# loadUnaligned(fromByteOffset:as:) Returns a new instance of the given type, constructed from the raw memory at the specified offset. ``` func loadUnaligned(fromByteOffset offset: Int = 0, as type: T.Type) -> T where T : BitwiseCopyable, T : ~Escapable ``` ## Parameters `offset` The offset from this pointer, in bytes. `offset` must be nonnegative. The default is zero. `type` The type of the instance to create. ## Return Value A new instance of type `T`, read from the raw bytes at `offset`. The returned instance isn’t associated with the value in the range of memory referenced by this pointer. ## Discussion This function only supports loading trivial types, and will trap if this precondition is not met. A trivial type does not contain any reference-counted property within its in-memory representation. The memory at this pointer plus `offset` must be laid out identically to the in-memory representation of `T`. > Note: A trivial type can be copied with just a bit-for-bit copy without > any indirection or reference-counting operations. Generally, native > Swift types that do not contain strong or weak references or other > forms of indirection are trivial, as are imported C structs and enums. --- Copyright © 2026 Apple Inc.
