Dealing with memory leak with plugins

I have been working on Ionic for a while now, but I don’t know much about Objective-C. Currently I am trying to diet down my codes, and what I found are a few memory leaks and a few what I believe to be memory bloat. Back onto leaks, they are being pointed out to me by Xcode and they are appeared under keyboards, orientation and email plugins. What should I do here? I don’t want to touch anything that is seemed beyond my scope, but at the same time it affects my app and I can’t just ignore these problems.

Any advice to where i should start and what I should do here?

Thank you
