ios - Alamofire 上传仅在 iphone 6s plus 上崩溃

我的应用使用 alamofire 4.0.1 在除 iphone 6s plus 之外的所有设备上完美上传照片。(在 iphone 4s、5、5s、6、7、7plus 版本 9.2 和 10.1 上测试)

        let image = profileimage
        Alamofire.upload( multipartFormData: { multipartFormData in
                // import image to request
                if let imageData = UIImageJPEGRepresentation(image!, 1) {

                    multipartFormData.append(imageData, withName: "user_profile.profile_picture", fileName: "profile_picture"+NSUUID().uuidString, mimeType: "image/png")
                }      
            },
            usingThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold,
            to:  baseURL+String(currentUser.id)+"/",
            method: .put,
            headers: headers,
            encodingCompletion: { encodingResult in
                switch encodingResult {
                case .success(let upload, _, _):
                    upload.responseJSON { response in
                        let user = createUserFromJSON(response.result.value as! NSDictionary) //crashes here, response is nil
                        completion(user, nil)
                    }
                case .failure(let encodingError):
                    let error = encodingError
                    completion(nil, error)
                }
        })

在 iphone 6s plus 上它崩溃了:

这与 Alamofire 无关!具有最大文件上传大小的是 NGINX。我是通过打印 responseString 而不是 JSON 发现的。它说“请求实体太大”。

          upload.responseString { response in
             print(response.result.value)
            }
