Apple has announced that the latest iOS 12 Gold Master will be launched before the new set of iPhones are launched and this will take place on the 12th of September, 2018.
iOS 12 Gold Master is the final version of the iOS software release that has been designed solely for experts in technological affairs. The iOS 12 Gold Master will boost the performance capabilities of iPhone devices like the iPhone 5s and so on.
Although the iPhone 5s runs on iOS 11, Apple has promised that even older Apple devices will also receive the iOS update. The Group Face-time calling feature wouldn’t be available on this particular OS version as it will be released in a version after the iOS 12, iOS 12.X.
