Bluetooth technology has become an integral part of modern mobile applications, enabling seamless wireless communication between devices. Whether it’s for connecting to a wireless headset, transferring files, or interacting with smart home devices, Bluetooth plays a crucial role in enhancing user experience.

For mobile developers, understanding how to implement Bluetooth functionality is essential. In this post, we’ll dive into a detailed comparison of the Bluetooth development frameworks for iOS and Android.

Nowadays, users demand quick and easy access to services they need, without downloading the full version of an app. App Clips - a feature introduced by Apple on iOS 14 - offers a solution to this demand by enabling users to access a small part of an app. By integrating your Bluetooth-enabled app to App clip, you can take user experience to the next level. This opens up new possibilities, such as allowing users to connect to nearby devices, perform a specific feature, and more. In this tutorial, I’ll guide you through integrating Bluetooth into your App Clip. Whether you’re a seasoned developer or a newbie, you will find everything you need to get started. So, let’s dive in!

In the ever-evolving world of mobile app development, keeping users engaged and informed is key. For iOS developers, background notifications are a powerful tool that enhances user experience without interrupting their current activities. But what exactly are background notifications, and how do they work? Let’s dive into the details.

Push notification allows your app to reach users more frequently, and can also perform some tasks. In this tutorial, we will learn how to config apps to get remote notifications, display contents and then perform some actions when the user presses in.
Let’s get started.

iOS developers are building applications that play both roles Peripheral and Central to exchange data with other copies apps. The data can be exchange a small of information via BLE packets or the signal strength indicator (RSSI) value from one to the others. However, keeping the app last forever in the foreground is impossible. Sooner or later, the app will enter to background mode by the user and finally will be suspended by the system depending on RAM available, power consumption and other factors. Thus, understanding the procedure of advertising and scanning on iOS devices helps you to build good applications that fit your expectations.
At the end of this tutorial, we will build a simple application that acts as both a scanner and an advertiser. When two applications find each other, they will write a log record for analysis. Depending on the results, we will find out how effective our application is using Core Bluetooth.
Let’s switch the gear!

As your iOS development skill is growing, I believe you use UIScrollView, UICollectionView, UITableView, and other native views regularly and proficiently in your applications. Yet, some iOS developers still don’t know what exactly UIStackView is, what it uses for or in which situation should we use UIStackView.
In this tutorial, I will introduce you to UIStackView - A view helps us to simplify our iOS layouts.

Let’s imagine you’re going to build an application that allows the user to add or remove views in run time. Remember how we will accomplish this task? We first have to remove all constraints in the relative area and update them all over again. Or remember the case where you implement the sign-in / sign-up view, you add many text fields and manually set constraints between those views. In such situations, UIStackView appears to be more useful than other views.

In the previous post, Advanced iOS Concurrency: Operations, we walked through the Operation concepts on iOS and made a demo application that fetches some posts of mine. After downloading the cover images, they will be applied to a simple filter, then be displayed in a table view. The application, however, has not been completed yet. There’s something that went wrong with our app making the app did not show downloaded images properly. In this tutorial, we will continue where we left off.
Get ready!

There are two techniques to deal with Concurrency in iOS: GCD - Grand Central Dispatch and Operations. Most of the time, GCD provides most of the concurrency capabilities you need. Yet, sometimes you’ll want some extra advanced customizations. It’s time to use Operations. This tutorial will introduce Operations in Swift, also explain when and why we use Operation instead of GCD.
Let’s switch the gears!

There is a big gap between knowing the path and walking through the path.

Some applications can survive without any data storage. Most other useful applications, however, save some state such as user configurations, user profile, goals, etc. on iOS, Apple provides Core Data as a framework to persist your valuable data. One thing to keep in mind that although CoreData can store data in a relational database it’s actually not a database engine.
In this tutorial, I will share with you a bad experience I faced when I work with Core Data. Hopefully, after reading my sharing, you will avoid facing the same problem in your projects.
Let’s get started.

Last night, I read a chapter of a book as one of my favorite books: "The pragmatic programmer" (By Andrew Hunt and David Thomas). This chapter discusses how to use assertion to make the code easier for debugging. We all know that assertion is an essential tool for writing tests, but It does more than that. Let’s go with me to meet this guy: Assertion.
