Apple said this year’s Swift Student Challenge winners built app playgrounds focused on accessibility, presentations, flood evacuation, and music education.

Apple reported 350 winning submissions from 37 countries and regions in this year’s Swift Student Challenge. Apple said 50 Distinguished Winners will attend a three-day WWDC experience at Apple Park in June.

Apple stated that many winners based their projects on community needs and accessibility. Apple profiled four Distinguished Winners in its May 7 Newsroom article.

Apple said Gayatri Goundadkar, 20, built Steady Hands for artists with tremors. Apple reported the app used Apple Pencil data, PencilKit, and Accelerate to analyse strokes and remove tremor effects.

Apple said Anton Baranov, 22, built a pitch coach for presentation practice. Apple reported that the app used Apple’s Foundation Models framework for real-time feedback and post-session summaries.

Apple stated that Baranov released Pitch Coach on the App Store in early March. Apple said the app recorded more than 6,000 organic downloads.

Apple said Karen-Happuch Peprah Henneh built Asuo for people in flood-prone communities. Apple reported that the app provided real-time routing, used historical flood data, VoiceOver labels, and voice alerts.

Apple said Yoonjae Joung, 21, built LeViola to help users learn and play the viola. Apple reported the app used hand-joint analysis, arm-angle tracking, Create ML, and Core ML.

Apple stated the annual challenge asked students to build original app playgrounds with Swift. Apple said the programme supports students developing apps and technology projects.
