iOS crash -> Fatal error: Unexpectedly found nil while unwrapping an Optional value

Sharing image to app in iOS while app is working crashes with error:

    receive_sharing_intent/SwiftReceiveSharingIntentPlugin.swift:192: Fatal error: Unexpectedly found nil while unwrapping an Optional value

I believe some value is expected but `nil` is being received. Can you please have a look, @KasemJaffer ?
