Shortcode Plugins Giving NSXMLParserErrorDomain error 111

I made a very simple shortcode plugin to display a vimeo video on a post and nothing I seem to do makes it work with the iOS wordpress app.

The shortcode works fine on browsers when you view it, even mobiles, but if I try to view my posts on the iOS wordpress app it gives that same error.

I have also used other shortcode apps and get the same error, such as “Shortcodes Ultimate”.

Is this a known bug for the iOS app? Any workarounds?

Code:

class AEshortcodes {
    // [embedvimeo id="xxx" width="xxx" height="xxx"]
    public static function embedvimeo_func( $atts ) {
        $a = shortcode_atts( array(
            'id' => '00000000',
            'width' => '500',
            'height' => '281'
        ), $atts );

        return '<iframe src="https://player.vimeo.com/video/' . $a["id"] . '" width="' . $a["width"] . '" height="' . $a["height"] . '" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>';
    }
}
add_shortcode( 'embedvimeo', array( 'AEshortcodes','embedvimeo_func' ));
?>

The debug log is not helpful at all, as it just reports the error message:
