Unable to build on Catalyst

[marcosrdz]

When attempting to build a Mac Catalyst app using RealmJS 10.4.1 I get this error:

d: warning: directory not found for option '-L /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.3.sdk/System/iOSSupport/usr/lib /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/maccatalyst'

We currently don't have support for Catalyst but I believe we can add it relatively easy.

Mostly an internal note (or partial todo list):

• Use the maccatalyst.toolchain.cmake instead of ios.toolchain.cmake in https://github.com/realm/realm-js/blob/master/scripts/build-ios.sh#L39
• Either expand build-ios.sh or create new tool to drive the build process
• Create cmake/maccatalyst.toolchain.cmake similar to cmake/ios.toolchain.cmake
• Include Catalyst in RealmJS.podspec

Any updates?

We haven't had a breakthrough yet but we are working on it. It turns out that building for Catalyst using CMake isn't trivial.
