Wrapping other asynchronous stuff in promises works like this:
func myThingy() -> Promise<AnyObject> {
return Promise{ fulfill, reject in
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"]).response { (_, _, data, error) in
if error == nil {
fulfill(data)
} else {
reject(error)
}
}
}
}
