They both had prior knowledge of Smalltalk while at ITT Corporation's Programming Technology Center, which further equipped them to develop Objective-C.Īfter creating the Objective-C programming language with class libraries, Cox and Love created the PPI, which they intended to use to aid the commercialization of their product. The Objective-C programming language was invented in the 1980s by Brad Cox and Tom Love. One of the main benefits of Objective-C is its ability to dynamically load code, meaning you can use it to create small, lightweight programs or large, complex programs. It’s a superset of the C programming language, meaning it can do everything C can. The Objective-C programming language is an object-oriented language used to develop various apps and software, including iOS and OS X. Read on to learn more about features, pros, and cons of Objective-C and Swift languages. It uses lazy initialization, reducing memory usage since unused variables do not initialize-making it faster, easier to read and write, and safer. Swift has better memory management features than Objective-C, which can help improve performance. A type-safe option like Swift can make code more reliable and easier to debug.
In addition, Swift is more type-safe than Objective-C, meaning that it is less likely to produce unexpected results due to type mismatches. Swift also has a more concise syntax that makes it easier to understand code at a glance. For starters, Swift is easier to read and write than Objective-C.
There are many reasons to choose Swift over Objective C. However, Swift has dynamic libraries that help boost the iOS app development performance. Swift's variables can only hold values of a specific type. Objective-C is a dynamically typed language hence variables can hold values of any type. Swift uses value types instead of reference types, which means variables are assigned a new copy of the data whenever they are modified. In contrast, Objective-C's categories run directly in compile time and can only be used to extend the functionality of a specific type. Swift's protocols enable you to write code that can be applied to any type that conforms to the protocol without knowing the specific type. This means that you don't have to explicitly declare the type of a variable, which can save time and make your code more concise. Swift has type inference, allowing the compiler to automatically infer the type of a variable based on its value. Swift is newer than Objective-C and has many features that Objective-C does not.
