In this video, we’ll be exploring one of the often-overlooked features of Swift – the StaticString. You might have seen it in some method signatures, but not really sure what it is or what it’s used for.
StaticString is a type in Swift that represents a string that is known at compile-time. Unlike a regular string, a StaticString is not dynamically allocated and can be used in performance-critical parts of your code. It’s also an important tool for working with low-level C APIs.
In this video, we’ll cover the basics of StaticString, including its syntax, creation, and use cases. We’ll also demonstrate some common scenarios where you might want to use a StaticString over a regular string, and how it can help you write more efficient and safer code.
By the end of this video, you’ll have a good understanding of what a StaticString is, and when you should consider using it in your own Swift projects. Whether you’re a beginner or an experienced developer, you’ll find something useful in this video.
So, if you’re curious about this lesser-known feature of Swift, join us and let’s dive into the world of StaticString!

If you don't include the # symbols, the string literal will be treated as a regular string, which is not optimized for performance and does not have the same guarantees as a staticString
let greeting: staticString = #"Hello, playground!"#
Also
var greeting: staticString = #"Hello, playground!"#
is valid but not recommended.
I truly love your channel and especially this series of short videos where you explain kind of hidden features, but after this episode I feel like a fool because I do not get at all why they have included this type 😅
nice
When you make that custom initializer you’re taking off a type-safety guardrail. 😅
Waiting for rick and morty series 😰
Hi Afraz, can you please fix the typo / spelling of this Title “ StaticString”
