Swift is a general-purpose, multi-paradigm, compiled programming language created for iOS, OS X, watchOS, tvOS and Linux development by Apple Inc. It is an alternative to the Objective-C language which was the recommended and most popular language for building apps for Apple’s ecosystem of devices.
Swift, rightly named after the Swift bird (which is among the fastest fliers in the animal kingdom), was developed to be a faster alternative to Objective-C. Other than speed, Swift offers other advantages over Objective-C, including ease of learning, safety, requires less code, is interactive, among other things. Compared to Objective-C, Swift has a simpler syntax that makes it easier to learn for beginners or for anyone coming from another programming language. The language took language ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list. This means that programmers coming from other languages or from other platforms (such as web development) will find a lot of concepts in Swift similar to what they were used to.

The number one advantage to choosing Swift is arguably because of its clean syntax, which makes it easier to read and write. The number of code lines needed to implement an option on Swift is a lot fewer than for Objective-C. The reason for this is because Swift drops many legacy conventions, such as semicolons to end lines or parentheses that surround conditional expressions inside if/else statements. Another major change is that method calls do not sit inside each other resulting in a bracket mess. Instead, method and function calls in Swift use the comma-separated list of parameters within parentheses. As a result, the code is cleaner with a simplified syntax.
It’s not possible for Objective-C to evolve without C evolving first. Contrarily, Swift does not have these dependencies, which makes it a lot easier to maintain. C requires programmers to maintain two code files in order to improve the build time and efficiency of the code, which also carries over to Objective-C.
In the competitive mobile app marketplace, developing a secure app should be a priority. Swift’s syntax and language constructions exclude the several types of mistakes possible in Objective-C. This stability means that there will be fewer crashes and cases of problematic behavior. It doesn’t prevent programmers from writing bad code, but rather makes it less likely to make mistakes. This adds an extra layer of quality control during development.
With Objective-C, there are many issues that cause app crashes. Swift provides code that is less error-prone because of its inline support for manipulating text strings and data. Additionally, classes aren’t divided into two parts; the interface and the implementation. This cuts the number of files in the project in half, which makes it much easier to handle.
Swift also provides various speed advantages during development, in turn, saving on costs. A complex object sort, for example, will run 3.9x faster than an implementation of the same algorithm in Python. That’s also better than Objective-C, which is 2.8x faster than the Python version.
