According to Bloomberg’s Mark Gurman, Apple has ambitious plans for iOS 18.

In a Power On newsletter Q&A, Gurman said iOS 18 could be the biggest software update in iPhone history.

Gurman said he planned to share more details about iOS 18 features and future changes. Two possible additions were already known.

RCS

In November 2023, Apple announced plans to support the cross-platform RCS messaging standard in Messages from 2024, making it a likely iOS 18 feature.

RCS support is expected to improve the default messaging experience between iPhone and Android devices in the following ways:

Photos and videos with higher resolution

Audio Message

Typing indicator

Read receipts

Wi-Fi messaging between iPhone and Android devices

Improved group chats, including conversations between iPhone and Android users.

Better encryption than text messages.

A smarter Siri

Gurman expects generative AI in iOS 18 to improve how Siri and Messages answer questions and complete sentences. He said Apple had also explored generative AI features for Apple Music, Pages, Keynote and Xcode.
