String type is an important component of any programming language. The most useful information that user reads from the window of an iOS application is pure text.

To reach a higher number of users, the iOS application must be internationalised and support a lot of modern languages. The Unicode standard solves this problem, but creates additional complexity when working with strings.

On one hand, the language should provide a good balance between the Unicode complexity and the performance when processing strings. On the other hand, it should provide developer with comfortable structures to handle strings.
