# initialize(repeating:) Initializes every element in this buffer slice’s memory to a copy of the given value. ``` func initialize(repeating repeatedValue: Element) where Base == UnsafeMutableBufferPointer ``` ## Parameters `repeatedValue` The value with which to initialize this buffer slice’s memory. ## Discussion The destination memory must be uninitialized or the buffer’s `Element` must be a trivial type. After a call to `initialize(repeating:)`, the entire region of memory referenced by this buffer slice is initialized. --- Copyright © 2026 Apple Inc.
