[PyQt] PyQt 5.5: iOS Build undefined symbols: QMacCocoaViewContainer

[David Morris]

I am building an iOS application using Qt 5.3.2 & PyQt 5.3.2.  This works.

However, if I build the app using Qt 5.5 & PyQt 5.5.1 (developer
snapshot), I get a large list of undefined symbols when the
application links, all related to QMacCocoaViewContainer.

I am guessing QMacCocoaViewContainer is related to OSX only and should
not exist on iOS.  Searching for a solution, it appears this was added
to PyQt in 5.4.1 or 5.4.2.

How can I either link in the missing library or remove it from the iOS build?

Here is the full list of undefined references for the arm64 build:
