Launched a few months ago, Swift still raises doubts for many developers. The news came with the need for Apple to bring to market an easy language to learn and to use. This initiative is in line with a worldwide movement to make programming in another language that can be learned by humanity. The idea is that the Swift boost more people to set up the courage to try to be part of this world, and thus contribute to expand and solidify the application ecosystem Apple, which today is the most profitable market.
Until its release, the language most used in mobile application development for iOS and OS X environments was the Objective-C, created in the early 80s Apple was concerned to reduce the resistance to the adoption of Swift by experienced programmers. For this, allowed the new language would use the same compiler and could live with the Objective-C in the same application. That way, no one will be forced to learn it immediately, because you can continue programming the old ways and adopt new technology slowly.
But a question may be on the minds of many people: the Objective-C was not good enough? There is no doubt that this language is very powerful and has served Apple unquestionably all these years. But it is not easy to learn. The fact that it was built based on traditional C and C ++ languages created compatibility constraints that make it more difficult to understand the language, especially for new programmers.
The programming branch there is a tradition that the aim of the first application developed by a beginner is to display the message "Hello World". This is a good example to understand where Apple wants to get to the Swift language. See the table below the source code necessary to achieve the same goal in Objective-C and Swift languages:
In fact, the commands to display the message are very similar, but in Objective-C, due to backward compatibility issues may take many other lines of code.
Here we have the first great advantage of Swift language: Simplicity.
The source code is simple and concise. In addition to making life easier for programmers who can develop applications with fewer lines of code, Swift will also improve the lives of teachers, it is possible directly from the teaching of the language features. The learning Objective-C, in contrast, requires the explanation of many rules (and its exceptions) and the approach of deeper technical issues, hindering the understanding of who is not in the IT sector.
However, the simplicity becomes not less powerful language. Compatibility with the Objective-C language was maintained and the existing package features (Cocoa, Mac and Cocoa Touch for iOS) has been expanded and improved.
But Swift was not only inspired by other languages. It brought several innovations that provide multiple options for developers, as the types of Tuples and Optionals advanced data, the mutability and interpolation Strings, the Lazy properties, nested and multiple functions and return to the flexibility of the logical structure Switch. Even the definition of variables and constants has been modernized, bringing the inference of data types and greater security on the data that can be worked in an application.
The productivity and the pleasure of programming were not left out. Swift brought concepts where the prevention of errors can be done at design time, allowing applications to reach your final version more consistent and well finished. And one of the big news is the playground, amusement park not only in literal translation, which consists of a file where the programmer has complete freedom to exercise and test algorithms, and can view the results immediately, without formally create a project and meet all the build process.
Important aspects such as performance and memory management were not left out. During the presentation at WWDC, Apple showed off some cases, the processing of Collections, where an algorithm was run in Swift 1.3x faster than the same algorithm in Objective-C.
And from ARC (Automatic Reference Counting), Swift tracks and manages the use of the application memory, causing the programmer, at least in most cases, do not have to worry about this important issue, which can bring down the execution of an application.
It is expected however, some disadvantages in adopting the new language, at least for a certain period of time. Developers will have to go through a learning curve to become proficient in Swift. It will take a while for the new features to be understood and absorbed by them and can be effectively implemented in new applications. Developers will also have to get used to the syntax of the language itself, which is considerably different from already on the market.
To be used, the Swift requires the new version of Apple's development interface, Xcode 6, walking is in beta and only available to registered developers. Xcode 6 will be officially launched with the new operating system Yosemite, which has occured in October. After the official launch, the apps developed in Swift may be immediately submitted to the App Store application store.
For everyone to properly prepare for the official launch, Apple has released two free e-books and created a blog specifically dedicated to the new language:
The first e-book - The Swift Programming Language, brings all the new language content and is intended to any public, are already experienced developers or new programmers.
The second e-book - Using Swift with Cocoa and Objective-C, intended for programmers of the Objective-C language, details the compatibility and interoperability between the languages.
