Is it possible to testing uitest (XCUI) when open url external browser?

Currently, I have to create automation ui test with XCUI and I have some action to open external browser by default is Safari.

I need to create some uitest's behavior like this.

1. Go to external browser when click my button.
2. Check is open correct url in browser (or just open browser) ?
3. Go back to our app with resume state.

Is it impossible to do that ?.
