[BUG] Compile error in Swift code

[mdhaney]

Bug

I have read the Troubleshooting page: Yes

Describe the bug
I'm trying to use the library in an Expo project using their EAS build tool (which lets you add third party native modules) and I get the following error while compiling the pod:

Any idea why I could be getting this error? Do I need to be compiling against a certain version of the iOS APIs or something like that? Thanks for any help, because I really need to get this working.

oh, interesting. Does everything work smoothly if you add an override keyword to that function?

[mdhaney]

Thanks for the quick response! I thought of trying what you suggested, but unfortunately there's no easy way for me to make that change. Since I have to use Expo's EAS build, which is a cloud service, the only way I can add modules is through NPM. So for me to test that, I would have to clone, make the change, and publish a private NPM module which I'm not really setup to do.

How hard would it be for you to publish a version with this fix so I can test it? Also, I looked in the logs and noticed it was using version 15 of the the iOS SDK, and version 5.4 of Swift. So maybe you could try a build beforehand using those versions and confirm if you can reproduce the error and if adding the override keyword fixes the problem.

I ran into this same issue, and was able to hack together a fix by updating the override keyword and proxying NPM locally with verdaccio

Same error. Unable to build.

Any progress on this? More info:

@mdhaney Hi, I know that the thread is not very recent, but since I'm trying to implement this package on expo I wonder if you could kindly share the code of the plugin you used.
At the moment I can't even get the library to work on android. In fact, I get the error "Plugin with id 'maven' not found".
Thank you.
