React Native error: Element type is invalid: expected a string or a class/function but got: object
<p>I am getting this error and I am having a lot of trouble fixing this.</p>

<p>What I am trying to do here is have 3 different screens and have a tabbar that navigates to each screen.</p>

<p>Here is my index:</p>

<pre><code>import React, { Component } from 'react';
import { AppRegistry, Navigator, StyleSheet, View, Text } from 'react-native';

import Nav from './app/components/Nav';
import Screen from './app/Screen';

import Tabs from 'react-native-tabs'

import SwitchView from './SwitchView';

class Proj extends Component {

constructor(props){
    super(props);
}

render(){
    var x = "FeedView";
    return(

          &lt;View style={styles.container}&gt;
            &lt;Tabs selected={x} style={{backgroundColor:'white'}}
                  selectedStyle={{color:'red'}} onSelect={el=&gt; {x = el.props.name}}&gt;
                &lt;Text name="FeedView"&gt;First&lt;/Text&gt;
                &lt;Text name="WikiView" selectedIconStyle={{borderTopWidth:2,borderTopColor:'red'}}&gt;Second&lt;/Text&gt;
                &lt;Text name="BoardView"&gt;Third&lt;/Text&gt;
            &lt;/Tabs&gt;

            &lt;SwitchView id={x}/&gt;

          &lt;/View&gt;
    );
}
}

const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
})

AppRegistry.registerComponent('Proj', () =&gt; Proj);
</code></pre>

<p>here is my SwitchView:</p>

<pre><code>import Feed from './app/pages/Feed/Feed';
import Board from './app/pages/Board';
import Wiki from './app/pages/Wiki';

class SwitchView extends Component {
render(){
    var { id } = this.props;

    switch (id) {
        case "FeedView":
            return &lt;Feed/&gt;
        case "WikiView":
            return &lt;Wiki/&gt;
        case "BoardView":
            return &lt;Board/&gt;
    }
}
}
</code></pre>
