Apps creation for mobile phones is rapidly gaining widespread popularity. Almost everyone today owns a mobile phone, cell phone or smartphone. Downloading new apps for your smartphone has become a popular activity. Have you ever wondered how these apps are developed? Continue reading to learn more about the behind the scenes steps apps creation developers take to bring new apps for you to download to your smartphone.
The two most popular platforms for apps creation and development are the iOS and Android. Apps developed for Apple iPhones run on the iOS platform. The languages used for iOS development are the older Objective-C and the newer Swift. Android app developers use Java. Apple’s iOS Dev Center and Android Developers Training are the two best places to learn how to code for either iOS or Android mobile phone devices.
Apple first introduced the Swift programming language at their Worldwide Developer Conference (WWDC) in 2014. This newer coding language replaces Objective-C that first appeared in the 1980s. Swift makes error-free coding easier and more concise. Apple introduced Swift 2.0 at the WWDC 2015 conference.
Learning the Swift programming language is much easier than learning Objective-C. This makes it more appealing to iPhone app developers. Apple wins by obtaining more support for Apple’s platforms and products. Apple also has the flexibility to change, update and add functions to the Swift programming language. Swift makes it more difficult to move apps across various mobile platforms. This means that Apple’s ecosystem offers content that is more exclusive and less portability.
Apple uses Swift to build their operating systems for their products. Developers use Swift to develop mobile applications and programs for Apple’s iOS, tvOS, watchOS, OS X and tvOS platforms.
Java is the official language that Android mobile app developers use. Sun Microsystems first introduced Java in 1995. Both smartphone and mainframe computers run apps and programs developed using Java.
Java relies on a “virtual machine” that translates Java bytecode. Each platform that runs Java requires a virtual machine (VM) implementation. Dalvik is the VM Android devices use. The virtual machines interpret the bytecode. Bytecode is a set of instructions that the CPU processor uses to execute the Java programs. VMs use technologies such as just-in-time compilation (JIT) and ahead-of-time compilation (AOT) to speed up program processes.
Windows, Linus or OS X are the development platforms for Android apps. The Java compiler will convert the source code into bytecode. The VM built-in to Android executes the bytecode. iOS uses a native compiler to turn Objective-C into ARM machine code. Here is one place to learn mobile app development.
