# canBeConverted(to:) Returns a Boolean value that indicates whether the receiver can be converted to a given encoding without loss of information. ``` func canBeConverted(to encoding: UInt) -> Bool ``` ## Parameters `encoding` A string encoding. For possible values, see [`NSStringEncoding`](/documentation/Foundation/NSStringEncoding). ## Return Value if the receiver can be converted to `encoding` without loss of information. Returns if characters would have to be changed or deleted in the process of changing encodings. ## Discussion If you plan to actually convert a string, the `dataUsingEncoding:...` methods return `nil` on failure, so you can avoid the overhead of invoking this method yourself by simply trying to convert the string. --- Copyright © 2026 Apple Inc.
