Apple previews iOS 12

Apple previewed iOS 12 today, and two features stand out to me as exciting and interesting. First, a focus on performance for the many, many people using older iPhones and iPads.

The company said it is putting a particular focus on ensuring the update works smoothly on older devices. To give a point of reference, Craig Federighi, Apple's senior vice president of software engineering, said iOS 12 will launch apps up to 40% faster and bring up the keyboard up to 50% faster on an iPhone 6 Plus. Federighi said the update will make a compatible phone "instantly ramp up performance to its highest state" when it recognizes that it needs a performance boost - such as when you're loading an app - then more quickly bring it down to help preserve battery life.
