![]() Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Apple is already changing the nomenclature of the cocoa framework methods to adopt Swift naming conventions, so they aren't really waiting for anything. Objective-C is the primary programming language you use when writing software for OS X and iOS. And at the end of it all they will be Swift frameworks, so general knowledge will not be wasted, but specifcia knowlege may very well be wasted. all of those frameworks are destined for change in the near-mid future. You will need to understand the general layout and design structure of a Cocoa framework, and then get very good at Swift. I suggest doing a few intro tutorials to Cocoa, and then moving completely to Swift. This is the best approach for anyone coming to programming for the first time. It was first introduced by Apple at WWDC 2014. Apple notoriously quotes Wayne Gretzky : skate to where the puck will be. A new Swift programming language from Apple can be best described as Objective-C without the C. It's very mature, hugely powerful because of its dynamic runtime, which Swift doesn't have, and will never have, and it will never break because Apple will never change the ObjC runtime now. However, based on various information resources (such as GitHub, StackOverflow), it can be concluded that the popularity of Swift continues to grow. Objective-C / Swift Firstly, there's totally nothing wrong with considering ObjC. The real challenge isn't learning Obj-C it's learning Cocoa, which takes the quirks of Obj-C and adds quite a few more (that made a lot of sense when they were written.) But you will learn Cocoa regardless of which path you choose. Apple does not provide public statistics, and there is no a single comprehensive Objective-C vs Swift comparison regarding their popularity and usage online. So, if we review the OP, the question is about learning Obj-C vs Swift. On Apple systems, Swift uses the same runtime as the extant Objective-C system, but requires iOS 7 or macOS 10.9 or higher. You cannot interact with the OS at a high level of abstraction without interacting with Cocoa. Its important to have the words defined because Cocoa is. Swift : a computer language, written in response to user requests for Obj-C. ![]() Foundation: a set of OS frameworks, written in C and C++ that under pins Cocoa frameworks. Cocoa : a set of OS frameworks, originally written in Objective-C. In the meantime Cocoa is accessible from Swift. Objective-C : a computer language, based on C. It's important to have the words defined because Cocoa is destined to be written in Swift. Swift : a computer language, written in response to user requests for Obj-C Objective-C : a computer language, based on CĬocoa : a set of OS frameworks, originally written in Objective-Cįoundation: a set of OS frameworks, written in C and C++ that under pins Cocoa frameworks. some definitions are in order so we all know what we are talking about