Both e-books are available through the iBooks app for both Mac and iOS devices.
The Official language also brings a lot of information about the new language, and is available at https://developer.apple.com/SWIFT/
You can have access to the blog created exclusively for the Swift at the address https://developer.apple.com/swift/blog/
Traditional training centers in mobile development, such as IAI (Institute for Interactive Arts), are also preparing to launch complete courses on the new language.
We can conclude that technically the Swift is very welcome. But also often make existing products and technologies, Apple reinvented programming features already used in other languages and added new features that will provide developers to create more robust applications, smaller and with optimized performance. And that could be developed in less time and therefore a lower cost, which is a competitive advantage in this market, as it will allow a good idea to be quickly implemented to maybe make it a millionaire developer.
Apple, once again, is generating a small revolution, this time in the software development market.

The advent of smartphones and tablets explosively propelled the use of mobility for users and businesses. And as a result, mobility has become one of the most challenging rupture the CIO technologies. The speed with which mobile technology evolved, the iPhone is 2007 and the iPad in 2010, most of the software and IT sectors of enterprises have yet to extract its full potential. Incidentally, exploring mobility means that all technological waves should be explored. Mobile devices allow you to create new experiences of mobility, exploring algorithms and data (big data) enables you to create more engagement with customers, who naturally already live in a context of sharing and sociability (social platforms) and all provided by a environment that is highly elastic cloud computing. In this context the mobility allows you to create engagement systems (systems of engagement) between customers, business partners and employees. Are systems, which by their nature are very different from today's enterprise systems or systems of records. The systems of engagement can be seen as an addition to the systems of records, which basically operate the transactional environment for business layer.
The crux of engagement systems are the apps. Are becoming the main point of customer contact with the companies. Their adoption has been explosive. It is estimated that by 2016 will be achieved the milestone of 300 billion downloads per year. The secret of their success is that all its complexity is hidden from the users, unlike the current client-server system where the user interacts with a significant part of the internal complexity of the systems.
Today we are experiencing a process of transformation of apps geared exclusively to end-users, which we call first generation, where isolated actions of corporate operating systems, such as calling a taxi or validate traffic conditions, to a second generation, where many of these actions will be integrated into corporate systems. Not that the apps geared to end users will disappear, on the contrary, we will see a lot of innovation, but corporate apps will popularize explosively. In this context the apps start to be viewed not only as individual productivity tools but reach the level of drivers or even be responsible for new business models of companies, creating new services or products. Yes, a smartphone is not just a device to find a taxi, but a high-tech transformational power.
However, this explosive growth demanded by the context of the apps generate an enormous challenge for companies: lack of expertise and training for the development of these new systems of engagement. Concepts like DevOps, architecture-based service APIs, user-centric design experience, based on the evolution of apps MVP (Minimum Viable Product) model are little known by most of the staff development corporations.
This new scenario implies that software architects should look at the apps otherwise, not as appendages to their corporate systems, but as a central part of its strategy to create more modern systems. Become critical components of enterprise systems. Well, first of all, in my opinion, the apps should not be seen as miniature applications or simply a variant of an existing application that runs on a mobile device. Apps are apps, a new type of programs. Thus, mobile app development requires profound changes in current processes of systems development.
A comparison with existing systems shows a very large difference. In the design of current systems, such as ERPs, place the maximum possible functionality. The more features, more complete and more "salable" becomes the system. Clear that the system becomes more complex, with upgrades in lengthy cycles (grouped updates to be provided in package upgrades), raises the cost of maintenance and operation becomes increasingly complex and costly. And often in practice we see the phenomenon of "overcapacity" when the number of features needed to exceed the customers' demands. And these, of course, question the cost of maintenance for features that add little or nothing to your business.
Apps imply simplicity. Not that they are simple in their guts, but the complexity is hidden from users. Now, because the concept embedded in apps, simplicity, can not be applied to corporate systems? In the world of apps instead of adding more features to the system, it creates a new collection of apps, which can work together, but preserving its simplicity. An example of the conceptual difference between the current model ("Old School") and the model of simplicity can be seen by comparing Word and Evernote. And this comparison can be applied to virtually any system.
