I'mfollowing the instructions for setting the position of an ActionItem in the ActionBar for iOS. But when I includeios.position="right" in the ActionItem tag, the Android app crashes when I attempt to load that page. Here's the ActionBar code:

    <ActionBar>      <NavigationButton visibility="collapsed" />      <Label text="My Classes" />      <ActionItem :text="signedIn ? 'Sign Out' : 'Sign In'" ios.position="right" @tap="signInOut" />    </ActionBar>

Any suggestions?
