Cook has already said that iOS 10 is immensely powerful. It is the soul of iPhone and other similar products. This robust OS is advanced, developers work seamlessly on it. As the incredible numbers are making them humble, Apple realized that iOS needs improved features.

Older apps can never yield impressive results, they need replacements. Alert messages are coming out as notifications; 32-bit versions are much slower. The system will show solid performance, if some steps are followed. Apple’s OS has some robust figures, the usage is substantially more. They have to beat Android every year, apps must run very fast.

By issuing this danger alert, Apple is generating awareness. When developers incorporate the changes, users will blindly follow it. Apple has a fixed framework for apps; they will bring everything under that. For users, iPhone’s performance is everything; they never want the software to do that. App creators will become angry, but Apple has no choice now. One single app can make the entire interface lag; we never see that in iPhones. App optimization is a point they are stressing on, the results will be seen later. A better iOS will create loyal users, Apple already witnessed that. Big apps already listened to Apple, they follow recommended guidelines.

In 2013, the first phase of optimized apps was launched. Developers got the guidelines beforehand; they opted for 64-bit versions. Sales can fluctuate, numbers can vary; but customer service can’t go down ever. If they lose that position, it will be the biggest loss. Apple is only surviving, because of loyalty. This is Apple’s way of communicating with the ecosystem, unique and powerful. App Store will not contain backdated apps; the cleaning process was really needed. Their function has to be different too, iOS is changing rapidly. Years and years of dominations has taught Cook many things, he knows the business.
