Swift programming language features, advantages, disadvantages

Swift programming language has speedily become one of the quick-growing languages in memoir. Swift makes us develop software that is incredibly fast, robust and secure. This reduces the initial size of the Swift app making it the most performing app.

In Swift, you can return multiple values from a function as opposed to only one value. Other C languages allow you to return multiple values using pointers, structures, or arrays. But Swift allows you to return multiple values from functions using tuples, returned as a single entity from a function. Tuples are unchangeable or fixed sets of elements arranged in an ordered sequence. “In some of our projects, we used the MulticastDelegate that allowed us to create one-to-many delegate relationships, i.e., to inform multiple objects whenever a change has happened to another object. That greatly improved the performance of our app and helped avoid tons of bugs.

  • Both languages have different capabilities and can be used together for mobile app development.
  • Secured connectivity enables corporates to process electronic payment transactions internationally superseding electromechanical interfaces such as telex.
  • This feature allows current Swift apps to link against newer versions of the Swift language as it evolves over time.
  • It was the primary programming language used for OS X and iOS development before Swift came along in 2014.
  • So, within its seven years of existence, Swift acquired a large supportive community and an abundance of third-party tools.

Also, its code has good readability and is understandable not only for experienced, but also for beginners. Swift’s syntax has been noticeably simplified compared to Objective-C, and the amount of code has also been reduced.

Short-term liquidity has become a pressing concern for various corporate clients of banks and making best use of cash balances and minimising external borrowing is critical. In order to minimise their reliance on external borrowing, corporates are taking a much closer interest in who is holding their cash balances. Even more significant, are losses that occur if available cash exists but cash managers are either not aware of it, or don’t have an efficient means to move it. If cash is in one bank account but needed in another account, and the corporate ends up borrowing funds from the bank to cover the shorted account, that is an unnecessary cost.

Swift can also appear to be pigeonholed as only an iOS/Apple/Mac language because of the smaller community and features designed for use with Apple products. Specifically designed to be safer than C-based languages, Swift eliminates entire classes of unsafe code as a preventative measure and allows for “cleaner” code with fewer runtime crashes. In most cases, the native Apple’s IDE Xcode will be enough for Swift engineering.

Thanks to this, developers can easily rewrite their projects from Objective-C to Swift, as well as use O-C functionality inside Swift projects. Swift demonstrates a very decent speed of code execution and program operation. Apple claims it is 8 times faster than Python or Javascript and 2.5 times faster than Objective-C. These are Apple’s official frameworks, the first is used when developing software for MacOS, and the second when creating applications for the iPhone, iPad and iPod Touch. Swift has been influenced by many programming languages, including Objective-C, Python, Ruby, C#, Haskell, Rust, and many more.

That means the code will be portable to all platforms that Swift supports. Being a new language, Swift supports only iOS 7 and macOS 10.9 or higher. If you have a reason to build or maintain apps that should run on older versions, you don’t have any other choice rather than using Objective-C. You can only use Swift in the apps that target iOS7 and later.

He has an overall experience of more than three decades in the IT industry. His area of interest lies in writing interesting pieces of content mostly on topics relevant to different types of CMS platforms. He wants to ensure that readers get acquainted with multiple web development tools & techniques so that we can build a technology-driven world for the future. Whenever mobile app-making organizations start a new project in this cut-throat competition, programmers take time to choose between Objective C and Swift.

Effortless Maintenance of the Swift

It is the most easy-to-develop code because you can use the flow of natural English. Unfortunately, many corporate treasury departments are not among the highly supported corporate IT groups, such as customer care, point-of-sale and collections. Consequently, treasury managers are easily tempted ios swift vs objective c to outsource the applications used for bank account management, cash forecasting and centralised payments. While this may accomplish short-term results, the major benefits of integration with SWIFT are still confined in all the other corporate supporting systems running on internal networks.

