Differences Between Swift and Objective C

Today, apps have become a crucial part of the marketing industries and mobile app development companies are now developing more apps according to customers’ requirements to gain profit. While developing the apps, the companies need to make sure that the app is pleasant, loads fast, execute even more fast, and valuable for its consumers. Programming languages live longer, but it is the market getting outdated with the use of same programming language to develop an app. If you are developing apps and not yet explored Swift, an iOS programming language then you should make a note that Swift is the language of this era which not only supercede Objective-C (the other iOS programming language) also a better option to replace embedded programming on Apple platforms.

But, how these two programming languages differ from each other? Let’s take a look at the differences between Swift and Objective-C iOS programming languages.

Swift vs Objective-C

There are many factors to consider every time before choosing any programming language before app development. It leads to confusion among the app developers which leaves a space for the discussion on which language to choose- Swift or Objective-C for building iOS application? 

Have a look at the analysis of facts given by Google trends that will solve all your doubts on choosing between the Swift or Objective-C programming languages:  

Swift vs Objective-C

Let’s take a closer look at the comparison of Swift vs Objective-C:

  • Switch is easy

In Swift programming language, a switch can be executed to all new features such as ranges, tuples, values, lists of values, wildcards, as well as lines, classes, and structures. It doesn’t ‘fall through’ by default. 

Objective-C code is less readable and more complicated. In addition to this, it is mandatory to develop a separate new structure for some Point variable.  On the other side, Swift simplifies this process.

  • User-Friendly

Swift has a more simplified syntax for creating fields and properties of the classes. Also, properties in Swift do not require instance variables. On the other end, in the latest versions of Objective-C, instance variables were created automatically and they could be set manually as well.

In Swift, instance variables cannot be created.    

  • Easy Code Compilation

This is a very interesting feature for programmers. Xcode IDE is the latest editor where programmers can run the code. This code can be compiled and executed once at this editor. This lets the programmer code and see the results directly without building a complete project and running an emulator to check everything, saving your time. In Swift, you can easily experiment with new algorithms using a great interactive environment, which is not possible in Objective-C.  

  • Better enum

Enum is referred to as lines, characters, integers, and fractional numbers in Swift programming language. Therefore, using Swift, you get a more readable and less complex code implementing the inverse transformation #toRaw which is not possible with Objective-C.   

  • Functional Programming features

In Swift, there are higher-order functions, functions as values, nested functions, closures, anonymous functions and other attributes of real functional programming. On the contrary, in Objective-C, you have to use blocks instead of functions. That’s why the code in Objective-C is 4 times lengthy and not as clear as in Swift.

Coming to the conclusion

Swift is finally declared as ABI stable and is considered as a mature language. Also, from now on the future updates in Swift will not break the current code in Swift 5. On the other hand, Apple provides good interoperability between these two languages- Swift and Objective-C. 

If you are building a binary framework, you can use Swift language to get Module Framework Stability and if you want to develop any C++ and Objective-C++ framework, at that moment you can blend the two languages- Swift and Objective-C.

