Ternary Platform Check Gone Wrong

Spot why the iOS banner shows on every platform.

Codejavascript
import { Platform, View } from 'react-native';

function Banner() {
  return (
    <View>
      {(Platform.OS = 'ios') ? <IOSBanner /> : <AndroidBanner />}
    </View>
  );
}

The Android banner never appears, even on Android. What is the bug?
