Changelog for Swift SDK

Fixed

Add a wrapper around the reconnecting method for KMP (internal use).

Fixed

Add missing heartbeat call when changing channels or channel groups.

Added

The encryptStream(from:) convenience method is designed to encrypt a local file. It eliminates the need for the caller to provide an InputStream and its content length - these are handled internally. You only need to pass a local file URL.

Added

The encrypt(stream:contentLength:) method in CryptoModule now returns an EncryptedStreamResult containing both the encrypted stream and its total content length.
The new decryptStream(from:to:) method in CryptoModule simplifies file decryption by automatically handling low-level details, in contrast to decrypt(stream:contentLength:to:). Instead of manually creating an InputStream and specifying the content length, you now only need to provide the source and destination URLs.

Fixed

Include endpoint error message in PubNubError's details property.
Defer computing the textual representation of EventEngine's current and previous states until needed.

Added

Add OSLogWriter as the recommended LogWriter to use.
Refine LogWriter protocol signature to support built-in Logger from the os framework.
Enhance object descriptions with CustomStringConvertible.
Add explanatory documentation for debug-level logging messages.
