Swift will change the world

Now if only Google would use that instead of Java...

 

Swift will be a really nifty feature for developers that choose to use it, and will make a big impact. But I don't expect Objective-C to go away anytime soon.

 

....and very Swiftly.

 

Swift will likely be much more optimized than Obj-C on the same hardware. Apple changed to LLVM for a reason. It pays off in the long run.

 

I think it will change the iOS/OSX programming world, but outside of that the impact will be very limited

 

Who cares?

It works alongside Obj-C and C.
It's easy as piss to code.
It looks amazing.
Education will pick this right up.
Developers will be able to rapidly develop using more extensive features.

 

Agreed. I hope it catches on...

 

It's pretty funny since...

I was going to learn Objective-C until this came along. Swift is so crazy!

Now...I'm still going to learn Obj-C first. Then transition over sometime in the future.

 

it's not like Objective C was exactly the beacon of platform independence
99.9% of all current Objective-C developers work on apple platform...

also let's be honest: in terms of code-readability Objective-C isn't really that great. For people coming from Java, C# or more modern stuff like Ruby it really feels clunky and hasn't aged well

after looking a little bit into Scala last week and through the first few pages of the Swift programming language book i would say, Swift will be to Objective C what Scala hopes to be to Java


i tried to dive into objective C multiple times and honestly it never warmed up to me. Swift instantly made it onto my "languages-to-learn" together with Scala and Ruby

 

They can't use the same code today. Requiring objective c has not hurt iOS's popularity with developers.

 

While a little strange, it's not as though Objective-C is difficult to learn. Developers will still need to learn how to structure an application, utilise design patterns and learn the APIs, which IMO are much more difficult to grasp than the language syntax.

 

I've been trying to learn a programming language for awhile now, but never knew exactly where to start. Are you saying you are going to learn Swift without learning Objective-C? Everyone always tells me I should start with C then move to Objective C and so on. What do you think?

 

Possibly just a teeny bit of an overstatement?

 

I've been wondering what if Apple completely rewrites iOS 9 using Swift?

 

That would explain the deafening applause from developers in the audience when they announced it.

 

I'll tinker around with it for new app projects. Any and all game code will still be entirely written in c++11. I also have no intent to rewrite my huge objc codebases for my existing apps.

 

I am very excited about Swift! I gave the Swift guide on ibooks a cursory examination and the syntax at least looks a lot simpler than Objective C 2.0 is. Although I still intend to finish up learning the basics of Objective C before I turn to Swift.

My main question, though, can someone develop most apps completely in Swift or is it just an addition to the required objective c? Also, let's say you use a lot of Swift in your app. Will it run on an iOS 7 device once you compile and publish it to the App Store?

I've been plowing in to Objective C for a month or so now as I desire to be able to develop apps by the end of the summer, at least relatively simple ones. I have purchased two online courses (not sure if I can post the names or not) and the funniest thing is that the best tutorials I've found for Objective C have been from a user called "mybringback" on YouTube completely for free. So my advice for you would be to just download Xcode 5 and start with his videos, as I've tried a lot of them and for me personally I learn the best from him. I wouldn't bother learning C first, at least not if you intend to develop for iOS, since it's just not necessary and could be a bit too much if you aren't a computer science major in college and can't do it full time.

 

It's a whole new language and thus doesn't require ObjC. That is why Apple made Swift in the first place. Apple wanted to basically retain the power in ObjC, but have it in a super easy language. It also uses the existing LLVM compiler to compile. So I'm assuming that any targets that run apps compiled with LLVM will run Swift apps just fine. However, wait for the "official information" from Apple, though I'm 99% sure

As someone who knows .NET, I find ObjC an alien language. Swift is a mix of Python and .NET so it will be relativity easy for me to pick up; this is the primary reason why I'm excited for it.

 

Define "changing the world".

 

Native Objective-C can't be ported over anyways. Sure you could share a C++ library if you wanted to, but you can do the same with Swift.

All it really means is that iOS development will have an even lower barrier to entry than before. Not that Objective-C with ARC is super difficult, it just looks daunting to newcomers. Swift is a lot more approachable.

 

Well Swift looks like a bit of JavaScript mixed with VB at the first glance. Personally I don't like the way you define procedures and function return type in Swift I am more objective-c java style guy... But well things are changing I cannot really tell if it's better just after a few weeks using it.

But good initiative to have a new programming language. But for sure a lot of Objective-C code is there I don't expect to go away overnight.

 

I would love to know the names of the online courses you purchased, if that's possible.
