clang-format failed.
Could not find front document.

First, I want to thank Sean Parent.
Help me use it.
So, I followed everything to install it, by making a folder 'xcode' in my home directory, and then it has 'tools' directory. I made a file called '.clang-format' which has this as its content:

UseTab: Never
IndentWidth: 4
BreakBeforeBraces: Allman
AllowShortIfStatementsOnASingleLine: false
IndentCaseLabels: false
ColumnLimit: 0

Then, since I didn't change the shortcut for cmd+c or cmd+v, I didn't edit any other file.
Then... do I have to select all contents of the file to format it? Is it automatically format the file whenever I save the file? Would you clarify how to use it? Do I have to restart xcode after setting it? It looks like nothing works...

Hi, I'm running into the issue that when the behavior runs, I'm getting some weird insertions:

clang-format version 7.0.0
XCode version 9.2

(I've used my configs in Visual Studio Code for quite some time successfully.)

To reproduce this issue, you can try to reformat the following code snippet:

  if (![helper verify:faceInfo] || ![helper insideScreen:faceInfo]) {
    [self updateFaceInfoOnUIThread:faceInfo];
    [self updateTrackingLabelOnUIThread:@"检测不到人脸"];
    return nil;
  }

In my xcode(10.3 on Mojave 10.14.6), the chinese string "检测不到人脸", will turn into "妫ü娴�涓���颁汉���" after reformatted, namely a garbled string.

Could you please help?
