Do you want to develop an iOS app for your personal use or a business and you don't know how to code or develop at all? Where do you start and what do you need in order to create an iPhone or iPad app? First you need the right tools for the job and here you can find the necessary languages you need to know for iOS app development.

Design a perfect iOS app

Xcode: Xcode is a free IDE (integrated development environment) software development tool developed by Apple for creating applications for iOS. It is mainly a development environment in which you write your programs and the latest version is Xcode 6. Xcode has many features including a source editor for writing code, and facilities to design and test the app's user interface. There is lots of Xcode information at the Apple website and download links. Here are some of the main features of Xcode 6:

  • Extensions and Frameworks
  • Game Building
  • Localization
  • Xcode Server
  • Storyboards for OS X 

iOS SDK: This allows developers to create apps for the iPhone and iPad and test them in an iPhone simulator, which is much easier than using a real iPhone. The SDK includes the Instruments, Xcode IDE, frameworks, iPhone simulator and samples, Shark analysis tool, compilers and more. To download the iPhone SDK it is necessary to have an Apple ID (iTunes store account). There is an iPad download too. Latest stable version of SDK is iOS 8.2 and in Beta version iOS 8.3 beta 4 released on 24 march 2015. Here are some features of latest SDK: 

  • WatchKit support
  • Apple Watch Bluetooth support
  • Glucose tracking

Objective-C: Objective-C is an object-oriented programming language and it is the primary language which is used when you develop applications for the OS X and iOS operating systems. Objective-C was created by Brad Cox and Tom Love in 1980 at their company Stepstone. Here are some of the main features:

  • Classes are objects
  • Dynamic typing
  • Optional static typing
  • Categories
  • Message sending
  • Expressive message syntax
  • Dynamic run-time
  • Automatic garbage collection 

Swift: Swift is a programming language developed by Apple for iOS and OS X development at Apple's 2014 Worldwide Developers Conference. It is designed to code with Cocoa and Cocoa Touch frameworks and it is a safer coding language than Objective-C. It is built with the LLVM compiler framework included in Xcode 6. Swift is ready for your next iOS application or updating in your current app because It works side-by-side with Objective-C. Swift 1.1 was launched on October 22, 2014, with the launch of Xcode 6.1. There are most important features of swift language as follows: 

  • Dictionaries
  • Optional semicolons
  • Automatic reference
  • Inferred data types
  • String templating
  • Protocols 
  • Data structure declarations  

Mac OS X: An Apple Mac is an essential part of the iOS app development kit and all the app development tools are designed for it. You won't get very far with iOS app development if you only have a Windows PC.

Cocoa Touch: Cocoa Touch is a user interface framework for building apps. It allows the use of hardware and features that are not found in Mac OS X. Cocoa Touch follows Model-View-Controller (MVC) architecture. There are some feature of Cocoa Touch as follow: 

  • Document Picker
  • TextKit
  • UIKit Dynamics
  • Multitasking
  • Auto Layout
  • Storyboards
  • UI State Preservation
  • Apple Push Notification Service Etc.
