You may have seen the Mac, iPad, Apple Watch, and other various devices if you have been following Apple products for a while or have an interest in the tech industry. However, if not, that is okay, maybe you are more of an Android OS person. At the end of the day, Apple or Windows all operate on an operating system, i.e., OS. 

Moreover, these devices are utilized in apps with Swift UI for iOS App Development. The apps are created with a programming language designed for each platform. Devices have multiple apps and utilities, which are developed with a programming language. 

Most of the Android apps are created using Java or Kotlin. In contrast, Apple-product apps are coded in distinct languages. This includes C# and swift UI, which is utilized by developers for iOS app development.  

Swift is one of the most popular and ideal for iOS app developers worldwide to develop high-performance and strong apps. It has all the necessary capabilities to create a reliable and powerful user interface for an app. 

Are you a prospective iOS app designer or a novice in iOS programming and want to explore Apple products? If you said YES, then this blog post is right for you.

Latest Features of Swift 5.0 for iOS App Development

Latest Features of Swift 5.0 for iOS App Development

The current version, i.e., Swift 5.0 is the latest one for macOS and iOS. Needless to say, all existing versions are becoming better than the previous ones as they contain some upgrades.  

An iOS app developer should know the following new features of Swift 5 since 2014 and that its community base is upgraded to 600 contributors.  

However, it is possible to consider objective C to develop an iOS app, but open source makes it fit to do the job with diverse OS systems. Another thing that makes it fit is that it can manage the backed capabilities as well. 

Exclusive Package Manager  

The amount of personal touch introduced to the latest release opens many marvels to improve the iOS app development. This includes customizable deployment targets, advanced build settings, dependency, and many more. Developers can use command-line interface accessibility to import libraries in REPL. The executable build also has been eliminated. 

Standard Library 

Though the standard library was available in the previous version, new features have been added for easier library management. More flexibility with string interpolation, performance boost because of UTF-8 encoding, Raw text Support, SIMD, Result vector types are, among others. Any developer currently preparing for a project from specialized iOS app development services should skim through the versions above. 

Power of Enumerations with Result Type  

When we program anything, the result is either positive or negative. Either the result is success or failure. This is a normal thing. To make this thing more valuable and identical, swift has introduced library standard type: result type. So, now developers can get the possible result, and the errors can be also identified in an object. 

Application Binary Interface Stability  

The latest Swift UI application development for iOS provides a revolutionary feature update. Swift UI or UIKit allows the developers to design smooth, interactive interfaces. Developers can incorporate view controllers, labels, and buttons into their app and control various events. The Application Binary Interface does not require you to download and install any gadget, system, or library. Since it can access the current code on your phone, which saves memory space on your phones. 

Simplify Text Processing  

In the previous Swift language version, we could only count the letter of the letter username given to verify if the small and capital letters have a Unicode scaler. However, with the latest version, we can still perform simple text process by directly adding some properties to countercheck them. 

Language and Compiler Upgrade  

Inbuilt-exclusivity enforcement has also been implemented in Swift UI to work perfectly with the debug and release build and to seamlessly manage the memory. If so, are you excited to see the dynamic callable types in action and the interoperability management? With the latest version of Swift UI 5 to be used in iOS app development, it will work with high-level languages such as Python, JS, and Ruby. 

Raw Strings  

The latest version of Swift UI allows you to play around and test regular expressions and user-cases. The strings are enclosed within the quotation marks or hashtags, and the backslash is considered literal as well. Thus, you may interpret them as raw strings with the help of hashtags at the start and end. 

Nested Optionals With “try?” 

With the release this latest, boosting up the swift programming experience while increasing the code readability. Whenever adapting, you also face the optional chain behavior, which could stop any activities from confusing, non-relevant. All is done using flattening the nested optionals and combine the results with “try?” 

New function is Multiple(of:) for integer multiples 

In the early days of Programming with C, you will have to make a program to find out whether the number is odd or even and so on, such kind of the program is written using remainder (%) operator to know the number can be divisible by another number. Swift 5 have found a new function called Mutiple(of:). You can find it in the auto-completion tool. It can improve the code readability and save time as you no longer have to write multiple lines. 

Functioncall “count(where:)” 

We have seen every little updated version comes to make the developers life easier in shortening the time and reducing the hassle. The same functionality also defines the new function call count(where).  

We can see we already have three collection functions to call the values and align the code. When we call map(:), reduce(:), and filter(_;), we need to call three times on an average if we really need to reduce the code, with the count(where) we can reduce the count and sort the things faster. 

“compactMapValues()” Function Launch  

If you have already practiced Swift’s previous version, you may know that there were two functions to get to work with the array items and dictionary. One is to return the resulting array by map(:) and to ignore nil array, compactmap(:). There is also a function for dictionaries mapvalues(:).  

With the latest version of Swift5, compactmapvalues(:) handle efficient mapping and filtering capabilities. It combines the ability of both compactmap(:) and (_:)mapvalues. 

String Interpolation  

All the aforementioned features make iOS app development efficient, flexible, and impressively characteristic. 

Not to forget, string interpolation is also reworked to allow full control over objects, and with the help of struct, you can carry out reasonable debugging.  

In addition to this, in the Swift 5 string interpolation system, expandability appears, which allows you to adjust the string for the class to your liking—you can now add extensions or methods.

Frequently Asked Questions
Is Swift enough for iOS development?

To build an iOS mobile application, specifically for the iOS platform, Swift should be the first choice.

Can you make iOS apps with Swift?

Today, you can create an entirely new application with Swift or start using Swift code to implement new features and functionality in your app. Swift code works side by side with objective-C and C ++ files that are already in the same project, with access to your Objective-C and C ++ APIs (Application Programming Interface). 

What is Swift 5 in iOS?

The Swift 5 is the fifth release of the major Swift programming language. As some people might know, Swift 5 has been developed by Apple. This version of Swift is the fast, safe, and expressive open-source language that enables building iOS, macOS, watchOS, tvOS, and Linux applications.
