Xcode的“工具链”设置在哪里?

I upgraded my project from Swift 2.2 to 2.3 (Xcode 7 to 8), and committed everything on one Mac. When I pulled from git on my other Mac, and built, I get:

我将我的项目从Swift 2.2升级到2.3 (Xcode 7升级到8)，并在一个Mac上提交所有内容。

Warning: target specifies SWIFT_VERSION = '2.3', but it is overridden by TOOLCHAINS = 'com.apple.dt.toolchain.XcodeDefault'

I can't find anything called "TOOLCHAINS" in any file. What's this warning mean?

我在任何文件中都找不到所谓的“工具链”。这个警告是什么意思?

I had the same warning and i could solve the problem by cleaning the build folder (alt+shift+cmd+K)

我有同样的警告，我可以通过清理构建文件夹来解决这个问题(alt+shift+cmd+K)

#2

I see you have solved the problem by upgrading to Swift 3.0.

我看到你已经通过升级到Swift 3.0解决了这个问题。

I encountered the same problem, and did some research in this. When building within Xcode, make sure you have the setting " Project > Build Settings > Use Legacy Swift Language Version" set to "Yes"

我遇到了同样的问题，为此做了一些研究。在Xcode中构建时，请确保设置为“Project > Build Settings >使用遗留的Swift语言版本”，设置为“Yes”

For those who are using xcrun or xcodebuild tools, I managed to solve it by using an extra option 'toolchain'

对于那些使用xcrun或xcodebuild工具的人，我通过使用一个额外的选项“工具链”来解决它

xcrun --toolchain "com.apple.dt.toolchain.Swift_2_3"
xcodebuild -toolchain "com.apple.dt.toolchain.Swift_2_3"

The identifier "com.apple.dt.toolchain.Swift_2_3" can be found at:

“com.apple.dt.toolchain的标识符。Swift_2_3"可在:

/Applications/Xcode-beta.app/Contents/Developer/Toolchains/Swift_2.3.xctoolchain/ToolchainInfo.plist

Hope this helps for those who are developing in Swift 2.3.

希望这对正在开发的Swift 2.3有所帮助。

Toolchains is not explicitly called out as it was in the prior builds. However, it is still there in the Locations -> Command Line Tools portion of the Xcode Preferences menu

工具链并不像之前的构建那样被显式地调用。然而，它仍然存在于位置->命令行工具部分的Xcode首选项菜单。

Choosing Xcode 8 resolved the issue for me.

选择Xcode 8为我解决了这个问题。

#4

Toolchains are set under the Xcode menu then Toolchains. It should be set to Xcode 8. There is also a build setting in Xcode 8 called "Use legacy swift version" that should be set to YES so that you use Swift 2.3 instead of 3.

工具链设置在Xcode菜单下，然后是工具链。它应该设置为Xcode 8。Xcode 8中还有一个名为“使用遗留swift版本”的构建设置，应该设置为YES，以便使用swift 2.3而不是3。

#5

If you don't have "Toolchain" option under XCode menu, you need to download and install a snapshot or release first.

如果在XCode菜单下没有“工具链”选项，您需要先下载并安装快照或发布。
