We will use a delegate to detect when the user has finished the selection process, and obtain the selected image. We can, for example, create a button that when clicked will open the UIImagePickerController like this:.
Notice the line myPickerController. The function above will be called when the user has selected and image. We will use it to recover the image selected by the user:. If we try to run the code above as it is, the application will crash. If we examine the console we will see the following error message:. This app has crashed because it attempted to access privacy-sensitive data without a usage description. Notice that the above description will be displayed to the user the first time he access the functionality:.
If you want to read more about purpose strings you can check this wonderful post at useyourloaf. So we can send it to the server via REST, as we would do with any other kind of data. We might do it using a plain URLRequest or using a networking library like Alamofireand as content-type we are going to use multipart data.
The content type multipart is used when we want to send mixed type of data; a typical example would be an email where we can send text, and images or files as attachments. And that is what we do in the following lines:. Now that we have recovered the image selected by the user, and we have encoded as a base64 string we can send it to the server in a JSON following the structure described above remember to configure ATP if you are sending your data over httpinstead of using https.

Quick and Dirty Guide to How to December 6, at pm. It is a good solution to have a little more control in the transfer of files, the problem is in the increase of bytes, for example:.This is a short tutorial about uploading and downloading images with Alamofire from an iOS, Swift 3, application. I assume that you have the latest Xcode installed on your Mac, and that you know how to code small iOS applications in Swift 3.
I also assume that you have access to a server, ideally you have your own server with a domain name and a SSL certificate installed. First, you need to install Alamofire. I found that the easiest approach to get started with Alamofire for iOS projects is to use CocoaPods.
Open a Terminal and install CocoaPods :. Optionally, if you want to use a more modern Rubyyou can use the Homebrew package manager:. Once you have CocoPods installed, open Xcode and create a new project, select Single View Application and be sure to select Swift in the language drop down list:. Close the Xcode project and, from a Terminal, go to the project folder.
From now on, you will use AlamofireExample. Just double click on AlamofireExample. Drag an image from your computer to the AlamoFireExample project and be sure to check Copy items if needed. You can use the same image as me, tree. I will use this image to exemplify uploading an image from our iOS application.
You will need the link of the above image in your iOS app. In Xcode, select the Main. I suggest to add some constraints to the Image View. First make sure it is aligned horizontally and vertically:. Select the view controller from the Main. This should open ViewController. Leave it just above the viewDidLoad.AWS S3: Uploading Files - Swift 4, Xcode 9
Chose a descriptive name, something like downloadImage and press Connect :. If you see an error, simply build the project, after which Xcode will recognize the Alamofire module.
For simplicity we will use an image bundled with our application, the tree. Usually, no server will let you upload an image without some form of authentication. In order to be able to use this local server, we need to add an exception for our localhost. In Xcode, right click on Info. Copy the next lines just before the last closing dict tag:. Be sure that you have write rights on your target server, otherwise the upload will fail.
Here is the response from the server, the jsonResponse variable from the Swift code, as seen in the output window of Xcode:. Swift Alamofire tutorial uploading and downloading images Posted on May 2, by Paul This is a short tutorial about uploading and downloading images with Alamofire from an iOS, Swift 3, application. Open a Terminal and install CocoaPods : 1 sudo gem install cocoapods The above command will use the outdated Ruby 2.
Now, execute the next command in Terminal: 1 pod install From now on, you will use AlamofireExample. Chose a descriptive name, something like downloadImage and press Connect : Import the Alamofire module in ViewController.Use the Download Materials button at the top or bottom of this tutorial to download the starter project. The app for this Alamofire tutorial is named PhotoTagger. This service will perform some image recognition tasks to come up with a list of tags and primary colors for the image:.
Note: To learn more about CocoaPods, check out this tutorial by Joshua Greene, published right here on the site. Click Select Photo and choose a photo. The background image will be replaced with the image you chose. Open Main. All that remains is to upload the image and fetch the tags and colors. Imagga is an image recognition Platform-as-a-Service that provides image tagging APIs for developers and businesses to build scalable, image-intensive cloud apps.
