Additional context Defining the scheme in the <ShareIntentProvider> seems to fix the issue while using the iOS simulator. Though the issue persists on a physical iOS device? No clue how this happens, but it does.

<ShareIntentProvider
            options={{
                debug: true,
                scheme: "<scheme here>",
                onResetShareIntent: () => {
                    // ...
                }
            }}
        >

According to one of the crash reports, it looks like the issue might be getting caused here, though I'm unsure how to resolve it permanently. And in a way that solves it on all devices.

I need to add the support for multiple scheme, I didn't know it was possible to do that. added in my TODO

@betabites good catch ! on iOS we need to open the app using the deeplink url : myapp://, if we have more than one scheme it didn't know which one to use. Getting the first scheme should work properly

app.json :

  "scheme": ["myapp1", "myapp2"]

then inject scheme[0] into ShareExtensionViewController.swift (eg: let shareProtocol = "myapp1")

available in v2.1.0

I need to keep more up-to-date with my GitHub. Amazing! Thank You :)
