I've been attempting to debug this for a couple hours today. Something looks amiss with how there is a javascript implementation of the ios plugin alongside the ios sub package and swift implementation. I'm referring to this: https://github.com/ionic-team/capacitor-plugins/blob/main/text-zoom/src/index.ts#L6

Update
I changed that line to be the web implementation, and it's working on iOS now.

On web, this line appears to create an infinite loop which is causing the hangup: https://github.com/ionic-team/capacitor-plugins/blob/main/text-zoom/src/ios.ts#L21

It seems like the iOS plugin is unfinished too, missing get and set implementations. Maybe I'm missing the inheritance chain thought.

See my PR (#338) for progress. I think I've found most of the problems that would take this plugin to a functional state on iOS, but I've taken it about as far as I know how.
