Why You Should Use the Combine Framework for iOS Development: Simplified Asynchronous Programming, Improved Readability, and More

The Combine framework is a relatively new addition to the iOS development ecosystem, introduced by Apple in 2019. It is a powerful tool for reactive programming and can simplify the way developers handle asynchronous operations and data flow in their applications. In this article, we will explore why you should use the Combine framework for iOS development.

1. Simplified Asynchronous Programming

One of the primary benefits of the Combine framework is its ability to handle asynchronous programming in a simplified way. In traditional iOS development, handling asynchronous operations often involves using callbacks or closures, which can lead to complex and hard-to-read code. With Combine, developers can use operators to handle asynchronous events and data flow, making the code much easier to read and maintain.

2. Improved Code Readability and Maintainability

The Combine framework also offers improved code readability and maintainability. By using declarative code, developers can write more concise and readable code that is easier to understand and debug. This leads to a more maintainable codebase, which can be easily modified and updated as needed.

3. Built-in Error Handling

Another advantage of using the Combine framework is its built-in error handling. With traditional asynchronous programming methods, error handling can be difficult to implement and maintain. Combine provides a set of operators specifically designed for error handling, making it easier for developers to handle errors and keep their code clean and organized.

4. Integration with SwiftUI

Combine was designed to work seamlessly with SwiftUI, Apple’s new declarative UI framework. SwiftUI uses a reactive programming paradigm that aligns well with the reactive programming paradigm of Combine. By using both frameworks together, developers can create powerful and efficient applications with less code and better performance.

5. Greater Flexibility and Control

Finally, the Combine framework offers greater flexibility and control over data flow and event handling. Developers can use operators to define complex data flow patterns, which can be difficult to achieve with traditional programming methods. This allows for greater customization and control over how data is processed and displayed in the application.

In conclusion, the Combine framework offers a range of benefits for iOS developers, including simplified asynchronous programming, improved code readability and maintainability, built-in error handling, integration with SwiftUI, and greater flexibility and control over data flow. By using Combine in your iOS development projects, you can create more efficient, readable, and maintainable code, while also enjoying greater control and flexibility over your data flow and event handling.

How ChatGPT Can Revolutionize iOS Development: 5 Ways It Can Help Improve the Development Process

As a large language model trained by OpenAI, ChatGPT has a wide range of capabilities that can be leveraged to help with iOS development. In this article, we’ll explore some of the ways that ChatGPT can be used to improve the development process and make it easier for developers to build high-quality iOS apps.

  1. Code Completion and Suggestions
    One of the most powerful features of ChatGPT is its ability to provide code completion and suggestions based on the context of the code being written. This can be especially helpful for iOS developers who are working with complex APIs and frameworks, as ChatGPT can provide suggestions for method calls, property names, and more. This not only speeds up the development process, but can also help prevent errors and improve code quality.
  2. Troubleshooting and Debugging Assistance
    ChatGPT can also be used to help troubleshoot and debug iOS apps. For example, developers can describe an issue or error they are experiencing, and ChatGPT can provide suggestions for potential causes and solutions. Additionally, ChatGPT can help with understanding error messages, debugging techniques, and other aspects of the iOS development process.
  3. Code Refactoring and Optimization
    ChatGPT can also be used to help with code refactoring and optimization. For example, developers can describe a piece of code they are working on, and ChatGPT can provide suggestions for ways to simplify or optimize it. This can be especially helpful for identifying performance bottlenecks or reducing the complexity of code, which can improve the overall quality and maintainability of an iOS app.
  4. Learning Resources and Documentation
    ChatGPT can also be used to provide learning resources and documentation for iOS development. For example, developers can ask questions about a particular API or framework, and ChatGPT can provide detailed explanations and examples. Additionally, ChatGPT can provide links to documentation, tutorials, and other resources that can help developers learn and improve their skills.
  5. Natural Language
    Interfaces Finally, ChatGPT can be used to create natural language interfaces for iOS apps. For example, developers can create chatbots or virtual assistants that can interact with users in natural language, providing information or performing actions within the app. This can improve the user experience and make it easier for users to interact with the app.

In conclusion, ChatGPT has a wide range of capabilities that can be leveraged to improve the iOS development process. From code completion and suggestions, to troubleshooting and debugging assistance, to code refactoring and optimization, to learning resources and documentation, to natural language interfaces, ChatGPT can help iOS developers build high-quality apps more quickly and efficiently.

What happened at WWDC22?

Finally, iOS 16 and SwiftUI 4 are out! As an iOS Developer, this was the most exciting WWDC for me compared with previous events. We know that when Apple released Swift 4.0 it was the most stable version of Swift. This common opinion is also valid for SwiftUI.
So, let’s start with iOS quickly:

  1. Notifications
    The placement of notifications changed. It will be at the bottom of the screen. Plus, you can hide them.

