Originally assigned to: @NghiaTranUIT on GitHub.

Hi Nghia,

I faced with the situation when device/simulator starts consuming huge memory amount and hangs as a result. I don't know why this happens, because this is not a persistent issue and it appears from time to time (I don't see specific cause).

This is the evidence from Debug navigator:

And as per profiler looks like getAllClasses is responsible for that:

so there are more than 40 000 calls of it...

device iOS version: 14.6 (reproduced for simulators as well)
Xcode: Version 12.5.1 (12E507)

please let me know I should provide some more details

Thanks,
Andrew

Hey @andy3a thanks for your report.

Runtime.getAllClasses() should only be executed once when the app is starting. If it executes multiple times (as your screenshot), I suppose there is a bug somewhere.

I will replace it with a better version and send you a beta this week 👍

Just wondering:

Are you using any 3rd-party networking library? such as AFNetworking, or Alamofire? If yes, what version?

I would like to reproduce it in my machine 💻

thanks for you effort @NghiaTranUIT

successfully deployed the commit.

I'll need to use it for couple days to see if the issue can be reproduced unless you know how to reproduce the situation when the issue appeared in previous version

cheers

It's odd that this array of AnyClass doesn't release when it exits the function 🤔

@andy3a Please try this commit 29088bc9b752498cdb74051c962855f2de77e52a, which I disable the Method Swizzling on NSURLConnection.

Hi @NghiaTranUIT,

I'm sorry but the issue has been reproduced again.

... for the latest fix provided

I could provide some details form Profiler if needed. Feel free to request the data you may need for investigation.

p.s. could it be like I do smth wrong? itbh I don't see where I could do anything wrong, but maybe you have an idea...
