# setTileSamplerState(_:index:)

Assigns a sampler state to an entry in the tile shader argument table.

```
func setTileSamplerState(_ sampler: (any MTLSamplerState)?, index: Int)
```

## Parameters

`sampler`

An [`MTLSamplerState`](/documentation/Metal/MTLSamplerState) instance the command assigns to an entry in the tile shader argument table for sampler states.

`index`

An integer that represents the entry in the tile shader argument table for sampler states that stores a record of `sampler`.
