Some of the important upgrades and new features in Cocoa Touch are:

1. Drag and drop API

We can pick up items, and drag it around, and we can tap to add additional items. All of it while the system is fully responsive and active, even allowing us to drag data between applications. What’s even better is that Apple would be giving about four sessions to the developers to brief them about a few key components of this API. For using it, you only have to create a UI drag interaction which is basically a new subclass of UI interaction and attach it to the view where you need this functionality.

Similar to Gesture Recognizer, a UI interaction needs a delegate to be set on it, attached to a view, and the system takes care of everything else. Pretty easy, right? Thank Apple. The UIDragInteractionDelegate protocol gives the developers a lot of opportunities to customize the drags. After providing the data for the item to be dragged, the developers can customize lift animation and preview.

After drag is defined, we define drop. Drop has to be defined to the super view instead of individual views. The UIDropInteractionDelegate protocol gives you a whole new set of opportunities to be creative. It allows you to update UI as the drag moves, and to receive data on drop, and also to customize drop animation. Additionally, it has built-in support for TableView, CollectionView, TextView, TextField, WebView and many other existing features. It can be easily integrated with UIPasteConfiguration.

2. File Management

The latest update allows for easier access to not only locally accessible documents but also the ones on the cloud. It uses a class called the UIDocumentBrowserViewController which handles this API. It is highly customizable, and it can coordinate file access using NSFile Coordinator as well as UIDocument.

3. UI Refinements

We see a lot of UI refinements in the latest Cocoa Touch, the most visible being a larger title. But wouldn’t that give lesser space for content? Apple took care of that too. The search bar collapses, followed by the title which now shifts to a smaller navigation bar with smaller text size so that maximum space is available for content. Pull to refresh feature is automatically included in the view. UI ScrollView now comes with a lot more features to have the perfect UI and response. It automatically takes care of much of the functionalities you had to define previously. UI TableViews now have a newly unified swipe delete feature just like the one you’ve used in the mail app, as well as a lot of other features which make the UI more appealing and interactive.

4. New APIs for Swift and Foundation

We can now archive swift native types. Foundation has also added support for archiving to JSON and property lists. Another great addition is the new KeyPath type with literal syntax, and getters and setters, instead of hard coding strings. A new block based KVO makes your code shorter and more optimized, yay! We can also save the edges from system responses so that we have an uninterrupted experience while using the apps. The interaction between AutoLayout and ScrollViews has also been improved. Dynamic Type has also seen some improvements ensuring a better overall experience for the users.

5. Asset Catalogs

One of the best new features is that when the system detects a username and password, the candidate bar shows a key icon. Upon clicking the key icon, we get a list of all saved usernames and passwords which allow us to choose the username and password we want without typing it all out. Asset Catalogs now come with the feature to make named colors. Asset Catalogs would now have wide gamut color support, wide gamut colors for icons, as well as the feature of app thinning for icons. It also comes with PDF-backed images. There is support for variable screen refresh rates too.

The post WWDC 2017 Highlights: Day 2 appeared first on Mobile App Development | BrainMobi Blogs and News.

June 5 – 9 2017, will be those remarkable days.

World Wide Developers Conference (WWDC) is Apple’s annual event that brings highlight to new hardware and software that are yet to get released in the market. It is a conference held annually in California by Apple Inc. More than 5000 top mobile app developers from around the world are expected to attend this year’s 28th Apple Worldwide Developers Conference. This year WWDC has been gathering tons of rumors and speculations about What to Expect from Apple this year. So, what will they announce? The long-rumored iPhone 8, iOS 11 to macOS 10.13. What about the supposed overhaul of tvOS 11 and watchOS 11? Tune in with BrainMobi to find out.

Shashank Mehrotra and Shrestha Tripathi will be bringing back up-to-the-second news from the keynote, which is scheduled to start on June 5. We will kick start by sharing back key note speeches, event photos and more. Get all the details to make sure your week goes smoothly. So tune in early.