Scala In Demand Technologies Built On Scala

The term Scala originated from “Scalable language” and it means that Scala grows with you. In recent times, Scala has attracted developers because it has enabled them to deliver things faster with fewer codes. Developers are now much more interested in having Scala training to excel in the big data field. The Scala community has grown over the years and it has now become a standard for enterprise, start-ups and universities alike. Scala is now being used by many companies and individuals to build their own new ideas. Play Framework, Akka, Apache Spark, etc are some of the tools and projects created using Scala. Scala is now the next wave of computation engines and more importance has been given to the speed processing rather than the size of the batch, and the ability to process event streaming in real-time. 1.Apache Spark Apache Spark can be considered as the replacement of MapReduce. In late 2013, Cloudera, the largest Hadoop vendor supported the idea of replacing MapReduce with Apache Spark. Spark is developed by AMPLab and it is a fast and general purpose engine for large-scale data processing. Spark effectively provides an alternative for Hadoop’s two stage MapReduce model. It has improved the performance of certain applications to 100 times with its fine grain operators, in-memory caching of intermediate data, and data flow optimization. 2. Scalding Scalding has been introduced and maintained by Twitter. It provides full benefits of Scala syntax and functional operations. Scala is a powerful language for solving functional problems. Scalding makes comprehensive use of Scala and it is an extension to cascading that enables application development with Scala. If we focus on the benefits of Scalding, data applications can be built with Scala. With simple and concise syntax code becomes easier to interpret. Scalding has filled the benefits of cascading application framework. 3. Apache Kafka Built and maintained by LinkedIn, Apache Kafka is a distributed streaming platform. Apache Kafka allows the user to publish and subscribe streams of data, just like a messaging system. Kafka is responsible for handling hundred of megabytes of read-write traffic per second from thousand of clients. It is also empowered by Scala and we can see the influence of the language. Real-time data pipelines and streaming apps can be built by using Apache Kafka. Yahoo Kafka Manager is also written in Scala and the web console is built using Play Framework. The Kafka Manager is being used by many teams including the Media Analytics team. It interacts with an actor-based, in-memory model built with Akka and Apache Curator. 4. Finagle Built by the people at twitter, Finagle can be considered as one of the best case using Scala. It is used to build high-concurrency servers and is an extensible RPC system for JVM. Finagle was intended to provide high performance, concurrency along with Scala and Java idiomatic APIs. Finagle is known for the optimal use of available system resources and high scalability through concurrency. It uses safe, simple and clean concurrent programming model which is based on Futures. All these results in safe and modular programs.

Web Development Using PHP And MySQL

PHP (or PHP Hypertext Preprocessor) is a server-side scripting language that is used to create dynamic web pages that can interact with databases. It is a widely-used open source language that is specifically used for web application development and can be embedded within HTML. Why PHP? The distinguishing feature of PHP is that the scripting code is executed on the server, which generates HTML that is sent back to the client. The client receives the result of executing the script without knowing the underlying code. Developers can configure the web server to process all the HTML files (containing the PHP script). PHP course is easy to learn for any newcomer, but also offers advanced programming features. Using PHP with a database system PHP, as a scripting language, is popular among web developers because of its ability to interact with database systems including Oracle and MySQL. This article discusses the use of PHP scripting language with the MySQL database. Any website can require a variety of data or information to display and to retrieve them from the database. This can include display of a simple list to the running of the website based on data stored in the database. Listed below are some examples where PHP and MySQL can be used together: • Digital Ad banners, where the PHP script can be used to retrieve a digital banner from the database, which then selects a random banner from its table records and sends it back to the calling script. The PHP script can also maintain a count of banner views and clicks from the website. • Internet forums or digital boards, which use PHP and MySQL to store and retrieve user messages. • Website designing, where the design of an entire website can be changed using a couple of PHP scripts, instead of changing and uploading each web page. The PHP script can access the MySQL database to retrieve all information about the web page. Setting up the MySQL database The procedure of setting up the MySQL database varies according to the host. Every database would require a user name and password, in order to access the database. Database administration can be done using PHP scripts or using a program like PHPMyAdmin. The next step is to create the database tables for storing the website information. Creating a database table using PHPMyAdmin is also simple. Alternatively, one can create and configure the entire database using the following PHP script: CREATE TABLE tablename { Fields } Where the Fields are coded as fieldname type(length) extra_info Example: first varchar(15) NOT NULL The following command is used in the PHP script to connect to the MySQL database: mysql_connect(localhost,$username,$password); where: • localhost is the server address on which the web site is running, • $username is the user name for the database access • $password is the password for the database access Executing PHP commands After configuring and connecting to the MySQL database, you can start executing PHP commands on the server. Following are the 2 methods of executing a PHP command: • Entering the command in PHP using the following syntax: Mysql_query($query) This form of command can be used to repeat the command simply by changing the variable. • Defining the command as a variable. The result of the operation will be assigned to the variable. Data input and output Inserting data using PHP is identical to the procedure of data input using HTML pages. The advantage of using PHP is that the script does not need to be changed for each new piece of input data. Users can also input their own data on the web page. Following is an example of an HTML page with textboxes that can be used to enter data in a form: Alternatively, you can use variables to input information into the database. Example: $first=$_POST[‘first’]; $last=$_POST[‘last’]; $phone=$_POST[‘phone’]; $mobile=$_POST[‘mobile’]; $fax=$_POST[‘fax’]; $email=$_POST[’email’]; $web=$_POST[‘web’]; … $query = “INSERT INTO contacts VALUES (”,’$first’,’$last’,’$phone’,’$mobile’,’$fax’,’$email’,’$web’)”; mysql_query($query); This script is saved in the insert.php file, which can be called from the HTML form. Using this method, data entered in the web page form is stored in the defined variables, which are then passed to the PHP. To display (or output) the entered data using PHP, you can use the following MySQL command with the result assigned to the variable. $query=”SELECT * FROM contacts”; $result=mysql_query($query); PHP provides 2 submission methods, GET and POST to get the data submitted by the form into your PHP script. GET method displays the variables and the data in the page address, while they are invisible in the POST method. For example, a script can be created that will display different web pages depending on the clicked link. yourpage.php?user=david (to show David’s page) yourpage.php?user=tom (to show Tom’s page)

