I have been working on an application in Xcode for a while now and had previously detected a lot of memory leaks using Instruments. Fast forward a few months and I have added threading to my application and Instruments will not show any memory leaks even though it has a growing memory footprint.
Does Instruments not detect memory leaks in threads I create? What could be the reason for these leaks flying under the radar?
Leaks just means objects for which there is no references to said objects. If your app is allocating memory and filling, say, a cache or some global dictionary or whatever, it’ll grow unbounded and show nary a leak.
You’ll probably want to use Heapshot based analysis to track it down.