WHAT TO EXPECT FROM APPLE THIS YEAR?

This year, Apple is expected to start the event with the announcement of new versions of iOS, tvOS, macOS and watch OS and last but not the least the new iPhone 8. In this article we have compiled all the rumors that we have heard about, that could potentially debut at the event to give WWDC readers an idea of what to expect from Apple this year.

iPhone 8

On its 10th anniversary of iPhone, Apple is scheduled to change the rumors into reality with the launch of new iPhone 8 and it’s shaping up to be a big update. Rumors so far include that the new iPhone will have wireless charging, improved waterproofing, facial recognition, OLED and 4K display, glass body, and faster A12 processor. Apple can also bring back the revolution in smartphones by launching edge to edge display in iPhone 8. As per the sources, Apple is working on 10 different prototypes. So it’s very hard to quote what we are going to experience in the next year.

According to a report by Apple analyst KGI Ming-Chi Kuo, it’s very hard to get iPhone 8 until the end of 2018. This is because of the delay in mass production, availability of upgraded components, and various custom orders that Apple has received from its lovers. Due to the delay in production of iPhone 8, sources also say that Apple is preparing to launch iPhone 7s and 7s+.

iOS 11

iOS 11 is set to be previewed at this year’s Worldwide Developers Conference, which is scheduled to take place from June 5 to June 9 at McEnery Convention Center, San Jose, California. Apple’s operating system for iPhone’s has gone largely without design changes since 2013, but this year we are expecting some design tweaks in iOS 11 to update the look and feel of iPhone.

Well, we do not have much information, but we’ve heard some tantalizing details about the new iOS 11. This time Apple is planning to introduce Siri iCloud integration, contextual learning and group FaceTime competing Skype. The new iOS 11 will allow users to start multi-person calls (up to to 5 people) through a group conversation in iMessage. iOS 11 is also rumored to introduce a new video focused social networking app.

macOS 10.13

Each year at WWDC, Apple unveils a new version of its macOS making it available for the entire mac lovers. It has always given a sneak peek into its next Mac OS version at WWDC every year. This year Apple is expected to launch a follow-up for macOS Sierra 10.12.24 later this year at WWDC 2017. As the name is concerned, currently we do not have any rumors about what will be the name of new macOS as Apple has stopped naming its operating systems. But we are still trying to decode the name. It has been rumored that the new name can start with the letter “M”.

tvOS 11 and watchOS 4

There are rumors that Apple could possibly introduce new versions of tvOS 11 and watchOS 4 later this year at WWDC. New rumors around tvOS 11 include multi-user feature, version upgrades and account switching. The new account switching feature would allow users to access their own Apple Music libraries, iCloud Photo Libraries, and maybe even Home screen layouts. Currently, you can’t allow any of your friend to make a call or browse the internet without giving them full access to your phone. Thus, Apple is also planning to launch account switching feature for its iPhone lovers so that you can easily share your phone with your friends and family.

Apple’s watchOS 3 has bundled with a lot of new features and improvements to Apple Watch while the successor is coupled to have more advanced features. Let’s take a look at the new rumors that would tell us what’s next for watchOS 4? News bands and case finishes, built-in sleep tracking to monitor your movement, built-in FaceTime camera for video calling, upgraded heart rate app, and improved music and audio controls. Since Apple is planning to introduce watchOS 4 this year in June at WWDC 2017. This means that we can see the new look of our watchOS 4 in June 2017.

Following the conclusion, Apple is likely to provide iOS 11, macOS 10.13, tvOS and watchOS to it’s developers, giving them time to adapt their apps and take advantage of new and updated features. Developers will also be able to download the software before it’s being available to the general public. BrainMobi will continue to share up-to-the-second news of WWDC 2017 from the keynote on our social media – Facebook and Twitter accounts. The highlights of World Wide Developers Conference (WWDC) 2017, will be shared in our upcoming blog posts.
