# assumingMemoryBound(to:) Returns a typed buffer to the memory referenced by this buffer, assuming that the memory is already bound to the specified type. ``` func assumingMemoryBound(to: T.Type) -> UnsafeBufferPointer where T : ~Copyable ``` ## Parameters `to` The type `T` that the memory has already been bound to. ## Return Value A typed pointer to the same memory as this raw pointer. ## Discussion Use this method when you have a raw buffer to memory that has already been bound to the specified type. The memory starting at this pointer must be bound to the type `T`. Accessing memory through the returned pointer is undefined if the memory has not been bound to `T`. To bind memory to `T`, use `bindMemory(to:capacity:)` instead of this method. > Note: The buffer’s base address must match the > alignment of `T` (as reported by `MemoryLayout.alignment`). > That is, `Int(bitPattern: self.baseAddress) % MemoryLayout.alignment` > must equal zero. --- Copyright © 2026 Apple Inc.
