Runtime Error: SIGABRT on fileprivate var connectedDevices = Dictionary<UUID, Peripheral>()

I get this runtime error Runtime Error: SIGABRT on fileprivate var connectedDevices = Dictionary<UUID, Peripheral>() in BleClientManager:

My code is:

class BluetoothList extends Component {
    componentWillMount() {
        this.manager = new BleManager(); // <------ HERE
        this.manager.onStateChange((newState) => {
          console.log("State changed: " + newState)
        })
        console.log('will mount test');
    }

    componentWillUnmount() {
        this.manager.destroy();
        delete this.manager;
    }

    render() {
       ...
    }
}

I am running on my device using Expo as a detached app. My dependencies are:

"dependencies": {
    "expo": "16.0.0",
    "react": "16.0.0-alpha.6",
    "react-native": "https://github.com/expo/react-native/archive/sdk-16.0.0.tar.gz",
    "react-native-ble-plx": "^0.4.0",
    "react-native-elements": "^0.11.2"
  },

Alternatively from root of your project you can execute below commands

cd node_modules/react-native-ble-plx/
./build_ios_frameworks.sh

to force rebuild of native libraries. Let me know if it helped.
