# `GSLayer associatedFontMaster`

*Instance Method*

The master that supplies master-specific values for the layer.

## Declaration

```swift
func associatedFontMaster() -> GSFontMaster?
```

```objc
- (GSFontMaster *) associatedFontMaster;
```

```python
associatedFontMaster() -> GSFontMaster
```

## Discussion

For an Intermediate layer, this can be a master interpolated at the layer coordinates. Returns `nil` when the layer is detached or its associated master cannot be resolved.
