Privacy has been a renewed focus with Apple’s next operating system update. One new feature in iOS 13 that seems centered on user privacy could have sweeping consequences for messaging and online call apps. From a report: In iOS 13, Apple will not allow apps to run voice over Internet protocol (VoIP) in the background when the programs are not actively in use. Many apps that offer VoIP services currently run in the background, and they will need to be rewritten to adjust to Apple’s upcoming rules. The change is slated to roll out when iOS 13 is released in September. However, app developers will get a grace period, and they have until April 2020 to comply. VoIP services ostensibly stay running in the background so they can connect calls quickly, but they also let those apps collect information about what users are doing on their devices. Restricting the programs that can simply be open at any time on its mobile hardware fits the narrative Apple is crafting about being a trusted place for customer privacy in an increasingly untrustworthy industry.
