使用 Subversion 绝对不会出错.

You can't really go wrong with using Subversion.

如果像我一样，您不太喜欢 Xcode 的 SVN 集成，您可以随时选择使用命令行工具，或者几个 GUI 应用程序之一，如 Versions、CornerStone 或 SvnX.这些工具中的大多数都可以很好地协同工作，因此您不一定会依赖于您开始使用的工具.

If, like me, you don't like Xcode's SVN integration too much you can always choose to use the command-line tools, or one of the several GUI apps like Versions, CornerStone or SvnX. Most of these tools work together pretty well, so you're not necessarily tied in to the tool you start out with.

我个人使用 Versions 完成大部分工作，并且每隔一段时间使用命令行工具处理相同的工作副本.

I personally do most of my work with Versions, and use the command-line tools with the same working copies every once in a while.

如果在有人围绕它创建一个好的 GUI 应用程序之前，你习惯于只使用命令行工具，那么 git 也是一个非常可行的选择.

If you're comfortable working with command-line tools exclusively until someone creates a good GUI app around it, git is a pretty viable option too.

披露:我是从事版本工作的人之一，所以我可能有点偏见;)

disclosure: I'm one of the people who work on Versions, so I might be slightly biased ;)
