Apple this week said that it plans to add support for end-to-end encrypted RCS messages to the Messages app in future iOS, iPadOS, macOS, and watchOS software updates, and that news actually has some additional implications.
As noted by 9to5Mac‘s Michael Burkhardt, Apple has indirectly confirmed that it will be adopting the RCS Universal Profile 3.0 specification, which includes not only end-to-end encryption, but also several other iMessage-like enhancements that were originally introduced in version 2.7 of the specification. iOS 18 supports RCS Universal Profile 2.4.
Here are five new capabilities to expect for RCS conversations:
- End-to-end encryption, which will prevent Apple and any other third party from being able to read messages and attachments while they are being sent between devices.
- In-line replies
- Edit messages
- Unsend messages
- Full-fledged Tapback support for RCS messages, ensuring they always work
iMessage conversations with blue bubbles have supported end-to-end encryption by default since iOS 5. In addition, iMessage has supported in-line replies since iOS 14, while the options to edit and unsend iMessages were introduced with iOS 16.
Apple has not indicated which iOS version will upgrade RCS, but iOS 19 or a follow-up update like iOS 19.1 or iOS 19.2 seems like a safe bet.
