Apple released the second developer betas of iOS 17.4 and iPadOS 17.4, two weeks after the first betas.

Registered developers can opt in under Settings → Software Update → Beta Updates by selecting the iOS 17 or iPadOS 17 developer beta.

iOS 17.4 changes how the App Store and apps operate in the EU, enabling alternative app marketplaces, alternative payment systems, third-party browser engines and NFC access for banks and third-party payment providers. These features are limited to the EU.

With iOS 17.4, Apple will allow cloud gaming apps such as Xbox Cloud Gaming and NVIDIA GeForce Now.

iOS 17.4 also adds emoji, podcast transcripts and SharePlay support for HomePod, among other changes.
