Hi,
I believe the code signing part is covered by existing CMake xcode support, as
it is also for macOS.
The support for fat binaries is something I don't have hands-on experience, but
the upstream documentation suggests support for it on macOS, iOS, etc.:
https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_ARCHITECTURES.html
This appears to result in multiple -arch parameters on the command line when
calling the compiler.
I'd love to learn more about how fat binaries can be implemented and if the
above is the right direction or if a completely different approach is needed.
Simon

Sorry, but the iOS should be properly supported before making the final
decision.
Building something on macOS is easy, building smth for iOS is harder. From the
top of my head it is code signing and building "fat" binaries that should be
tested as a proof of concept.

Hi,
Regarding PCH, it seems that right now it would be easiest to include something
like https://github.com/sakra/cotire . Patches are welcome to integrate this or
alternatively work with upstream CMake for a built-in solution.
Regarding iOS/tvOS/watchOS, my understanding is that CMake upstream has landed
basic support from a toolchain perspective and welcomes contributions to make
it better. I understand that Alexandru has been playing with making a Qt build
with it and supplying third-party libraries via vcpkg, but I think that's
nothing beyond the scope of experiments. So similarly here, contributions are
welcome :)
Those two aspects are also a driver for increasing the visiblity of the CMake
port, in order to invite contributors to help. Yet I feel that they don't
represent show-stoppers from a decision making point of view. I'm confident
that if others in the C++ community are able to build apps for iOS with CMake,
then we will also be able to build Qt for it.

Any news about iOS/tvOS/watchOS and PCH?
Cheers,
