Changes/improvements in Strings

Undoubtedly, the String is one of the majorly used data types in all the programming languages. Apparently, it is the data type that mankind understands better. Strings are important to the extent that they have the ability to significantly change our perception of how difficult or simple it is to learn a programming language. Hence, it becomes really important to follow any development to this data type. Strings received a major overhaul with Swift 4, making them collections of characters. In the earlier versions, several times, Swift, with its complicated way of handling subStrings and characters, went overboard in advocating accuracy over convenience.
