Xcode - 源文件中的字符无效（将“"”替换为“"”） [英] Xcode - Invalid character in source file (Replace " " with " ")

问题描述

我对Xcode（Swift）有疑问。有时当我写一个if语句。这样的事情：

I have a question about Xcode (Swift). Sometimes when I write an if statement. Something like this:

if(a == 2){
//do Sth
} else {
//do Sth
}

Xcode给我一个错误：源文件中的字符无效
我知道这不是什么大问题并通过点击修复它来修复但我希望
知道是什么问题。这对我来说没有意义......

Xcode throws me an error: "Invalid character in source file" I know it is no big deal and fixed by clicking on "Fix-it" but I want to know what is the problem. That doesn't make sense to me...

我的Xcode在7.2上，我正在使用Swift - 我不知道这是否只是一个Swift问题。

My Xcode is on 7.2 and I am using Swift - I don't know if this is just a Swift problem.

推荐答案

我是有这个问题。我解决它的方法是1）将您拥有的任何内容复制到Sublime Text或其他代码编辑器中并查看（您可能需要启用查看隐藏字符）。我的DC2中有一个代码，它是某种ASCII控制字符。对我来说，这是因为我把操场放到了手动执行中并绑定了一个键盘快捷键，它似乎每次使用快捷键执行时都会输入该控制字符。我只是更改了快捷方式并删除了ASCII字符，因为我能够在Sublime Text中看到它们。 （关于从左到右模式的OP评论中的链接没有任何意义，对我来说没有用。）

I was having this problem. The way I solved it is by 1) copying whatever you have into Sublime Text or another code editor and having a look (you may need to enable viewing hidden characters). Mine had a code in there DC2 which is some sort of ASCII control character. For me it was caused by the fact that I had put the playground into manual execute and bound a keyboard shortcut to it that seemed to be entering that control character every time I executed it using the shortcut. I just changed the shortcut and removed the ASCII characters as I was able to see them in Sublime Text. (The link in the comments to the OP concerning left to right mode made no sense and didn't work for me.)
