Swift 5 To Upper - Swift

Introduction

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Swift 5 is the latest version of the language and provides several new features and improvements to enhance developer productivity.

In this article, we will focus on how to convert a string to uppercase in Swift 5.

Code Snippets

To convert a string to uppercase in Swift 5, we can use the uppercased() method. Here is an example:

let str = "hello, world!"
let upperCaseStr = str.uppercased()
print(upperCaseStr) // output: HELLO, WORLD!

The uppercased() method returns a new string that is the uppercase equivalent of the original string.

Explanation

In the example above, we first create a string str that contains the text "hello, world!". Then, we use the uppercased() method to convert str to uppercase and assign the result to a new string upperCaseStr.

Finally, we print the value of upperCaseStr, which is "HELLO, WORLD!".

Conclusion

Converting a string to uppercase in Swift 5 is a simple task that can be achieved using the uppercased() method. With the latest version of Swift, developers can enjoy an improved syntax and new features that make it even easier to write clean and efficient code.

Happy coding!