IOS Application Development Guide

Developing applications have never been easy task for developers. Mobile applications industry is becoming huge and it will keep on expanding. iOS applications are actually somewhat different from android applications. Programmers starting off with iOS application development should be familiar with the basics of the Apple’s development tools. Proper iOS training will give better idea of what you can and can’t do before starting off. Here we guide you in a right way for iOS development and how to do. We provide you the languages that has to be known before developing an iOS application, details on coding environment and the Apple’s guidelines which has to be followed. Where do you start? In order to do a graphical interface for your apps, you will have to know Xcode. Xcode is the Integrated Development Environment(IDE) for Mac and iOS. Xcode is free to download from the Apple site. You are not limited to a particular language while developing apps for iOS. There are many places for you to get started, consider Apple’s own guide which helps you out in Xcode, structuring and implementing your apps and finally uploading it to the App Store. You get to know about everything under one roof here. Apple also has videos which include various parts of development. These videos are from WWDC and you will get to know tricks and tips direct from the company. You can watch the videos here. If you are looking for some places other than the official sites, then Code School offers you free iOS course which is separated into different levels and you will even earn a Course Completion Badge at the end of course. Get started for free here. You can even try raywenderlich tutorials for iOS. Following Guidelines while developing apps Following these App Store Review Guidelines will help you to develop an app which will meet the standards set by Apple. Now these guidelines are very specific as we all know the quality of apps available in the App Store. At times you might even find it tedious to follow all of these guidelines, but even if your app does not meet them even remotely, chances are that your app might be rejected during the review process. Apple has also stated some top reasons for your app to get rejected. The review of the app will be done based on some factors like app design, content, and technical details. The app might also get rejected if any controversial subject is involved. Now these might be difficult for beginners or sometimes even for professional developers, but it is better to follow these guidelines rather than getting rejected. There are even some more guidelines to follow if you are going to integrate additional functions with your app such as Apple pay. Many of the Apple API’s have their own guidelines and it is better that you are clear of this before developing your apps. iOS Application Design Guidelines Apple has a set of design and interface guidelines. To maintain its legacy, Apple wants all the apps in their store to be designed in the same way. By designing it, in the same way, means that applications should use the same basic UI elements. “The world’s most advanced mobile OS offers everything you need to design beautiful, engaging apps that radiate power and simplicity”, says Apple. Apple has provided Human Interface Guidelines page and it contains all the basics that developers will look for in both apps and icon designs. To start off with the iOS app development, Apple has also provided a set of Do’s and Don’ts that make it easier for the developers. Github and testing codes Creating a bug-free application is a myth. Applications in their early release have some bugs and it is good practices to get other people sees your code and invite beta testers to try your app. GitHub is the place for software versioning and collaborative work. GitHub provides an incredible way of linking Xcode into it. After registering on GitHub, the work done on it will be saved and accessible by other people on your team.
