  • Can you give me a non-techie Objective-C vs Swift comparison?

  • Objective-C is what Apple has had its OS written in for years. Swift is what Apple now says

  • they want their OS written in for next year and beyond.

  • Objective C has a reputation for being hard.

  • It is. It is the C language, with its complicated syntax and grammar, with a lot of classes

  • and manipulations to make a functional language an object oriented one.

  • How is Swift different?

  • Swift is a new language designed from the beginning to be object oriented. It is expected

  • to be a lot easier to create commands, classes, references and so forth with objects.

  • I would not object to that. So why is not Swift getting picked up faster?

  • Google came out with Go and Dart. Go gets used by Google for applications on its concurrent

  • servers, but Dart missed the mark and is almost never used.

  • Swift is mandated by Apple.

  • But a lot of their stuff is already done in Objective C. And a lot of new projects will

  • still be done in Objective C, because that’s what the programmers know.

  • It is also the language of the code modules they can pull from to build new stuff quickly.

  • Unless Swift is like Scala, where you can plug in Java code and it still works in Scala

  • programs.

  • The methods and properties and so forth are pretty much the same.

  • In theory, there’s no difference between reality and theory. In reality, there is.

  • Objective C has the benefit of being established, and almost all code and all third party libraries

  • are in Objective C.

  • So learning Swift won’t make me first out of the gate to get a programming job.

  • Even with the 2014 roll-out of Swift, the user community is small, so there are not

  • as many online resources or question and answers on Stackoverflow to help you get good with

  • it.

  • But rewriting all the existing code in Swift would provide employment.

  • In the future, sure. But right now, only Apple hires people with Swift knowledge to develop

  • the iOS8 and Yosemite OSX.

  • Not too different from Objective C.

  • If you want to work today, learn Objective C first and then learn Swift.

  • Because I have to know both to convert them anyway. What are the major differences between

  • them?

  • Swift is a beta language, so it may change. For example, Swift’s developers said they

  • probably have to change its syntax and behavior.

  • I cannot learn something that’s always changing like that.

  • There have already been a lot of changes to Swift, and it is going to change more. It

  • is having problems in testing with auto-complete and syntax.

  • So wait to learn Swift until there’s a final version, just so I do not get obsolete in

  • an old version.

  • The worst part is that the Swift code you write today could be obsolete with the final

  • version of Swift, when they officially have Swift 1.0.

  • So learn Objective C today to get to work, and wait until Swift actually works before

  • trying to learn how to work in it.
