Top 10 new features in Swift 5 you should consider during iOS app development



From this article you will discover:

  • 10 new and advanced features of the Swift5
  • Detailed explanation and examples of Swift 5 features

If you are a startup owner or entrepreneur of a business with a plan To develop your iOS app for your business, you can quickly look at this blog. Here we have covered 10 new and advanced features in Swift 5 programming languages ​​that can be the right choice for your iOS app development. So let's explore 10 features of Swift with detailed information and examples.

A completely new version of the Swift programming language is here. Swift 5.0 brings a number of changes as well as some new features to make development even easier and better for fast app developers.

Today we will look at some of the most important changes and new features in Swift 5 . We will also discuss how the process of making changes to the Swift language actually works and why any iOS developer should know about it.

Swift software language was originally released in 201

4 and opened at the end of 2015 As a result, more than 600 contributors have joined and are actively improving the language for seamless development of iOS apps.

After Object-C, Swift was originally the "other" languages ​​for apps in the Apple ecosystem. But since Swift is open source, it can be used on a number of other platforms, especially Linux.

This also led to the development of the server side Swift so that it can be used as a back-end language for web services. But why do we discuss all this? It's important to realize that Swift is bigger than just building iOS apps. So, without further ado, let's get right to the topic and learn Swift programming features with an updated process.

What is the Swift Programming Language update process?

  • First, all the changes are proposed in the Swift programming language. and discussed in a GitHub archive called Swift Evolution .
  • Anyone interested in the language may suggest the changes, but they must follow a process. You will find many suggested changes that are discussed first, in Swift Forums and then in communities.
  • After that, each proposed change is publicly reviewed by the Swift core team, which consists of Apple engineers such as Ted Kremenek and Chris Lattner. You can find a list of current and past suggestions in the suggestions [SwiftEvolution's catalog.
  • A typical suggestion usually includes source code and technical design. If the proposal is accepted, the given source code is merged into the Swift source code.

Swift Evolution is more than just making a good programming language. It also rejects suggestions to ensure language integrity and robustness. If you are interested, check out this SE – 0217 a rejected proposal for the bangbang operator!

New features in Swift 5.0 Programming language for effective iOS App development

1. ABI Stability

The most important highlight of Swift 5.0 is ABI stability. ABI stands for Application Binary Interface, which is a binary equivalent to an API, an Application Programming Interface.

iOS app developers use different APIs for libraries to write code for your apps. For example, the UIKit framework provides API with interface with buttons, labels, and display controllers.

When ABI downloads and installs your app, ABI does not need to download all the code your app requires. Most of these tags are already present on their iPhone, as part of iOS, frames and libraries. Your app must only use the binary code already present. This will make future apps smaller and easier to build.

2. Whole number multiples with "isMultiple (of :)"

There are many uses in practical programming. One of the most common is to check if a number can be shared with another number. Since it again requires checking if a number is smooth or strange, the default approach is to use the rest operator%.

Swift 5 has a new function isMultiple (off 🙂 to check if a given integer is a multiple of another number. This feature improves the readability of the code and can also be detected by automatic completion of XCode.

  Example Usage:

la number = 42
if number.isMultiple (of: 2) {
print ("(number) is smooth!")
} 

3. Result Type

Swift introduces a new type called Results for iOS app development. This type works with two states of success: success and failure, and because of its high popularity, it is now available in the standard Swift library.

Result type encapsulates possible return values ​​and errors in one object. It utilizes the power of enumeration and helps you write a more meaningful code.

  Example Usage:

data task (with: url) {(result: Result ) i
change result {
case la. success (data):
handleResponse (data: data)
case let .error (error):
handleError (error)
}
} 

4. Filter and count with "count (where :)"

You may already be familiar with aggregate functions such as maps (_ :), reduce (_ 🙂 and filter (_ :). The problems with the features above are – they make the code for verbos and waste. Although we just want to count, we must first filter, and that's where ‘tell (where 🙂 comes in. This feature allows us to filter and count in a function call seamlessly.

  Example Usage:

la score = [1, 3, 8, 2, 5, 6, 2, 10]
la count = scores.count (where: {$ 0> 5})
print (count)

Output = 3 

5. Flatten Nested Optionals With "Try?"

Although it is not wrong to use nested operators, they are confusing and unnecessary. Sometimes they need a larger number of operations to do a simple task themselves. Does Swift level the nested optional result from the test? Give them the same behavior as? and optional chain. This also helps the developer keep the code neat and clean.

  Example Usage:

if let engine = (try? bike? .getEngine ()) as? Engine {
// That's it
} 

6. The new "compactMapValues ​​()" function for dictionaries

The default library has two important functions for matrices and dictionaries.

map (_ 🙂 – It uses an array element function and returns the resulting matrix.

compactMap (_ 🙂 – it discards zero array elements.

On the other hand, the MapValues ​​(_ 🙂 feature does the same for dictionaries, except that it does not discard the elements with the null array. Swift 5 bring compactMapValues ​​(_ 🙂 function for dictionaries.

It basically combines the compactMap (_ 🙂 function into matrices with the mapValues ​​(_ 🙂 function of dictionaries for effective mapping and filtering of values.

7. Standard Library Updates

The default library of Swift 5 contains many new features that help Swift programmers manage their libraries well. Some of the most important are as follows:

  • Improved Raw Text support for string literals.
  • SIMD and Result vector types are now available in the Swift Standard Library.
  • Strict renewal with UTF-8 encoding for performance increase.
  • Added more flexibility to construct text from data by improving String interpolation.
  • Performance improvements in the Dictionary and Set

8. Package Manager Updates

Swift 5 brings a host of new features to the Swift Package Manager. It includes target-specific building settings, custom distribution targets, addiction mirroring, etc.

Furthermore, you can now import libraries into a REPL using the Quick Run command without having to build an executable.

9. Additional Language and Compiler Updates

Swift 5 comes with exclusive enforcement at standard values ​​and provides exclusive memory access for both debugging and publishing buildings. It now supports dynamic interruptible types and helps improve interoperability with languages ​​such as JavaScript, Python and Ruby.

Swift also added literal initialization via force, identity key path and other suggestions as a result of the Swift Evolution process.

10. Migrating to Swift 5

Finally, if you are impressed with the Swift 5 features and look for migration. There is nothing to worry about. Swift 5 is compatible with Swift 4, Swift 4.1 and Swift 4.2 for the effective development of iOS apps.

You just need to use Apple Xcode 10.2's code transfers, and many of the changes will automatically be handled by the code transfer provider. You can also use the Migration Guide available on the official site.

Final Words

Swift 5 comes with light syntax and combines powerful type of inference and pattern matching. The new version not only allows Swift developers to express complex ideas in a clear and concise manner, but also improves the readability of the codes during the iOS app development.
