iOS, as we all know, is an operating system, designed and developed by Apple Incorporation and runs exclusively on Apple hardware for iPhones, iPads, and iPods. The original idea behind designing the OS was to develop such an interface that could run applications easily on the smaller screen of the phones. This is how iPhones came into play. Like any other mobile operating system, iPhone offers a variety of apps that can be used by the user. In earlier versions, the app development was carried out using programming languages such as C and C++. However, nowadays the advanced versions use the languages like Objective-C and Swift. Talking about the latest and trending language, Swift is ruling the iOS. Some various iOS app development tools offered are:

• Hotfix Native iOS Apps

With this tool, code levels are pushed instantly to native Objective-C apps instantly. This tool allows direct access of app’s methods and patches them by providing app alert messages.

• Qordoba

A local SDK that works with local files and assets; its main aim is parsing, in other words establishing connectivity between the app and the database related to it.

• Charter

A great iOS app development tool that is basically rendered by the Swift language that keeps up with this programming language mailing list on iPhones or iPads. It offers both online as well as offline view and supports message threading for the conversation.

• Swift Express

A simple and powerful web application tool written in Swift that contains a framework and simple routing mechanism. It manages the dependencies of the project and helps in running the app.

• Gitter

It is built on the top of GitHub and is used for public and private chats. It allows the tight collaboration within organizations. It's aimed specifically at developers.

• Crayons

It is a plugin that improves working with colors in the project. It gives access to the custom colors that have been defined in the code. A color pallet can be shared in the file which can be accessed by writing suitable methods accordingly.

• iOS Up

It includes free software that can be downloaded easily. It provides quality assets as well as a market to buy those assets.

• Jazzy

It is a code used for the documentation of any app. As we all know, documentation is the key attribute in the development of any app from the programmer’s point of view. A documented file enables the programmer to understand the main aim of writing the code.

These are some of the famous and most widely used app development tools. Although there are many more tools out there, these are widely used in the integrated app development environment (IDE) for developing Swift or Objective-C based web applications. iOS app development is mostly done by using these kinds of frameworks, as they provide an integrated environment for an easy and smooth development of mobile applications. While it may lack in some features by other mobile operating systems, iOS app development has its own set of advantages, which are limitless.
