What's New in Code Runner
1.1.0
July 27, 2026
Interactive input is here. Programs that ask for input — input(), scanf, readLine — now stop and wait for you. Type your answer in the console, hit return, and the program picks up where it left off. No more end-of-input errors on your first exercise. Also in this release: • iPad: screen titles are no longer hidden behind the tab bar • Fixed layout spacing at the bottom of the editor on iPhone • More reliable saved snippets and run history across app reinstalls
