Objective-C is actually a superset of C with addition of object-oriented features and dynamic runtime. For a long period, Objective-C was the important programming language used for developing OSX and iOS applications for App Development.
Apple introduced a new programming language in year 2014 called Swift which was described as “Objective-C without the C”. Swift is safe, fast, modern and empowers the level of interactivity in iOS mobile app development. It carries a number of features like closures, generics, and type inference that make it easier to use, simplifying regular patterns utilized in Objective-C.
Swift is easier to read
The main favourable position to picking Swift is ostensibly a result of its spotless syntax, which makes it simple to read and write. The quantity of code lines need to implement an option on Swift is a lot fewer than for Objective-C. The purpose behind this is because Swift drops numerous legacy conventions, for example, semicolons to end lines or parentheses that encompass conditional expressions inside if/else statements. Another real change is that technique calls don’t sit inside each other bringing about a section mess Rather, method and function call in Swift utilize the comma- isolated list of parameters within parentheses. Thus, the code is cleaner with an improved syntax.
Swift requires less code
Swift is a more compact language for programming. Less code equals better readability. This fact doesn’t imply code simplicity, of course. Sometimes, it can be very difficult to write, but brings more benefits, being highly reusable. The latter point cannot be applied to Objective-C.
Swift is faster
Swift also gives different speed benefits during development, in turn, saving on costs. An unpredictable object sort, for instance, will run 3.9x speedier than a usage of a similar calculation in Python. That is additionally superior to Objective-C, which is 2.8x speedier than the Python variant.
Swift is open-source
Swift was announced open-source in 2015, which opens up the language to the potential to be used across a variety of platforms and for backend infrastructure. Open-sourcing Swift means that Apple will be able to get feedback from the community to make improvements on a consistent basis as independent developers contribute to the success of the language. Not only has Swift taken off successfully because it’s well structured and designed, but also because many developers have supported it.
Swift also Supports Dynamic Libraries
Dynamic libraries are executable lumps of code that can be connected to an application. This component permits current Swift applications to interface against newer versions of the Swift language as it advances after some time. Dynamic libraries in Swift are specifically transferred to the memory, eliminating the initial size of the application and at last expanding application execution.
