ios – Reminiscence administration situation whereas Name Obj-C in Swift

I am presently creating a local plugin for a Capcitor app. I’ve little or no expertise with native iOS growth, Swift and Obj-C.

I exploit a framework (FunSDK) which is written in C++.
I name this in an Goal-C++ wrapper.
As described right here: https://medium.com/@cecilia.humlelu/set-up-c-library-dependencies-in-swift-projects-5dc2ccd2ddaf

The wrapper is then accessible in Swift by way of the bridging header.
This works to this point, I can name the features from the framework and they’re executed appropriately.
Nevertheless, the features of the framework are executed asynchronously. When a result’s obtained, the “OnFunSDKResult” technique is at all times executed.

Throughout this step I get an EXC_BAD_ACCESS error whereas debugging. Then I ticked “Zombie objects” below the diagnostics settings. This causes execution to cease with an EXC_BREAKPOINT.

As I perceive it, after executing the iniXMSDK technique, the FunSDKWrapper class is cleared from reminiscence earlier than executing the “OnFunSDKResult” technique?

I’ve additionally already built-in a completionHandler, which is just known as within the “OnFunSDKResult” technique in order that information is transferred to the Swift class. Nevertheless, that does not assist both.

I don’t know the way to proceed.
I hope someone may help me.

For those who want any extra data, I’d be comfortable to supply it.
