• 01.

  Powerful generics.

  Generics are powerful because they allow developers to write flexible, reusable functions and types that can work with any type.
• 02.

  Native error handling.

  Swift provides the ability to throw, catch, and manipulate errors at runtime.
• 03.

  Structs and classes.

  Swift allows you to define a structure or class in a single file and make the external interface available for use by other code.
• 04.

  Protocol extensions.

  Swift enables you to define behavior on protocols rather than global functions or individual conformances.
• 05.

  Memory safety.

  Swift manages memory automatically and prevents unsafe behavior in your code.

• 06.

  Memory management.

  Swift tracks and manages our app's memory usage using Automatic Reference Counting (ARC). This means we don't have to worry about memory management.
• 07.

  Flexible enumerations.

  Swift enums can have payloads and support pattern matching.
• 08.

  Package manager.

  The Swift package manager is a cross-platform tool for building, running, testing, and packaging Swift libraries and executables.
• 09.

  Debugging.

  Swift employs the LLDB debugger, which includes a REPL and a debugger for integrated debugging, consistent formatting, failure recovery, and expression evaluation.
• 10.

  Closure syntax.

  Swift has a lightweight closure syntax that has been optimized for clutter-free syntax and clarity.

Swift

• Swift allows you to develop in Xcode, Swift Playgrounds, Cocoa Touch, and other environments.
• Swift is a modern, human-friendly language with a simple syntax, which means faster coding.
• Swift, according to Apple, is 2.6 times faster than Objective-C.
• Swift has extensive documentation that is constantly being updated.
• The need for Swift developers is growing.

Objective-C

• Objective-C is primarily used to develop apps in Xcode.
• Because the language is less intuitive and human-friendly, using Objective-C typically results in slower coding speeds.
• Objective-C is 2.6 times slower than Swift and requires more time to write due to its more complex syntax.
• Objective-C has extensive documentation, but it is rarely updated.
• Objective-C developers are in short supply.

  It is still relatively new on the market

  Apple Inc. recently released Swift to the market. It debuted on June 2, 2014, but its official release date is April 21, 2017. (3.1 version). As a result, it is still new in comparison to Objective-C. Objective-C, on the other hand, was released around 33 years ago and was essentially a continuation of the C-language. Apple had to release it separately because it was not yet ready to support Objective-C functionalities.
• 02.

  It’s open-source

  The Swift Development Language was developed in an open course, making it easier for users to upgrade all source codes, bug tracker, and email list at regular intervals. Because of its robustness, it is possible to read the technical documentation. This directly contributes to the development of future applications. Furthermore, it supports all Linux-based platforms.
• 03.

  Comply with Data at a Much Faster Rate

  Compared to Objective-C, Swift is capable of managing data at a much faster rate. It has been using the LLVM compiler to generate optimized native code for operating systems. The developer is given the option of rewriting several groups as structures. In the case of Objective-C, there were only a few classes, which resulted in slower coding and, as a result, a longer time frame. Swift takes less time to code than other languages, as previously stated.
• 04.

  The Right Language for Creating Business Apps

  Its efficiency has been demonstrated through numerous tests and other activities, and it is thus regarded as one of the best programming languages for developing business apps. The company (Apple) has on board the most skilled developers, who are constantly working to make it more user-friendly.

• 05.

  Reduces Memory Usage

  Swift once again outperforms Objective-C in terms of memory consumption. The latter had an object-link and used some of the computer's RAM (Random Access Memory). Swift, on the other hand, was a single object-oriented program that switched to structures. The number of data types and SDK classes was also reduced, making memory more efficient.
• 06.

  Not limited to use only for iOS Development Apps

  You might believe that because Swift was developed by Apple, it is suitable for developing iOS-based mobile apps. However, this is not the case. Though it has been adapted by Linux and other programs, it can also create useful and fully functional apps for Android.
• 07.

  It takes less time to code

  When developing an app in Swift, you will most likely only need a few lines of code. As a result, not only is your job easier, but you can complete your code creation work in a shorter period of time.
• 08.

  Safety Storage of Data.

  It has an integrated storage system for safe data storage. Apart from that, it is simple to understand if you want to become an iOS app developer, and any type of business, whether large or small, can benefit from it.

Hire a freelancer Swift Developer

Pros

• Cost-effectiveness means that you just pay for the work itself;
• Large skill pool: you can work with the expert you want.

Cons

• You must pick the experts for yourself;
• Due to the several tasks that freelancers frequently have going at once, it may be difficult to meet deadlines;
• Unexpected absence.

Hire a Swift developer from agency

Pros

• Time, money, and flexibility savings because there is no need to hire, train, or pay salaries;
• You have access to a huge pool of qualified, talented experts that are eager to get started.

Cons

• The institutional knowledge of your organizations may not be known to developers;
• Adding Swift developers to your team could be more expensive, but this will depend on how many hours are needed to do the task.

Hire a Swift developer in-house

Pros

• Every development process is individually overseen by you, and you regularly communicate with the staff to be informed at all times;
• Working together is simpler and there are fewer misunderstandings when everyone takes the same approach and speaks the same language.

Cons

• It can be expensive because you wind up spending more on hiring, corporate perks, and equipment;
• Lack of scalability and flexibility in that you must guarantee that the employees you hire will have work or pertinent projects to work on for the next years;
• They can leave your company in search of a better opportunity.

• You pay only for a developer’s hours.
• You only pay them when you have a job for them to complete.
• There will be no charges if there is no work.
