At DoorDash we are consistently making an effort to increase our user experience by increasing our app’s stability. A major part of this effort is to prevent, fix and remove any retain cycles and memory leaks in our large codebase. In order to detect and fix these issues, we have found the Memory Graph Debugger to be quick and easy to use. After significantly increasing our OOM-free session rate on our Dasher iOS app, we would like to share some tips on avoiding and fixing retain cycles as well as a quick introduction using Xcode’s memory graph debugger for those who are not familiar.
