React Native Facebook login button crashes app in iOS Simulator

I am trying to set up Facebook login in my React Native iOS app using FBSDK. The button renders but when clicked crashes the app in the iOS simulator. It doesn't even console log any errors in the remote debugger.

I added the FBSDKCoreKit.framework and FBSDKLoginKit.framework to my project in xcode and followed this guide on how to modify my info.plist and AppDelegate.m

Is there something wrong with my code for the button?

import React, { Component } from 'react'
import { View } from 'react-native'
import FBSDK from 'react-native-fbsdk'
const { LoginButton } = FBSDK    

import styles from '../styles'    

export default class Login extends Component {
  constructor (props) {
    super(props)
    this.onLoginFinished = this.onLoginFinished.bind(this)
  }    

  onLoginFinished (error, result) {
    if (error) {
      console.log(error)
      alert("Login failed with error: " + error);
    } else if (result.isCancelled) {
      alert("Login was cancelled");
    } else {
      alert("Login was successful with permissions: " + result)
    }
  }    

  render () {
    return (
      <View style={styles.container}> 
        <LoginButton
          publishPermissions={["public_profile"]}
          onLoginFinished={this.onLoginFinished}
          onLogoutFinished={() => alert("User logged out")}
        />
      </View>
    )
  }
}

I needed to change publishPermissions to readPermissions

<LoginButton
  readPermissions={["public_profile email"]}
  onLoginFinished={this.loginFinished.bind(this)}
  onLogoutFinished={() => alert("User logged out")}
/>
