Hello, guys. Faced with this problem. Swift-format error shown, if I have the line break between the `error` word in the function parameters.

swift-format shows an error:

```swift
   func test(
        error: Error
    ) {
        print("test \(error)")
    }

```

swift-format doesn't show an error

```swift
    func test(error: Error) {
        print("test \(error)")
    }

```

swift-format version: 0.50500.0 Thanks.

What is the error you are referring to?

swift-format seems to be printing out every single file to the console, and Xcode interprets any line starting with `error: ` as an error. That’s kind of funny and unfortunate.

What is the contents of your script phase for running swift format?

> Xcode interprets any line starting with `error: ` as an error.

Same thoughts.

```swift
if which swift-format >/dev/null; then
    swift-format format -r ${PROJECT_DIR} --configuration .swift-format.json
    swift-format lint -r ${PROJECT_DIR} --configuration .swift-format.json
else
    echo "warning: swift-format not installed"
fi
```

Make sure that you use the [`-i` or `--in-place` flag](https://github.com/apple/swift-format#formatting) on the `format` command to write the output back to the original file, otherwise it gets written to standard output.
