# setDefaultPlaceholder(_:for:with:)

Sets `placeholder` as the default placeholder for the `binding`, when a key value coding compliant property of an instance of the receiving class returns the value specified by `marker`, and no other placeholder has been specified.

```
class func setDefaultPlaceholder(_ placeholder: Any?, for marker: Any?, with binding: NSBindingName)
```

## Discussion

The `marker` can be `nil` or one of the constants described in <doc://com.apple.documentation/documentation/AppKit/selection-markers>.
