Now, another core technology area we've invested in is source control.

另外一项我们大力投入的核心技术就是源码控制。

The new source control navigator allows me to explore a project.

新的源码控制导航允许我浏览项目。

And this is just the start of some of the amazing new source control work flows we have for you.

这只是我们为你们准备的一系列特别出色的新源码控制工作流的一个开始。

Hello, I'm going to show you today some of the great new ways to work with source control in Xcode.

大家好，我今天要展示一些在 Xcode 里使用源码控制的一些很棒的新方式。

In the new source control navigator, I'll use the Context menu to make a new branch for " master."

在新的源码控制导航中，我要使用 Context 菜单制作一个分支，名字叫“master”。

Now, I can also seamlessly use source control while I'm making changes, and I have another project that needs a little work that I'll open now.

现在，我还可以在改动的同时无缝使用源码控制，我还有另一个需要稍作修改的项目，现在我把它打开。

Back in the source control navigator, I'll select the destination branch and again use the Context menu to merge in the changes for my working branch.

回到源码控制导航上面，我会选择目的分支，并再次使用 Context 菜单来融入我的工作分支的更改。

Fortunately, source control software keeps track of all changes, and if a bug is found, the whole code, or just a piece, can be rolled back to an earlier, stable version.

幸运的是，源代码控制软件会跟踪所有更改，如果发现错误，可以将整个代码或只是一段代码回滚到较早的稳定版本。
