# alignment(ofValue:) Returns the default memory alignment of `T`. ``` static func alignment(ofValue value: borrowing T) -> Int ``` ## Parameters `value` A value representative of the type to describe. ## Return Value The default memory alignment, in bytes, of the given value’s type. This value is always positive. ## Discussion Use a type’s alignment when allocating memory using an unsafe pointer. When you have a type instead of an instance, use the `MemoryLayout.stride` static property instead. ``` let x: Int = 100 // Finding the alignment of a value's type let s = MemoryLayout.alignment(ofValue: x) // s == 8 // Finding the alignment of a type directly let t = MemoryLayout.alignment // t == 8 ``` --- Copyright © 2026 Apple Inc.
