No platform is more or more crucial in the eyes of Apple or its consumers than the iPhone. Consequently, no OS upgrade is any more crucial than iOS in the mobile app development industry. Apple announced its annual major operating system upgrades in its WWDC keynote speech on June 6. After a resounding reception for iOS 15 in 2021, iOS 16 was expected to bring various new features. It did not let us down. The best part about the iOS 16 features is that they'll not just benefit those who are looking to purchase the next iPhone 14, but they can also be used on older iPhones. It will be a while until Mid-September when it will launch. However, the new features will change your device for the better. The new features weren't limited to the phone, however. The new features extend from the iOS to Smart Home and the car as an amazing new-generation Car Play, coming in 2023.
