I tested building commit http://hg.libsdl.org/SDL/rev/7adf3fdc19f3 on Mac Catalyst and found some issues:
* MTLFeatureSet_iOS_* enums aren't available under Mac Catalyst.
* OpenGL ES is unavailable under Mac Catalyst.
* Some Metal features are available under Catalyst but not iOS, such as displaySyncEnabled.
* Set Metal as the default renderer on Mac Catalyst
Attaching a patch that will make SDL2 build for Mac Catalyst.

Trying to integrate the latest SDL2 changes into our iOS project of Exult I've stumbled over the fact that when I added the static iOS library the public header files were copied to the archive of our project when you let Xcode build the archive.
This makes the archive invalid for upload to the AppStore Connect.
To fix this you need to delete the public headers from the build phase:
Open the xcode project, select the target "Static Library-ios", got to build phases, and in "headers" delete all the headers in the "public" group. This is safe to do as this actually just copies the public headers for some odd counterintuitive reason.
I think this needs to be done for all the library build targets but likely not for the framework targets.

When you unified the Xcode project file you forgot to add the iOS file (/src/misc/ios/SDL_sysurl.m) to the project file, so the dummy in that folder takes over and the call does not work.
Relevant commits:
http://hg.libsdl.org/SDL/rev/c86bbf75f55e (SDL_OpenUrl enabled for macOS/iOS)
http://hg.libsdl.org/SDL/rev/282c3dc1cf65 (and following: unified Xcode project files)
Adding an ios group in the misc group of the project file and then adding /src/misc/ios/SDL_sysurl.m to it fixes the problem.

This patch adds support to the GameController framework on macOS Big Sur and later, adding support for MFi controllers as well as rumble support for PS4 and Xbox One. There is some code to make sure that the IOKit joystick handler doesn't include two controllers at once.
While the GameController framework is present in earlier versions of macOS, there was no public, approved way of checking if a specific IOHIDDevice is a controller that GameController could handle. This was changed in Big Sur.
