What do the arrows in the navigator pane on Xcode indicate?
提问by Dimitrie-Toma Furdui
In earlier versions of Xcode the source control tool would indicate that you have modified a file by showing a bold 'M' to the right of the file name.
在早期版本的 Xcode 中，源代码控制工具会通过在文件名右侧显示粗体“M”来指示您已修改文件。
In Xcode 9 I noticed that some of my files now show either an upward or upward facing arrow. What do they indicate?
在 Xcode 9 中，我注意到我的一些文件现在显示向上或向上的箭头。它们说明什么？

The arrows that sometimes appear to the right of a file in the navigator is indicating whether you have any files that has not yet been pushed to your remote branch or if you have changes for that file to be pulled from a remote.
有时出现在导航器中文件右侧的箭头表示您是否有任何尚未推送到远程分支的文件，或者您是否对该文件进行了更改以从远程拉取。
The upward pointing arrow indicates you have local changes for that file that have not been pushed to your remote repository.
向上的箭头表示您对该文件的本地更改尚未推送到您的远程存储库。
The downward pointing arrow indicates you have remote changes to that file that you have not fetched yet.
向下的箭头表示您对该文件进行了远程更改，但尚未获取。
The arrows looks like this in Xcode 9.
箭头在 Xcode 9 中看起来像这样。

I'm assuming you mean the arrows on the left of the text. The down arrow means it is displaying all its contents below. Click it to collapse its contents and it turns to a right arrow. The Mstands for modified since its last source control commit and if you encounter an A, it stands for added.
我假设您指的是文本左侧的箭头。向下箭头表示它正在显示下面的所有内容。单击它以折叠其内容，它会变成一个向右箭头。该M自上次源控制修改代表承诺，如果你遇到一个A，它代表补充说。
