Introduction


Taking care of the app performance is one of the most important topics in iOS. All of us have faced apps that run smoothly without lagging or heating up your device. On the other hand, we have faced apps that lag a lot and cause memory pressure and overhead on the system. To build a successful app, you should take care of its performance and memory usage. Ensure that there isn't any memory pressure or memory leaks. The iOS system is smart enough to monitor the memory of all apps and kill any app that tries to cause memory pressure on the device. The system sends warning notifications to the app, before killing it to free some memory. In this chapter, we will cover some concepts of memory management and how to measure and optimize the performance of the app.
