I suggest to add some constraints to the Image View. In Xcode, select the Main.storyboard and drag an Image View to the center of the View Controller. You will need the link of the above image in your iOS app. I will use this image to exemplify uploading an image from our iOS application.įor the download image test, you can use any image from the web, or you can use same image as me. You can use the same image as me, tree.png, if you wish. Just double click on AlamofireExample.xcworkspace and it will open in Xcode.ĭrag an image from your computer to the AlamoFireExample project and be sure to check Copy items if needed. Now, execute the next command in Terminal: 1 pod installįrom now on, you will use AlamofireExample.xcworkspace instead of the usual AlamofireExample.xcodeproj. To (see lines 2 and 9): 1 # Uncomment the next line to define a global platform for your project 2 platform :ios, '10.0' 3 4 target 'AlamofireExample' do 5 # Comment the next line if you're not using Swift and don't want to use dynamic frameworks 6 use_frameworks! 7 8 # Pods for AlamofireExample 9 pod 'Alamofire', '~>4.4' 10 end Now, create a new Podfile and open this in your preferred text editor: 1 pod init 2 open PodfileĬhange the content of the file from: 1 # Uncomment the next line to define a global platform for your project 2 # platform :ios, '9.0' 3 4 target 'AlamofireExample' do 5 # Comment the next line if you're not using Swift and don't want to use dynamic frameworks 6 use_frameworks! 7 8 # Pods for AlamofireExample 9 10 end Assuming you’ve named your project “AlamofireExample” and that you’ve saved it on your Desktop: 1 cd ~/Desktop 2 cd AlamofireExample 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:Ĭlose the Xcode project and, from a Terminal, go to the project folder. Now, you can install CocoaPods: 1 gem install cocoapods ![]() Optionally, if you want to use a more modern Ruby, you can use the Homebrew package manager: 1 /usr/bin/ruby -e "$(curl -fsSL )" 2 brew install rbenv ruby-build 3 echo 'if which rbenv > /dev/null then eval "$(rbenv init -)" fi' > ~/.bash_profile 4 source ~/.bash_profile 5 rbenv install 2.4.1 6 rbenv global 2.4.1Ĭheck if you can use the latest Ruby version with: 1 ruby -v The above command will use the outdated Ruby 2.0 that comes with macOS. Open a Terminal and install CocoaPods: 1 sudo gem install cocoapods I found that the easiest approach to get started with Alamofire for iOS projects is to use CocoaPods. As a side note, macOS comes with an old version of Apache and PHP 5.3 already installed.įirst, you need to install Alamofire. Personally, I use the free version of MAMPP which allows me to easily switch between Apache and NGINX if necessary. If this is not the case, you can use a local Apache or NGINX web server. 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. ![]() 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. This is a short tutorial about uploading and downloading images with Alamofire from an iOS, Swift 3, application. Verify whether an error was received or not before getting a valid image from the data.Solarian Programmer My programming ramblings Home Archives Contact Privacy Swift Alamofire tutorial uploading and downloading images Posted on by Paul Handler gives you data, response, and error. Once the request is completed, the completion In the above example, you can see that validating the URL object before proceeding further is always a viable option. Import UIKit let url = URL (string : "url_string" ) ! let task = URLSession.