Another built-in feature in the concept of apps is that they by definition are based on the design "people-centric" process rather than "process-centric". In the "process-centric" focus is the process and does not consider who the user at each moment. For example, an ERP automates a particular process and even if different users with different roles in the execution of the use case, are treated equally. The concept "people-centric" person and its function, or the context in which it is operating the service that counts. For this, of course, is necessary for the app to use your entire technological potential, as geolocation, access to contextual information (date and Social Big) and so on. The "people-centric" process considers where and how of user engagement with the app.
Perhaps the main difference is that in the current case the purpose of the system is defined by the set of features. The more features most users will use, although each of these functions use only. The "people-centric" is the opposite. There is only one purpose for the app and the user uses it within the concept of where and how you intend to use it.
Probably the future of enterprise systems architectures will be based on services offered via APIs and engagement systems gravitating around. An interesting evolution of enterprise systems, based on many of these concepts is the case Fiori SAP. Each user uses a specific app, according to your needs. In the background runs the ERP.
Apps, APIs, DevOps, MVP and "people-centric" likely to be the paradigm of development in the coming years. Anyway, we still have a long way to go, though to be traversed quickly and I think all of us who are involved with architecture and systems development should start (incidentally, as we should) be seeking to create these new business solutions. Yes, the world will be the apps ...

If you are one of the shoppers who shop through their smartphones, then definitely you must have encountered that the mobile devices has not only turned the lifestyle of consumers, but also the way people are shopping. As per the research, users are spending more and more time on shopping sites via their mobile devices, which forced the online shopping businesses to transform their e-commerce business to the m-commerce.
Online businesses have understood that they can get loyal clients just by implementing some innovative mobile strategies. Today, the mobile app developers and designers have largely contributed in developing various mobile apps for shopping which force mobile users to stick with their devices. According to a research, about 1.2 billion of users make use of their mobile devices to access several websites, in which about 15 % of online traffic is via mobile commerce, (ie. via mobile shopping). Additionally, it is also identified that 4 out of 5 users like to shop using their smartphones.
In order to be compatible with the resolution of mobile devices, developers use the responsive web design to transform a PC version of website into a mobile version. Due to the responsive web design, the website itself automatically adapt to the mobile resolutions without decreasing the quality of a website. The best advantage of mobile commerce is that, users can easily complete their purchases and payment via their mobile devices safely.
The m-commerce allows the users to select their choice of payment gateway such as debit/credit cards, paypal, internet banking or even via phone call.
It is also being said that, within the coming 4 years, half percentage of the mobile users will prefer to complete their transactions through the m-wallet. However, the use of barcode scan is necessary when users make online payment.
Another advantage is that, the users can evaluate the cost by comparing it with other prior to make purchase. Nearly 47% users have confessed that they surf information about the regional stores via their mobile phones, whereas 67% users confirms the cost on their smartphone before making purchase. Additionally, 42% of users verify the inventory before ordering and 60% of customers prefer to stay at home and buy.
Doing a product research guides the customer to make sure the credibility of the product before buying. One of the other advantages of mobile commerce is that it allows you to trace the retailer over the map using a GPS app. In order to integrate all these necessary functionalities, the Android App Development Company and iPhone Development Company are important.
Mobile devices with touch-screen technology offers a rich user experience which directly impacts the purchasing behavior of the customers. Most of the customers prefer to buy from another website, if the site content loads slowly or the transaction process is too slow.
It is just like a thumb rule, that the more time taken by website to load, the more negative will be the users experience. Hence, it is important that the e-commerce sites are tailored and customized to suit for smartphones. For every m-commerce, the success completely depends on the way the mobile applications are developed.
The biggest advantage of e-commerce website shows on Smartphone is that it creates a brand visibility. And, users tend to recommend the m-commerce site if they found it valuable and useful.
