Tips for update CocoaPods and your project libraries

CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects.

CocoaPods is built with Ruby and is installable with the default Ruby available on OS X. We recommend you use the default ruby.

Update your system

Update your system by following command in terminal.

Above command will install/update rubygems.

Install CocoaPods

Install CocoaPods in your system by following command in terminal.

If you are getting errors above command then use following command.

Check CocoaPods Version

Update CocoaPods Repository

We have to update CocoaPods repository with latest pod updates by developers. Use following command to update CocoaPods repository:

It will take some time to update all sub repositories.

Update pod for your project

If you directly apply the command pod install then some time new pods will not be updated in your project. For that you have to remove that specific pod information from the pod file and you have to apply pod install command. It will remove pod from the project. After that again you have to add the pod information in the pod file. Again you have to apply pod install command to install new version of pod.

Follow the next steps:

1. Remove SomePod from the Podfile

2. Run pod install

pods will now remove SomePod from our project and from the Podfile.lock file.

3. Put back SomePod into the Podfile

4. Run pod install again

This time the latest version of our pod will be installed and saved in the Podfile.lock.

You can update single pod file as follows:

Remove all CocoaPods from a project

Install CocoaPods deintegrate and clean commands from terminal.

Now you have to apply both command to remove all CocoaPods from your project:

How to use Alamofire with Codable in Swift?

Hello after long time I am writing this blog regarding use of Alamofire with Codable model object for the ease of MVC architecture.

Let’s rewind with some of the post which is used to cover this point:

  1. How to use Alamofire and SwiftyJSON with Swift?
  2. How to create a wrapper for Alamofire and SwiftyJSON?
  3. Use of Codable and Coding Key with JSONEncoder and JSONDecoder in Swift 4

Let see about use of Alamofire with Codable model object

Step 1 – Create Codable object based on JSON response.

Here I am taking an example of a web service which contains JSON related to the contact.

So, we can create two Codable files from this JSON as per hierarchy. These would be like as follows:

As you can see we have created 2 objects Contact and Phone. Here Phone is in sub hierarchy.

Step 2 – Let’s update AFWrapper

As we have previously revised blogs, there is a blog mentioned about to create a wrapper of the Alamofire and SwiftyJSON. We have to replace the SwiftyJSON code to return normal dictionary objects, and after that we will convert that dictionary to the Codable object.

So here I have updated the AFWrapper class file to do that thing:

Step 3 – Implement and convert the response in object

We will call a web service which contain that kind of JSON response. And after calling the web-service we will decode the object to create the Codable object.

In above sample I have added one text view in the view controller and I am fetching the data from the contacts API. After that using JSONSerialization and JSONDecoder we will get our decoded Contact object with Phone object.

Conclusion

Swift 4 comes with so many updates. We are going to have a great time exploring them all and finding out so much more by using it on further projects. We have learned about Codable and use of it. You too should go check it out and share your experiences with us in the comments section.

Hope you liked the article.

Happy Coding 🙂
