Keychain react-native shared with Swift today widget

Question

We have a react-native application that uses react-native-keychain library in this way (like in this issue):

import * as Keychain from 'react-native-keychain';
 try {
            Keychain.setInternetCredentials(
                'device-id',
                'RANDOMDATA',
                DeviceInfo.getUniqueID().toString(),
                { accessGroup: 'org.reactjs.native.example.myreactapp'})
                .then(() => console.log('Done'))
        } catch (err) {
            console.log("error save", err)
        }

I would like to be able to retrieve this data in my today widget made in swift, I would need to know the storage key for that. Below is the way I'm supposed to get it back on the widget:

let itemKey = "device-id"
let keychainAccessGroupName = "3P********.org.reactjs.native.example.myreactapp"

let queryLoad: [String: AnyObject] = [
      kSecClass as String: kSecClassGenericPassword,
      kSecAttrAccount as String: itemKey as AnyObject,
      kSecReturnData as String: kCFBooleanTrue,
      kSecMatchLimit as String: kSecMatchLimitOne,
      kSecAttrAccessGroup as String: keychainAccessGroupName as AnyObject
    ]

    var result: AnyObject?

    let resultCodeLoad = withUnsafeMutablePointer(to: &result) {
      SecItemCopyMatching(queryLoad as CFDictionary, UnsafeMutablePointer($0))
    }

    if resultCodeLoad == noErr {
      if let result = result as? Data,
        let keyValue = NSString(data: result,
                                encoding: String.Encoding.utf8.rawValue) as String? {

        // Found successfully
        print("device-id : ", keyValue)
      }
    } else {
      print("Error loading from Keychain: \(resultCodeLoad)")
    }

The code below come from this blog

But it doesn't work. As you may have noticed I need to pass the device-id to the widget because unlike Android the UUID often changes and we get a different ID on each part which prevents the widget from working properly

Are you able to retrieve `device-id` on the javascript side, after you have set it in the keychain? Perhaps this could help with retrieving your code on the swift side https://stackoverflow.com/a/37539998/5508175 — Andrew, Dec 03 '18 at 22:24

Change this code in APP：

{ accessGroup: 'org.reactjs.native.example.myreactapp'})

to

{ accessGroup: '3P********.org.reactjs.native.example.myreactapp'})
