Swift is an iOS, OS X, watchOS, and tvOS programming language that combines the advantages of C and Objective-C, but without the C compatibility problems. Swift adheres to safe programming practises while while adding cutting-edge features to make programming easier, more adaptable, and entertaining. Swift is friendly to new programmers and familiar to Objective-C programmers.
Objective-C is the primary programming language for creating apps for OS X and iOS. It’s a superset of the C programming language, and it’s an object-oriented programming language with a dynamic runtime. Objective-C adds class and process declaration syntax to C’s syntax, primitive types, and flow control instructions.
