Any Other Way to Startup SDL on iOS?

SDL Development
1

As we all know that, using SDL_UIKitAppDelegate is the only official way to boot SDL on iOS.
However, I have an app based on SwiftUI which doesn’t allow me to do that.
Is there any way to boot it normally?
Now I using such functions, and the sound of game works well.
However there are no SDL_window, and only a black screen present.

Function:

    SDL_ClearError()
    SDL_AddHintCallback(SDL_HINT_IDLE_TIMER_DISABLED,SDL_IdleTimerDisabledChanged, nil);
    SDL_SetMainReady()
    SDL_Init(SDL_INIT_VIDEO.magnitude)
    FileManager.default.changeCurrentDirectoryPath(tmpURL)
    
    SDL_iPhoneSetEventPump(SDL_TRUE)
    DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
        UIApplication.shared.delegate?.applicationDidBecomeActive?(UIApplication.shared)
    }
    let existStatus = launcher_main(customArgc, customArgv)
    SDL_iPhoneSetEventPump(SDL_FALSE)
    return existStatus

There also an error in Xcode log, however I couldn’t understand it.
