After setting up my main application class to use SwizConfig and compiling I was greeted with this error.

“In initializer for ‘mxmlContentFactory’, type org.swizframework.SwizConfig is not assignable to target type Array or target element type mx.core.IVisualElement”

The solution: Flex 4 introduced a new method of grouping non-visual elements together <fx:Declarations>. In Flex 4 non-visual elements such as formatters, validators, effects etc. need to be grouped within a <fx:Declarations> section. So if you’re using Flex 4 (Gumbo) your SwizConfig would look something like this:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication
	xmlns:swiz="http://swiz.swizframework.org"
	xmlns:fx="http://ns.adobe.com/mxml/2009"
	xmlns:s="library://ns.adobe.com/flex/spark"
	xmlns:mx="library://ns.adobe.com/flex/halo">
 
	<fx:Declarations>
		<swiz:SwizConfig 
			viewPackages="com.myapp.views"
			eventPackages="com.myapp.events"
			strict="true"
			beanLoaders="{[Beans]}" />
	</fx:Declarations>
 
</s:WindowedApplication>
