Speaker: Patrick Balestra & Erick Camacho We all share the pain of long compilation times. In this session, Patrick and Erick discuss how the soon-to-be open source tool, XCMetrics, has improved the developer experience for iOS engineers at Spotify and enabled teams to make data-informed decisions about their projects. Along with collecting detailed Xcode build metrics, attendees will get a demo of how developers can find accurately collected build times at a file, or even a function level, warnings, errors, and their machine specifications in order to understand and track the developer experience. About the Speakers: Patrick is a Senior iOS Engineer at Spotify in Stockholm where he works on build systems and developer experience. Erick works as a Senior iOS infrastructure engineer at Spotify taking care of the iOS developer experience. Event URL: https://iosconf.sg
