I want to start learning Swift but I am not familiar with Xcode. On the developer apple site you can download a playground that you can use while learning from their book "The Swift Programming Language". But I use an older version of Xcode (v6.2), and the playground is made for version 7. Is there a way of opening the playground without upgrading to the latest version of Xcode? Thanks
You can't. The only workaround is to copy and paste the code.

With the release of Swift 3.0 being available for Mac OS and Windows, does this mean you can compile and run Swift code on Windows? If so what compiler do you use for Windows?
There is an open source project on GitHub that (quote) "provides an easy-to-use development environment for Swift programming for Windows applications": Swift for Windows.
System Requirement
Windows 10 64bit, Windows 7 64bit
NOTE
The project was initially hosted on Microsoft CodePlex, but then moved to GitHub.
Since Swift got open sourced, many more platforms were supported by Swift.
Linux was added shortly after it was open sourced, and just recently, the Android support for Swift was merged into the master branch.
You can track the progress of porting Swift to Windows here. As you might see, it's not currently being worked on actively by the Swift team, there is, however, a community port on Github trying to port Swift to Windows.
It is possible to write, build and run Swift code on Windows. With "Siver" and "Elements".
Silver is a free implementation of Apple's Swift programming language. With Silver, you can use Swift to write code directly against the .NET, Java, Android and Cocoa APIs.
Elements is a compiler and development tool chain for Oxygene, C# and Swift which targets the .NET runtime, Java/Android virtual machines. Elements is developed by RemObjects Software (https://en.wikipedia.org/wiki/RemObjects_Software).

You say:
With the release of swift 3.0 being avaliable for Mac OS and Windows
But this hasn't been announced officially.
There's some projects, but nothing from Apple... yet.
And anyway, the site where you read this:
swift.im/releases.html
is not about Apple's Swift, it's an entirely different project with, unfortunately, the same name.
As far as I know: Swift is available for linux and you can expect swift for Windows, Android soon in the future.
If you want to use Swift language on windows, you must be rely on web based platform. For example: http://swiftstub.com , http://www.runswiftlang.com , etc.
Silver runs on Windows and allows you to compile Swift code to Java and .NET.
Yes, as of September 2020 Swift is available as a binary download for windows. There are even windows-specific instructions for getting started.
The OP asked about which compiler is used. I believe the swift binary is what actually builds the code into an executable. (As of the blog post in 2020, it was CMake, but swift packages are now supported, as well as the swift build command.)
This question is quite old, so no doubt the other answers were all correct when they were written, but this shows up prominently in search results, and should probably have a community wiki answer.
I just downloaded the Xcode 6 GM, and I'd like to see how my apps work with an Apple Watch connected to the simulated iPhone.
How can I simulate this new device on my MacBook?
Install Xcode (starting from 6.2) (link)
Add Apple Watch target to your project (New->Target->Apple Watch->Watch App)
Go to iOS Simulator -> Hardware -> External displays and select any Apple Watch options
Choose '[your project] Watch App' target and Run
Have fun! :)
Xcode 6.0 does not support development for Apple Watch.
Xcode 6.2 supports development using WatchKit. Check out the WatchKit Programming Guide which includes some examples and note issues reported in the Xcode 6.2 Beta Release Notes. Furthermore, be aware that most of the simulator issues mentioned in the Xcode 6.1 Release Notes still apply but were unfortunately omitted from the 6.2 notes.
Xcode does not support development of native apps for Apple Watch, but it was announced as coming in 2015.
Apple has announced WatchKit. Here's an example of what the WatchKit simulator looks like, from the "getting started" video:
There's also a WatchKit programming guide and framework reference, which seem to reveal quite a bit about how the Apple Watch will work.
Also note that while you can't exactly simulate what will truly be available to developers for the Watch, Apple has announced "WatchKit," which is the platform developers will use.
Unfortunately, there has been no release date set.
Watchkit is coming out in November of 2014. They will likely add the simulator in Xcode then.
You must have Xcode 6.2+ to develop app/extension using WatchKit.
This guide gives detailed information about apple watch development including how to run apple watch app in simulator.

As the title,I just want to do some simple practice ranther than big project for I'm just new to Swift language.So is there any way to setup an environment for Swift without 'Xcode 6' installed?THX for answering.
Not at the moment.
The Swift Language is actually new and still in development, evolving day after day.
This means also that new funcitions and classes will be created and modified int the next months. Until then no one will create an "Online Playground" for Swift or similar.
I've planned to make an online Apple Swift Playgroung myself, but that will be once the language has finished developing.
You need XCode 6 to try and use the Swift language, even only in Apple Playground.
You can't use Swift without installing Xcode6. It isn't a stand alone language at the moment.
With each beta of Swift, Apple is changing the language. At the moment [August 2014] noone could make a lightweight environment of Swift, because of these many changes.
If you think that you have to pay for playing around with the Xcode 6 Beta, this isn't true. You don't need the "Mac Developer Plan" for 99 US$/year.
You only need to register as a developer at this page:
https://developer.apple.com/
If you're done, than you can download the Xcode 6 Beta at this page:
https://developer.apple.com/xcode/downloads/
After installing Xcode 6, you can start a new "Playground", which is your lightweight environment for Switch you're searching.
Apple introduced a new programming language for iOS 8 / OS X. Which version of xcode supports Swift?
I am trying on Xcode 5.1, but it is not supported.
Swift programming language was introduced in Xcode 6 beta version.
Xcode 6 has deep support for Swift throughout. It’s easy to create a brand new app using 100% Swift code, add new Swift code or frameworks to existing apps, and view documentation in either Swift, Objective-C, or both. All the popular affordances such as “Jump to Definition” or “Open Quickly” work equally well with Swift, and even Objective-C header definitions can be shown in Swift syntax.
Please refer the following links for more detail:
https://itunes.apple.com/us/book/swift-programming-language/id881256329?mt=11
https://developer.apple.com/xcode/
It’s Xcode 6+. And you have to save the Swift code in a .swift file, not .m.
You need xcode 6.1 Minimum for osx apps. If you try to use the orginial version of xcode 6, you will only be able to use the playground and create osx apps.
I've decided to learn c++ and try to make a game with SDL framework. The problem is that I don't know how to use SDL together with Xcode 4.3, since I can't use it like a template, as seen in other guides. Would be great if someone could help me get SDL to work with Xcode 4.3.
EDIT:
I try add SDL to Xcode project following http://meandmark.com/blog/2012/01/using-sdl-with-xcode-4/
When I try to compile I get this error:
The following article should help you:
Using SDL with Xcode 4
It took a quite long time until I got SDL and Xcode running. So, don't care. :-)
I uploaded here a simple SDL template for Xcode 4.5 and Mac OS X 10.7 and 10.8 (also using OpenGL 3.2 Core Profile possible). Step by Step instructions:
Download SDL (at the moment version 1.2.15)
Open the downloaded .dmg file
copy the SDL.framework into /Library/Frameworks/
Done. You can use the Xcode template (you should see a red area):
