Apple has released iOS 18.6 Beta 3 to developers on July 14, 2025, marking the likely final testing phase before its anticipated public release in late July.
This maintenance update focuses primarily on EU regulatory compliance under the Digital Markets Act (DMA), alongside critical stability improvements, with no major new consumer features introduced.
Release Information
The beta (build 22G5073B) is available through the Developer Program via Settings > General > Software Update, with a modest download size of ~420MB.
Historical patterns suggest a public release between July 21-30, 2025, following Apple's typical mid-summer schedule for "point-six" updates.
Notably, this update includes modem firmware version 1.70.02, addressing connectivity issues reported in earlier betas.
Key Updates
EU Digital Markets Act Compliance
- Developers can now promote alternative purchasing options outside the App Store, including links to third-party marketplaces and websites.
- To enhance installation efficiency, Apple has minimized warnings and reduced friction for EU users installing apps from alternative sources.
- Starting in 2026, Core Technology Commission fees will replace existing fee structures.

Apple Car Keys
Apple continues to refine its digital key experience with the latest iOS 18.6 Beta 3, introducing version 4.0 of Apple Car Keys.
Developed in collaboration with partners like BMW, this update aims to enhance functionality and seamless integration.
Accessible through the Wallet app, Apple Car Keys allows users to lock, unlock, and control vehicle features like climate and trunk with minimal power consumption compared to other apps, such as Tesla's.
This beta promises improved efficiency and potential new features, further streamlining the user experience for compatible vehicles.
Performance and Bug Fixes
Early testing indicates significantly improved stability compared to iOS 18.5, with:
- Smoother UI Performance: Elimination of micro-stutters in system animations
- Thermal Management: Device temperatures consistently below 100°F during normal use
- Bug Resolutions: Fixed HealthKit accessibility issue when device reaches power-off screen
- Ongoing Issues: Wallpaper desaturation in notification center remains unresolved

Editor's Comments
iOS 18.6 represents Apple's strategic shift toward regulatory compliance rather than feature innovation.
The DMA-mandated changes could fundamentally alter app distribution economics in Europe, though they introduce new security challenges Apple is mitigating through notarization requirements.
With iOS 26 expected to debut major Siri enhancements in September, this update serves as a crucial stability bridge - particularly welcome after the problematic iOS 18.5 release.
Developers should prepare for the new commission structure, while EU users will soon experience a more open (though potentially riskier) app ecosystem.
