In the past few years, iOS development has become more popular and affordable with the advent of Swift programming language, Apple's new programming language for iOS.

One of the reasons for its rapid evolution is its open nature and ability to accept changes from anyone within the community. As a result, the syntax taken from adding a comment to the text has changed over a short period from the previous idea.

Due to the ever-increasing demand for Swift developers, many engineers have started to focus on developing apps for smartphones and tablets. Despite this, expertise with iOS goes far beyond simple coding skills. Although Swift is an excellent programming language, it can positively impact the entire application if implemented correctly.

Here are some mistakes that some Swift App Development Company are likely to make out of negligence when working with Swift and ways to avoid them.

What is the Swift Language?

Apple Inc. has developed Swift, a powerful programming language that you can use to create powerful apps for your iOS devices, iPads, macOS, tvOS, watchOS, and Linux systems.

Using Swift, users get the best of both worlds: Apple's decades-long experience combined with the latest advances in programming languages.

Why Swift App Development?

Regarding the speed of development, Swift has a 100,000-fold faster development speed than many other languages. As a result, it is beneficial for a company to Hire Swift Developers so that customers can benefit from applications with better performance. In addition, it features a high-speed search solution, allowing the swift application to live up to its name.

Common mistakes iOS developers make while working on the Swift programming language

Most Swift programmers come from an Objective-C background, among other reasons, making it likely that they will write Swift code like they are used to writing other languages. This can result in errors.

Below are the most common Swift developer mistakes and how to avoid them.

Using self Everywhere

The Swift programming language does not require using self to access classes or structs' properties. There is only one case where we need to do this in a closure: it provides the function to capture the self.

When you use self where it's not required, it's not a mistake. It works fine, and there won't be any warnings or errors. Writing more code is okay, but do just what is necessary. Furthermore, it is also crucial to maintain consistency throughout your project.

Strong Reference Cycle Pitfalls

Two objects must keep a strong connection to establish a strong reference cycle. This problem is not unique to Swift, considering that Objective-C has the same problem, and experienced Objective-C developers know how to deal with it effectively. Having strong references is essential.

Codable Power

A replacement for Objective-C's clunky and outdated NSCoding system was desperately needed, so Apple finally responded to the many voices calling for a replacement in Swift 4. With the Codable protocol (which comprises two protocols, Encodable and Decodable), each type can have a blueprint that can be used to serialize the type to any format you want (JSON, XML, etc.). Codable is generally used to parse data objects from JSON provided by networks.

Type Uncertainty

The Swift programming language uses type values and reference types. Furthermore, instances of value types behave a little differently when compared to instances of reference types. Knowing what category each of your instances falls into, you can form accurate expectations about the code's behavior.

The object-oriented paradigm expects class instances to always be the same, such as in methods and when passed around. That means any change to it will be reflected everywhere because we have just a bunch of references to the same data.

Using storyboards rather than XIBs

According to Apple's suggestion, most new top Swift application development services providers implement the UI using storyboards by default. Despite the above, it is essential to recognize that the use of storyboards has a lot of disadvantages and few advantages.

Using Enums inefficiently

Most consider enums a list of related constants enclosed in integers, representing the basic C enum. The power of enums is tremendous in Swift; for instance, each enumeration case can have a value attached.

As well as having read-only/computed properties, enums have methods that can supply additional information to each case, providing them with more details and information.

The documentation on enums in Swift is very intuitive, and many use cases can be derived from the error-handling documentation, demonstrating the enhanced power of enums.

Conclusion

As Swift evolves and gains new features, it will improve. Making the most of its toolkit is essential. Besides reducing your code writing time, it will make your code much safer to execute. Moreover, when you Hire Swift Developers, your business can develop an app that will bring growth and customers.