Secured connection of SAP ERP systems for payment receipt and information retrieval. Security against failure and access protection in multiple installations with maximum recovery ability. High security standards using encryption, distributed digital signatures and the four eyes principle. Route status to credit systems and customer relationship management , and reduce credit balances so that more receivables can be incurred. SWIFT has seen a tenfold increase in the number of corporates connected in just the past four years. Let’s take a detailed look at how Swift brings a plethora of long-term benefits for businesses.

Advantages of Swift

Instead, method and function calls in Swift use the comma-separated list of parameters within parentheses. Swift consists of a vibrant and active open source community. We can also see that Swift is the second most starred language. Swift consists of abundant resources to help every developer accelerate better adoption. It also has a huge set of podcasts, community guidelines, real-life courses, Swift playgrounds with gamification for the learning experience.


In further phases, these processes can include supply chain systems via integration with RosettaNet for matching physical goods directly against financial transactions in a single view. A big part of making a choice between programming languages is your team’s experience and preferences. If your developers are skilled at Objective-C, having them all migrate to Swift may not be an option.

An array is a collection of similar elements grouped together for easier referencing and indexing. Since Swift already knows what kind of data your array holds, it can quickly and efficiently run blocks of code by assigning every element in an array a constant that you name. There many advantages to programming in Swift, beyond the creation of iPhone apps. It’s very important that a developer can use the established solutions instead of writing their own bicycle. However, there are other useful tools for different purposes that can enrich the standard Swift capabilities. For example, Alamofire is a powerful HTTP networking library for iOS and macOS that helps simplify a lot of networking tasks.

About the Company

Swift uses Automatic Reference Counting – a technology aimed to add a garbage collector function that wasn’t introduced to iOS before. Languages like Java, C#, and Go use garbage collectors to delete class instances that are no longer used. They are useful to decrease your memory footprint but can add up to 20 percent to CPU. Before ARC, iOS developers had to manage memory manually and constantly manage retain counts of every class.

Swift, however, drops this two-file requirement, combining the Objective-C header (.h) and implementation files (.m) into a single code file (.swift). In Objective-C, you have to manually synchronize method names and comments between files. While with Swift, programmers can spend more time creating app logic and improving the quality of their code, comments, and features that are supported.

Advantages of Swift

Use open-source Swift across major platforms like Windows and Linux. This makes the language particularly ideal for mobile developers. https://globalcloudteam.com/ While Swift runs across other platforms, keep in mind you’ll need cross-platform programs like Sublime Text or Atom.

That is, despite speaking the same root language, they still need help to communicate due to dialect and localisation differences. With the help of a SWIFT transfer, you can make transactions in any currency and to any bank in the world. However, its implementation takes longer than a regular online transfer, on average about 3 working days. It is not always possible to determine the cost of a transfer in advance, since it depends on how many banks will act as an intermediary in a particular transaction.

Interoperability with Objective-C

Swift takes a lot of useful components from Objective-C while also bringing a whole new host of features, allowing developers to write safer, more reliable code. It has quickly become the leading programming language for creating engaging, user-friendly mobile apps. An increasing number of medium- and large-sized corporates with international business operations and high payment transaction volumes are directly connecting to SWIFTNet. Hence, the speed of the Swift application gives an edge to the functionalities over other app development languages.

Deferring the ‘how’ discussion for a moment, calculating whether SWIFT connectivity , makes sense for a corporate is fairly simple maths. In addition, consolidation of that data into a decision-support report suite, or dashboard, is severely lacking. The innovation of the Swift app has made it possible to do interactive coding. The additional feature, the Playground, enables the Swift development which helps test a new algorithm.

Its typing interface reduces the possibility of bugs remaining overlooked. To get started learning these concepts and more, check out Educative’s course Swift Programming for Mobile App Development. In this hands-on course, you’ll cover topics ranging from arrays, dictionaries, integers, object-oriented programming, error handling, and more. By the end, you’ll have the foundational knowledge you need to begin diving deeper into Apple-based app development.
