Why use Swift
It takes less time to build iOS apps using Swift, due the use of Automatic Reference Counting methodology which helps in work tracking and managing the app’s memory usage.
New features can be added when needed and the amount of code that is required for repetitive statements and string manipulation is reduced due to modern language features.
Safe and swift
Swift allows you to see the errors in the code instantly and fix them immediately, greatly reducing the time and effort needed for bug fixing and eliminating the risks of deploying low quality code.
Increases automatic and high-performance memory management thus increasing productivity and helps in responsive graphics and user inputs on iPhone, Apple Watch, or iPad.
