Mobile Continuous Integration at SoundCloud

Mobile Continuous Integration at SoundCloud

In the past two years at SoundCloud, we've shipped a brand new iPhone and iPad app and completely transformed the way we work. The team scaled from 3 to 10 developers, we've moved away from pull-requests and rely heavily on automated testing. As SoundCloud grew, its mobile application got more complex and the number of contributors expanded as well. Maintaining consistency and quality across teams is key to SoundCloud's continuing success. That's why we're building custom continuous integration solutions for our mobile apps.
