• It is one of the most useful programming languages which has easy to add new features which makes swift high- level language
• It is one of the best coding language to learn that does not have long code line.
• Automatic Memory Management feature prevents the memory leaks.

Cons:

• With the continues updating of swift versions of Apple, Swift is somewhat unstable
• As it is a new programming language the pool of Swift developers is very limited

Usage applications:

Swift is specially designed language which works with Apple's Cocoa and Cocoa Touch frameworks to create all types of iOS apps.

Salary: An average salary for iOS developer in the United States is around $130,801 per year

Learning difficulty: Easy
