Promise.onSuccess立即致電

Question

我使用BrightFutures，當我運行以下代碼時，在geoCoder completionHandler完成之前調用sequence().onComplete和sequence().onSuccess。你能幫我解決這個問題嗎？

self.uploadContentSequence = [Future<Future<Void, NoError>, NoError>](); 

for post in posts { 
    self.uploadContentSequence.append(future(self.preparePostUpload(post))) 
} 

self.uploadContentSequence.sequence().onComplete { (_) -> Void in 
    print("onComplete") 
}.onSuccess { (_) -> Void in 
    print("onSuccess") 
}.onFailure { (_) -> Void in 
    print("onFailure") 
} 

[...] 

func preparePostUpload(post: Post) -> Future<Void, NoError> { 
    let promise = Promise<Void, NoError>() 

    [...] 

    let postLocation = CLLocation(latitude: Double(post.lat!), longitude: Double(post.lng!)) 
    let geocoder = CLGeocoder(); 
    let countryCode = NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String 
    post.country = countryCode 
    geocoder.reverseGeocodeLocation(postLocation, completionHandler: { (placemarks, locError) -> Void in 
     [...] 
     promise.success() 
    }); 

    return promise.future 
}