2. Widgets
Widgets are also available on the lock screen. I think this is preparation for ‘Always on Display’ iPhones.

3. Mail
Now, Mail using your Focus status to show important mails in the current time. Also, you can undo or reschedule your email.

4. iMessage
iMessage updated. You can editunsent, and unread your messages! (finally right!?) Moreover, it is more interactive in group chats. But, I was expecting more than these features like replying with swipe gestures or creating broadcast messages.

5. Live Text
I know, I know. It is already available on iOS 15 but now, you can copy texts from video either. Pause, select, and copy!

6. CarPlay (late 2023)
And one of the most important news is CarPlay. These days all cars evolving into electric cars. Because of this, car makers adding more screens. Apple taking this opportunity to the next level. You can even customize your speedometer.

More details: https://www.apple.com/ios/ios-16-preview/

What does it mean for Owners (Project managers, Start-up founders, Product owners, etc.)

1- Focus Filters
The first thing that I will mention is Focus Mode. We are already familiar with this feature. Sleep, Work, Personal, Fitness, etc. With these modes, you can customize your app. iMessage was already using this feature to notify other users.

Focus mode on iMessage

You can customize your notifications based on users’ Focus Mode. Let’s say, you have a news application. Do you want to send notifications to users while they are doing Fitness or Sleeping? Or maybe you want to send notifications while they are working.

2- On-Screen Widgets
Widgets are not a new thing in iOS but On-Screen is making difference. You can inform your users on the lock screen. Apple already informs users with Fitness, Alarm, Stocks, Calendar, etc apps. But there is a limitation. Users could add 4 small widgets or 1 big and 2 small widgets. Because of that, you have to be sure that users are willing to add your app’s widgets.

3- Live Activities
I think this is the most important feature for us. Apple already gives an example of how to use this feature on the lock screen. You can stream your app’s data to users without any crowd of notifications. Other examples?

Think of yourself as the owner of a VPN application. You can stream upload and download info to the user.
Or you could have a cryptocurrency application. Your app could inform cryptocurrencies.

4- Shared with You
As a fan of iMessage, I love to see ‘Shared with You’ info while I am looking at photos in the Photos app. Now, you can develop your own shared with your feature.

Shared with You

If you have an app for making makeup or have some editing functionality on the photo this feature could save time for your users.

5- RoomPlan
Apple has Lidar on iPhone 13 series. It could detect objects in a 3D way. With RoomPlan your app could map users’ houses, offices, and other environments.


You could have a smart vacuum device application and your smart vacuum wants to know which areas are suitable for vacuuming.

Or you could have a plant application and with RoomPlan you could suggest a new placement of plants.

6- Weather
You don’t have to use 3rd party weather APIs to show the current weather temperature anymore. Apple provides a new kit for this feature. It’s a lifesaver, right!?


For Developers

First of all, let’s start with Recap videos. Are there any developers who didn’t watch these videos?! Now, it’s a good time to give break from reading and watch these videos.

Day 1: https://www.youtube.com/watch?v=m0Yb-QZ6zD8
Day 2: https://www.youtube.com/watch?v=TEblbkq8Qnc
Day 3: https://www.youtube.com/watch?v=KqkZJ7di8jc

Day 5: https://www.youtube.com/watch?v=PMCDIIxBiZA

1- NavigationStack
Isn’t that your favorite improvement in SwiftUI? We have been waiting for 3 years to use this feature. After SwiftUI 4, we don’t have to make any excuses to the product team about how SwiftUI makes it hard to navigate to other screens. 😅

2- BottomSheets
Remember, how many times you imagined having Apple’s native bottom sheet? Now, dreams come true. It has two options which are .medium and .large. Also, it is resizing itself. No, I am not crying. 🥲

3- onTapGesture [Location Detection]
Let’s say, you have one view and want to detect the user’s tapping location exactly. In the beginning, you may confuse, and even say yourself to “Why would I use this feature?”. But don’t rush, give yourself some time. Sometimes it could be a great and simple solution to your complex issues.

4- ShareLink & RequestReview
It is time to remove all junky UIActivityViewController code or custom Share Sheets. (Not now, after you change your app’s min. deployment to iOS 16). One line code will save your and your teammate’s time. This is also one of the time saver features of SwiftUI. Just with one line (yes, one line), you could ask for a review from your users.

5- TextAnimation
This is one of mine -where do I use this thing- feature. 😅 Maybe you could use this feature in one of your applications that has chat options (like Whatsapp, Tinder, etc.).

Last but not least, don’t forget to watch these videos to keep yourself updated!

One more thing…

M2 Apple Silicon chips have arrived. For now, it is available on MacBook Air but we know definitely that it will be in MacBook Pro, Mac Pro, Mac mini, etc. too.

While I was preparing this article, a 13″ MacBook Pro M2 was on the presale. 😅


I am dropping playlists here for coders, programmers, or software engineers (depends on how you call yourself) that are just released by Apple.
