# decodeBytes(forKey:minimumLength:) Decode bytes from the decoder for a given key. The length of the bytes must be greater than or equal to the `length` parameter. If the result exists, but is of insufficient length, then the decoder uses `failWithError` to fail the entire decode operation. The result of that is configurable on a per-NSCoder basis using `NSDecodingFailurePolicy`. ``` func decodeBytes(forKey key: String, minimumLength length: Int) -> UnsafePointer? ``` --- Copyright © 2026 Apple Inc.