You can play around with a demo of their auto-tagging service here. Imagga requires an authorization header in each HTTP request so only people with an account can use their services. After you create your account, check out the dashboard:. Note: Make sure you copy the whole secret token, be sure to scroll over to the right and verify you copied everything.
HTTP is the application protocol, or set of rules, web sites use to transfer data from the web server to your screen. HTTP defines several request methods, or verbs, the client your web browser or app use to indicate the desired action:.
REST has several architecture rules that enforce things such as not persisting states across requests, making requests cacheable, and providing uniform interfaces. This makes it easy for app developers like you to integrate the API into your app, without needing to track the state of data across requests.
It provides a straightforward, human-readable and portable mechanism for transporting data between two systems. In addition, there are numerous third party libraries that help with handling JSON. Trying to understand how every little piece works can be overwhelming. Libraries like Alamofire can help reduce the complexity of working with these services, and get you up and running faster than you could without their help.
Why do you need Alamofire at all? The short answer is Alamofire is based on URLSessionbut it frees you from writing boilerplate code which makes writing networking code much easier. You can access data on the Internet with very little effort, and your code will be much cleaner and easier to read.
You deserialize the response with responseJSON options:completionHandler: and calling validate to verify the response status code is in the default acceptable range between and simplifies error condition handling. Open ViewController. Next, find upload image:progressCompletion:completion: at the bottom of the file.
It is currently only a method stub, so give it the following implementation:.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. In order to keep Alamofire focused specifically on core networking implementations, additional component libraries have been created by the Alamofire Software Foundation to bring additional functionality to the Alamofire ecosystem.
CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website.
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate Alamofire into your Xcode project using Carthage, specify it in your Cartfile :. The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but Alamofire does support its use on supported platforms.
Once you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the dependencies value of your Package. If you prefer not to use any of the aforementioned dependency managers, you can integrate Alamofire into your project manually. Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:.
Add Alamofire as a git submodule by running the following command:. Open the new Alamofire folder, and drag the Alamofire. It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter. Select the Alamofire. Next, select your application project in the Project Navigator blue project icon to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.
You will see two different Alamofire. It does not matter which Products folder you choose from, but it does matter whether you choose the top or bottom Alamofire. You can verify which one you selected by inspecting the build log for your project. The Alamofire. The following radars have been resolved over time after being filed against the Alamofire project. Alamofire is named after the Alamo Fire flowera hybrid variant of the Bluebonnet, the official state flower of Texas.
Alamofire is owned and maintained by the Alamofire Software Foundation. You can follow them on Twitter at AlamofireSF for project updates and releases. If you believe you have identified a security vulnerability with Alamofire, you should report it as soon as possible via email to security alamofire.
Please do not post it to a public issue tracker. The ASF is looking to raise money to officially stay registered as a federal non-profit organization. Registering will allow us members to gain some legal protections and also allow us to put donations to use, tax-free.

SessionManager configuration: configuration. I've got it working now. For me, turns out it was something pretty stupid, but perhaps it will help someone here anyway:.
In Swift 2. In Swift 3 however URL. Since all Alamofire functions take an URL as argument this is mostly not a problem, but for this scenario it is, since it takes a string. Not working for me.
Does is working for you LucidityDesign? Few global variables in there but you get the point i guess.
Alamofire Tutorial: Getting Started
BilalReffas OK. Perhaps something to do with the parameter encoding you can add as a variable to the normal Alamofire. Have you tried JSONenconding your parameter values inside the for loop as a first line, so before the. Just a hunch as I didn't need to do this myself. If not, can you show us the code where you declare your params?
You should not use this for creating the data representation: String describing: value. The problem with that is, that it's just printing a debug representation of the object and transforms that String to Data. I would suggest introducing a serializer which gives you an appropriate data representation like this:.
You could then check if the data could be serialised and if, set it in the request parameters. I am really excited, if that fixes your problem :.
Thank you everyone for helping each other out here. In the future I'd suggest moving this type of question to Stack Overflow. I'm going to go ahead and close it out for now since there's no actionable Alamofire issue here. I'm done with this, the issue is not in this line multipartFormData. Skip to content.
