In software development, one of the challenges is software localization. You have to keep the code readable, simple, and understandable as well as providing a better experience for the user. I am not gonna deep dive into this topic.

In the native iOS applications we develop, the localized text management…

We were already familiar with the @ “at sign” in Objective-C. Then we were using @IBAction, @NSCopying, @UIApplicationMain examples in Swift language, and we thought it would be limited to these.

As time passed, Swift began to increase the use of @ prefixed attribute.

By way of the SwiftUI announcement…

Apple almost every year releases a main version of Xcode. And this version of Xcode comes up with several features and improvements.

I’m going to write about source editor improvements in Xcode 13. There is no need to prolong this, you have already heard it from somewhere. I’ll start short.

As you know, Apple has introduced a biometric authentication system TouchID in iOS 7 and iPhone 5S.

The authentication system allows users to unlock the device, and make the purchases in the AppStore/iTunes/others.

In iOS 8, Apple has allowed developers to use the fingerprint sensor authentication mechanism in their applications…

Make some work easier by higher-order functions.

I share programming guides that make programmer’s practices simple.

In this guide, I’m going to explain Swift’s higher-order functions with examples as much as I can.

Sometimes it’s hard to understand what you’re doing with these. …

In some cases, we need the negative of any conditions. At this point, if I describe that case as a basic instance;

if #available(iOS 13, *) {} else {
   someOldStuff()
}

In this specific case, we don’t want that. The positive case is unnecessary and impairs code readability.

Swift’s new feature: Unavailability Condition

if #unavailable(iOS 13, *) {
   someOldStuff()
}

Take a look at the negative availability.

Images that are not used in our projects can sometimes be annoying. One of the biggest results of this is that it increases the size of the application.

On the contrary, when we remove unused images or if they are left, the project is reduced and the application size decreases…

In this iOS guide, I am going to explain collection types that are Arrays and Sets and I am going to reinforce them with short examples.

1. Array
2. Set

Arrays and Sets have several features in common. They both store a collection of values of the same type. …
