It is possible with Xcode 10+, see the wwdc2018 presentation of the functionality.
Xcode 10+ 是可能的，请参阅wwdc2018 功能介绍。

I'm not sure how helpful this is to you, but if you want to change a variable name, you can click it, hover over it until the triangle dropdown button appears, click it and select Edit All in Scope.
我不确定这对您有多大帮助，但是如果您想更改变量名称，您可以单击它，将鼠标悬停在它上面直到出现三角形下拉按钮，单击它并选择“编辑范围内的全部”。
This allows you to change all instances of that variable name.
这允许您更改该变量名称的所有实例。

I had this same question a few weeks ago, if you use the Option Key you can use column select and edit multiple lines like in your picture. Where the confusion comes in is it is used for multiple things. If you click the option key over a variable or text it shows a question mark and shows information about what you click on. However, if you hold the option key while before the line or not over text it shows up as a plus symbol and you can drag and select multiple lines and edit them at the same time.
几周前我遇到了同样的问题，如果您使用 Option Key，您可以使用列选择并编辑图片中的多行。混淆之处在于它用于多种用途。如果您单击变量或文本上的选项键，它会显示一个问号并显示有关您单击内容的信息。但是，如果您在行前或不在文本上按住选项键，它会显示为加号，您可以拖动并选择多行并同时编辑它们。
