4Important News from Apple - EL CAPITAIN

SPOTLIGHT as a Search Engine..

The new search systemallows users to resize and move the Spotlight window, which presents new types of content.

Sports scores and other Siri data will be supported, and natural language search allows users to track down mail messages and documents easily. The search upgrades are also available in apps like Mail and Finder.

METAL for Mac..

50% improvements in rendering with 40% less CPU processing power required for graphics. Metal on OS X El Capitan offers better battery life and improved graphics performance for both games and professional apps.

SAFARIA new pinned feature enables users to keep websites listed at the top of Safari, similar to a bookmarks bar. The browser also gains a universal mute feature that allows users to mute a website that is playing music, even with several tabs open.

Call out your cursor.

Important News from Apple IOS9 6

SEARCH (Siri Suggestions)App HistoryContent indexingWeb markup

SIRISiri can do a lot more in iOS 9 with contextual awareness. If you ask Siri to "Remind me to do this" when looking at a request you've received in the Messages app, Siri will understand what you mean by "this" and will add the event.SPLITVIEW for iPad

Safari View ControllerCreated with the goal to let developers stop writing miniature web browsers, Safari View Controller enables apps to delegate the responsibility of showing web content to Safari itself, avoiding the need to write custom code for built-in browsers.

Low Power modeiOS will shut down background activity and reduce performance to get you as much as three extra hours before the battery finally goes kaput.

Important News from Apple - WATCHOS 2 8

NATIVE APPSApps now run natively for betterperformance. With watchOS 2, many apps are native apps, which means they run entirely on your Apple Watch. So they load more quickly and have even greatercapabilities.

Appscan now take advantage of features like the Taptic Engine, DigitalCrown, accelerometer, heart rate sensor, speaker, and microphone.

Use more cards with ApplePay.

WATCHCONNECTIVITYWatchConnectivity saves battery life by allowing the WatchKit extension to transfer new information for the iPhone app to use when its next launched, allowing for seamless file transfers between the Apple Watch app and iPhone app. Using NSURLSession, Apple Watch can now communicate directly with known wifi hotspots using the new Tetherless Wi-Fi feature in watchOS 2.

How to make your application resizable?

SizeClasses + Autolayout

How to manage this environment?

Memory ManagementOptimize Your App Use InstrumentsFix Memory Leaks Track memory warningsFix inefficient algorithms

NSPurgableData .. NSCache Working Set Memory

To participate effectively in this environment, an iOS 9 developer must carefully tune their apps resource usage. If an app consumes too much time per frame, screen updates can fall below 60 frames per second. Under memory pressure, the system terminates the app consuming the most memory.New Features
