IDEs for iOS Mobile App Development

IDE is a software building tool that has all the basic necessity of the different developer tools into a single GUI. Let us check the top two IDEs.

1. Xcode

   Xcode is the official tool by Apple. Xcode helps you to create applications for Apple tvOS, iPad, iPhone, and macOS.

   When you want to make an iOS mobile app, Xcode makes the iOS development process smooth with its various tools like an efficient code editor, compiler, debugging and build system. Primarily, it is known as an IDE (integrated development environment) used for creating and publishing iOS apps on the Apple App Store.

   While developing an iOS application Xcode also allows you to identify errors and suggest corrections with its source code checkers feature. This tool is built on top of Cocoa Touch frameworks. It is a framework provided by Apple to develop custom iOS software applications.

   Why choose the Xcode tool for iOS development?

   • Xcode is an official tool developed by Apple for creating software for different iOS devices.
   • Xcode offers testing tools like XCTest and UI Testing that allow you to solve problems faster.

   What are the top features of Apple Xcode tools?

   • Source editor that comes with advanced code completion, code folding, syntax highlighting, and message bubbles
   • Interface builder to design UI/UX without writing a single code and connect that design source code within the Xcode editor
   • Simulator to run, test, and debug the iOS apps for a streamlined development
   • Open-source LLVM compiler that helps to compile code quickly
   • A graphical debugger to debug your app within the Xcode editor with the Hover effect to dig deeper for checking content and data of the variables
