I have a React Native App for which I am trying to build an iOS share extension, using Swift. I'd like the share extension to have access to the token set in the React Native app. I have set up an app group, which contains the app and the share extension.
In the app, I am using react-native-default-preference to set UserDefaults.
import DefaultPreference from 'react-native-default-preference'
DefaultPreference.set('authToken', token)
In my share extension view controller, I have
if let userDefaults = UserDefaults(suiteName: "group.myGroup.myApp") {
let value1 = userDefaults.string(forKey: "authToken")
print("retrieved token value\(value1)")
}
This always prints out nil
. I'm basically new to Swift and Xcode so I have no idea if what I am doing should work. I'm also not certain if I should have the app running in Xcode or the share extension running, so I keep switching back and forth between the two, but it doesn't work either way.
Is there something that I am missing, or can anyone offer an alternative solution? Many thanks in advance!
I needed to call DefaultPreference.setName('group.myGroup.myApp')
in my RN project. Thanks to kevinresol , who developed the library, for the solution.
