iOS 26 will introduce a long-awaited feature for Apple Messages in its operating system.
In an exciting development for cross-platform messaging security, leaked code from Apple's upcoming iOS 26 suggests that the tech giant is internally testing end-to-end encryption (E2EE) for RCS messaging. The encryption approach seems to align with Message Layer Security (MLS) encryption, a recent GSMA standard supported by Google Messages.
The code, discovered by Android Authority, includes the string "GisRCSEncryptionEnabled," indicating internal testing of RCS encryption. However, it's important to note that there is no official confirmation that this feature will be fully implemented and available to users in the public release of iOS 26. Apple has previously stated that E2EE for RCS would come in "future software updates" without specifying a timeline.
If implemented, this could mark a significant step towards securing RCS chats between iPhone and Android devices, addressing a long-standing security flaw. The implementation of RCS encryption could make cross-platform texting safer for millions of users worldwide.
Moreover, iOS 26 might bring features akin to WhatsApp to Apple's Messages app. The beta version of the operating system includes filters for scheduled messages and unread messages, as well as the ability to filter messages by draft status. These filters only appear if there is a relevant message to filter.
However, it's essential to approach these developments with caution. Some sources caution that key features of RCS (e.g., group icons, mentions) might not be included initially. Furthermore, there's no guarantee that iOS 26 will implement RCS encryption.
For those eager to try out the iOS 26 public beta, further information about how to download and install it can be found in separate articles. It's crucial to remember that beta software can be unstable and may contain bugs, so it's recommended to back up your device before installing the beta version.
The GSMA announced in March 2025 that end-to-end encryption would be added to RCS. With Apple's recent developments, it seems that the industry is moving towards a more secure future for cross-platform messaging. Stay tuned for more updates on this exciting development.
