How to launch an SDL3 game via a launcher on iOS

[lsl330]

I want to implement a launcher on iOS that runs SDL3 games. I can successfully call my cpp_main function from the launcher

Cpp
#define SDL_UIKitRunApp(ARGC, ARGV, MAIN_FUNC) SDL_RunApp(ARGC, ARGV, MAIN_FUNC, NULL)
int cpp_main(int argc, char* argv[])
{
return SDL_UIKitRunApp(argc, argv, SDL_main);
}
int SDL_main(int argc, char* argv[])

"When I build the SDL3 project as a standalone game, it launches correctly. However, when I try to launch it via a Swift launcher, I get the error: Thread 1: "There can only be one UIApplication instance." After researching online, I found that launching SDL for display from a launcher is quite complex. Therefore, I'd like to ask: is there a simpler way to achieve this?"
