If you live in the European Union, iOS 17.4 is a massive upgrade. Apple began beta-testing the update on January 25 and outlined many of the changes that affect the apps and App Store experience on the iPhone. The primary aim of this release is to comply with the Digital Markets Act in the EU, which has a deadline of March 6. Apple has released the update just before that date.
There are some 600 new APIs, expanded app analytics, functionality for alternative browser engines, access to NFC for mobile payment systems, and options for processing app payments and distributing iOS apps outside the App Store. Apple has a new payment and commissions structure for apps released outside the App Store or who use payment systems other than Apple’s, which some developers have taken exception to.
Updated March 5: Everyone can now download and install the final release of iOS 17.4.
iOS 17.4: Big new app distribution changes for the EU
An Apple press release goes over all the changes meant for the EU and they are major, bringing alternative app stores and payments, along with a host of other changes, including:
New options for distributing iOS apps from alternative app marketplaces: New APIs and tools that enable developers to offer their iOS apps for download from alternative app marketplaces.
New framework and APIs for creating alternative app marketplaces: Marketplace developers can install apps and manage updates on behalf of other developers from their dedicated marketplace app.
New frameworks and APIs for alternative browser engines: Developers can use browser engines, other than WebKit, for browser apps and apps with in-app browsing experiences.
Interoperability request form: Developers can submit additional requests for interoperability with iPhone and iOS hardware and software features.
There are new app safety features as well, meant to mitigate the risks Apple says are inherent in getting apps from places other than the App Store:
Notarization for iOS apps: A baseline review that applies to all apps, regardless of their distribution channel, focused on platform integrity and protecting users. Notarization involves a combination of automated checks and human review.
App installation sheets: Use information from the Notarization process to provide at-a-glance descriptions of apps and their functionality before download, including the developer, screenshots, and other essential information.
Authorization for marketplace developers: Ensures marketplace developers commit to ongoing requirements that help protect users and developers.
Additional malware protections: Prevents iOS apps from launching if they’re found to contain malware after being installed on a user’s device.
iOS 17.4: General new features
Other features in the beta for U.S. users and the rest of the world include:
Apple Cash virtual card numbers: iOS 17.4 makes it easier to spend money from your Apple Cash account by assigning a virtual card number, which can be used as a prepaid debit card when Apple Pay isn’t available.
New emojis: A number of new emojis, from the Emoji 15.1 standard, are present in iOS 17.4.
Apple Music “Home” tab: The tab formerly labeled “Listen Now” has been renamed “Home.”
Stolen Device Protection: Users can now choose to always require a delay when changing security settings, not just when away from familiar locations.
Podcast transcripts: The Podcast app will provide transcripts in English, French, German, and Spanish for podcast episodes. They can be auto-generated, or podcast publishers can supply their own.
Stopwatch live activity: There’s now a Live Activity when you have a stopwatch running.
CarPlay instrument cluster experience: In supported vehicles, CarPlay will display information about upcoming maneuvers. Users will be able to swap between the main and instrument cluster screens by tapping the map configuration button on the upper right of the Maps app main screen.
Battery settings UI tweaks: For the iPhone 15 series, Apple is including a “Battery Health” listing that displays the battery’s condition. For example, if the battery has no issues, the listing displays “Normal.” Tapping the Battery Health listing shows a section that displays the Maximum Capacity, Cycle Count, Manufacture Date, and First Use.
iMessage post-quantum cryptography: Apple has announced “the most significant cryptographic security upgrade in iMessage history” using PQ3, a groundbreaking post-quantum cryptographic protocol that advances the state of the art of end-to-end secure messaging.
iOS 17.4: Security updates
The release of iOS 17.4 contains several security updates. Apple has listed four of them affecting Accessibility, Kernel, RTKit, and Safari Private Browsing, but says additional CVE entries are coming soon, likely when macOS 14.4 arrives next week. The Kernel and RTKit entry both say Apple is aware of a report that this issue may have been exploited.
