Apple this week announced iOS 16, which brings new features such as a redesigned lock screen with widgets, expanded Focus Mode, iMessage improvements, passkeys, and more. In addition, iOS 16 comes with multiple new APIs, including one that enables walkie-talkie capabilities for third-party apps. The new API is called “Push to Talk,” and it basically lets developers add a walkie-talkie to their iOS apps.
