How to beat Swain as Yuumi: the early game

Levels 1-5 are firmly yours: Swain has no point-and-click lockdown, only the slow W zone and the linear E root, both easy to sidestep while attached. Poke him relentlessly with empowered Q and keep your ADC topped, building a health lead. Every whiffed E is a free trade window for you. His root plus the drain is the only thing that ends this lane, so keep your carry off the pull's path. Stay attached, keep the heal-speed for the moment it lands, and aim the missile only in the gaps his cooldowns leave rather than continuously.
