# `GSFont.features`

*Instance Property*

Layout features used when compiling OpenType feature code.

## Declaration

```swift
var features: [GSFeature] { get set }
```

```objc
@property (nonatomic, strong) NSArray<GSFeature *> * features;
```

[See also `features` in the Python API](https://docu.glyphsapp.com/#GSFont.features)

```python
pyobjc_instanceMethods.features() -> list[GSFeature]
pyobjc_instanceMethods.setFeatures_(features: list[GSFeature])
```

## Discussion

The order of the features is significant for feature generation and export.
