When ARC was introduced in Objective-C, memory management become much less of an issue, but you can still create issues especially with holding objects longer than needed.
Here’s an open source iOS debug tool that allows you to monitor the memory heap from within your app and quickly identify any memory issues called HeapInspector from tapwork. With heap inspector you can get data from running objects that includes the reference history, detailed information, and screenshots.
You can also take snapshots to compare the heap before you started recording so you can quickly identify any leaking objects, unneeded objects that are still alive and more.
