Hanging clothes on a clothes line to dry only works you dont live somewhere with frequent rain
You put your clothes there, and the next day they are dry.
Other common solution is collapsible drying racks on your balcony: https://images.morele.net/i256/12998234_0_i256.jpg
Or just clothes lines (but usually people have some backup in case it rains).
I've never seen people use powered dryers for clothes. And we get our share of rain, and in the winter it gets to -20C sometimes.
If you have working ventillation you're fine either way. If not - you're not. In fact I'd expect worse problems if you evaporate that same water quicker, because there's less time for it to escape outside.
In contrast, my grandmother lives in a village with such incredible rainy seasons, that this has been a pain point as perpetual as the rain itself. For a few months in summer, the air is so humid that even unused clothes have trouble stay dry. Condensation appears on the wall, and nothing ever dries, no matter where you hang them; indoors, outdoors, doesn't make a difference. Sometimes, they have no dry clothes for weeks during summer.
