What is the difference between Array and NSArray?
Since Array and NSArray are both core constructs in iOS development, we sometimes forget just how different they are. Here are some major differences between the two constructs that you should know about. Array is a struct, therefore it is a value type in Swift. NSArray is an immutable Objective C class, therefore it is a reference type in Swift. Array is a Swift construct, and generic struct, which means that it can be an array of any specific type (Int, String, etc.). [T] is syntactic sugar for Array. NSArray is an Objective-C construct that can hold any Objective-C ...

Read MoreWhat is a Delegate in Swift?
In this article, you will learn about what Delegate is and how it works. What is Delegation? As the name implies, delegation gives control to other objects. To make it happen, the delegate object has to be assigned to control other objects. In iOS apps, the UIApplicaitonDelegate is an example. UIApplicationDelegate allows you to modify iOS behavior, such as receiving push notifications, opening URLs, and launching apps. A delegation pattern ensures the functionality that needs to be delegated is provided. Delegate patterns enable objects to communicate back to their owners decoupled from their code. It is much easier to ...
Read MoreWhat are the common execution iOS Application Lifecycle?
In this article, you will learn about the different execution states of an iOS application. Based on the current state, you can decide what task you want to perform. There are different states that an app might have. The iPhone operating system (iOS) provides us with different five states of an application like the following − Not running Inactive Active Background Suspended An iOS application runs in several states, known as states of the application life cycle. App life cycles are crucial for iOS developers, as they help them understand how their apps behave. The following states are ...
Read MoreHow to write a Multiple-Line Comment in Swift?
In this article, we will discuss Swift's comments, why, and how to use them correctly in Swift. Always keep one thing in mind while writing code i.e. The code must be written for people to read and understand as much as possible. Similarly to the Swift language, comments are very useful for making your code more easily understandable to you and other developers. All the comments in the code are completely ignored by the Swift compiler. There are two types of comments in Swift − Single Line Comments Multiline Comments Single Line Comments Syntax Swift allows us to ...

Read MoreDesigning patterns used during iOS app development
In this tutorial, you will get to know about some common design patterns that you should follow while making iOS apps. What are Swift Design Patterns? In Swift, design patterns make the development process easy for developers. A productive and effective work environment can be created by following the design patterns. An iOS design pattern is a set of repeatable methods for creating apps. What are the most common design patterns used in iOS development? Builder Facade MVC Singleton Viper MVVM Adaptor Observer Factory Method Let's talk about some of them to understand how they work − Algorithm ...
