I had an issue with SDL_Delay() in MacOS 10.14.6

Question

It seems that the SDL_Delay() has some problem in macOS, instead of that we can use:

bool is_running = true;
SDL_Event event;
while (is_running) {
    while (SDL_PollEvent(&event)) {
        if (event.type == SDL_QUIT) {
            is_running = false;
        }
    }
    SDL_Delay(16);
}

But what should I use when I want my program to stop for 2 seconds.

I found the answer: https://discourse.libsdl.org/t/sdl2-cant-see-the-window/25835

Ok, I found the issue. The window wouldn't show up on OS X unless I had an event loop going (prior I had an SDL_Delay call).
