WWDC 2014. Second Day Slice

The WWDC 2014 second day program consisted mainly of sessions (What's New in Xcode 6, What's New in Core Audio, Designing Accessories for iOS and OS X, Introducing HealthKit, Building Apps for Enterprise and Education, etc.), also had laboratories (Swift Lab, Installer Lab, User Interface Design Lab, File Systems Lab, etc.) and events (for example, Stump the Experts - masters of Apple troll developers).

With details of some events - Arthur Sakharov, Redmadrobot.

SESSION What's New in Xcode 6

1. Interactive Documentation
2. Playground Mode
3. Seamless Documentation

At the session, they showed how everything works with Swift and with all the new features in the new design: documentation is translated from ObjectiveC to Swift on the fly, preserving comments and header structure, some of the documentation is in the form of interactive guides with which you can play Playground Mode.

4. Xcode Localization

Completely reworked localization in Xcode. Now there are no .strings files, there is xliff, which is automatically parsed, merged and processed by Xcode when adding and changing resources.

5. @IBInspectable

Modifiers, which in one line allow rendering custom components of UIView in IB. Variables in classes can also be marked and directly edited in IB (for example, substitute pictures from resources).

6. Sleek Extension Debugging

All new extensions can be conveniently debugged. If you pull out the Notification Bar in Debug Mode, Xcode automatically attaches to the widget's process - and you can debug everything step by step.

7. Performance Tests with Regression Display

Now if you wrap everything in the measure block in XCtest, the test will automatically measure the execution time. You can make the expected plans for this time, the tests are chased several times and consider the average time. In bots, all this is collected and logged - it is convenient to watch performance online.

8. Modules and Across-project Visibility

In Swift, everything is built on modules (of type namespace in C #). Throughout the project, you can see all the code, if it is within one module. Forget about tons of imports in each file.

9. Storyboard Live Preview

All custom components are rendered and all at the same time rendered to devices in different orientations, and all this can be debugged later in the reveal-style in 3D. Generally IB is very happy. Many convenient little things.

SESSION What's New in Cocoa Touch

1. Rotations are Deprecated

All methods with rotations are deprecated. We forget about turns, now we just have autoLayout and use it. They say directly that you do not need to write anything in the code now, everything is done through a single storyboard: both iPhones and iPads are in all orientations.

2. Resizable iPad and iPhone in Simulator

The simulator now has a resizable iPhone and iPad. This is when, like in Windows / MacOSi, you can draw boundaries and change the aspect ratio right on the fly. Big iPhone is coming!

3. UIVisualEffectView - Blur, Vibrancy

There is a new class UIVisualEffectView, and he knows how to make blur. Finally, damn it.

4. Condensing Navbars

This is when when scrolling up the navigation bar becomes shallow or disappears altogether.

5. Self-sizing TableViewCells + Autolayout in Cells

Now we forget about heightForRowAtIndexPath. The cells fully work with autoLayout, and they themselves themselves, and it all works in tables.

6. Silent Notifications Without User Approval

You can not ask anything from the user to receive silent notifications.

7. Notifications With User Actions

A notification arrives, it is shown as an alertView, the user can select an action right there in it.

8. Location Based Notifications

API for notification to come when it enters or leaves a given zone.

9. Indoor Core Location

Yes, without any ibeacon navigation works inside. According to wifi, accelerometer, etc. As I understand it, so far it does not work for all buildings, but for some specially calibrated ones. And it can determine the floors (right away in the CLLocation added integer Floor property).

SESSION Designing Intuitive User Experiences

Apple UAN evangelist voiced a cool interface checklist. Big topic, which, perhaps, need to be covered separately. Stay tuned.

The next, third day of WWDC 2014 will begin in San Francisco in 2 hours.
And here is the latest report .
