```

## Discussion

Discussion The value of this property needs to be between 1 and 2048, inclusive. The default value is 1. This value is 1 if the texture type is not an array. This value can be between 1 and 2048 if the texture type is one of the following array types: MTLTextureType.type1DArray MTLTextureType.type2DArray MTLTextureType.type2DMultisampleArray MTLTextureType.typeCubeArray
