Description

When using ES6 in Hyperloop methods, e.g. 
    var ButtonDelegate = Hyperloop.defineClass('ButtonDelegate', 'NSObject');

    ButtonDelegate.addMethod({
        selector: 'buttonPressed:',
        instance: true,
        arguments: ['UIButton'],
        callback: (sender) => { 
//                         ^-- Here is the issue
        }
    });
the build fails: 
[ERROR] An error occurred during build after 33s 538ms
[ERROR] not sure what to do with this node (/Users/hknoechel/Documents/Apps/hyperloop-examples/Resources/iphone/alloy/controllers/button.js:58:13)
The error is happening [here](https://github.com/appcelerator/hyperloop.next/blob/master/packages/hyperloop-ios-metabase/lib/generate/custom.js#L773) and looks like the arrow function cannot be mapped to the FunctionExpression and falls through.
