu on Macbook Pro (designed for ipad)

[atambo]

So the context menu works fine on iphones/ipads but when I install my app on my Macbook Pro laptop it crashes immediately when opening the context menu. Here is the crash:

(I'm running the app using xcode and can grab whatever logs are helpful for you, this is just what shows up in the xcode console)

CLIENT ERROR: TUINSRemoteViewController does not override -viewServiceDidTerminateWithError: and thus cannot react to catastrophic errors beyond logging them
*** Assertion failure in -[UINSHostMenu initWithTitle:], NSMenu.m:411

It seems like the title prop on ContextMenu is required on MacOS. When I set the title prop to an empty string it stopped crashing.

Oh wow that's a great find!
