The allocator object that created the buffer.
- iOS 9.0+
- macOS 10.11+
- tvOS 9.0+
- Model I/O
Certain operations on the MDLMesh object that owns this buffer—for example, generating new vertex attributes with methods such as
add, or changing the format and layout of vertex data by assigning a new value to the
vertex property—may require reallocation of buffer memory. When you perform such operations, Model I/O uses the same allocator that was used to create the buffer.
