Index for substring operations in Swift?

In Swift, working with substrings is an essential skill for any developer. Swift provides various methods to efficiently manage and manipulate substring operations.

Using Swift Index for Substring Operations

To access a substring, you can use the index of the original string. Here's a simple example that demonstrates this:

let myString = "Hello, Swift!" let startIndex = myString.index(myString.startIndex, offsetBy: 7) let endIndex = myString.index(myString.endIndex, offsetBy: -1) let substring = myString[startIndex...endIndex] print(substring) // Output: Swift

This example shows how to create a substring that extracts the word "Swift" from the original string.
