According to insiders, Apple plans to launch the iOS 18.4 system in April 2025. Although the beta version of iOS 18.4 has not yet been released, there are already some expectations about the upgrade content of this system.

Siri's functionality is set to see significant enhancements. Apple intends to introduce three major upgrades to Siri via the iOS 18.4 system in the spring, propelling it into a new era of Apple intelligence. These three upgrades encompass personal context awareness, screen perception, and application access capabilities. With these improvements, Siri will be able to better understand users and their surroundings, performing more actions for them.

Apple's intelligent features will support additional languages. When iOS 18.2 was launched, Apple announced that it would add support for more languages in its intelligent functions starting from April 2025. Although Apple did not specify exactly which languages would be supported or when at the time, it revealed a list of languages planned for support throughout 2025. It is understood that a software update in April will broaden language support, with more languages being added gradually over the year. These include Chinese, Indian English, Singaporean English, French, German, Italian, Japanese, Korean, Portuguese, Spanish, Vietnamese, among others.

Moreover, iOS 18.4 will introduce a new batch of emojis. In recent years, Apple has added new emoji support in its spring iOS versions, a trend expected to continue this year. The Unicode Consortium has already published the latest batch of emojis, and Apple just needs to incorporate them into the system. This year's new emojis include fingerprints, faces with eye bags, harps, root vegetables, leafless trees, splashes, and shovels. Here is a preview of these seven upcoming new emojis.
