Unnecessary code clean up

MyTest.swift

class MyTest: NSObject {
	private var identifier = "myIdentifier"

	var defaultContent: [String]

	init(withItem item: String) {
		defaultContent = [item]
	}

	class func fetchInfo(success: (info: [AnyObject: AnyObject]?) -> (), failure: ((error: NSError?) -> ())? ) {
        APIClient.fetchInfoWithSucess({ (_, _, json) -> Void in
            info = json as? [AnyObject: AnyObject])
            
            success?(info: info)
            }, failure: { (_, _, error) -> Void in
                failure?(error: error)
        })
    }
}
