How can I replace strings in Swift?

There are various methods for string replacement in Swift, the following list several commonly used methods:

1. The most commonly used method for replacing text in a string is using the replacingOccurrences(of:with:) method, which replaces one substring with another in a string.
   Example code:
2. let str = “Hello, World!”
   let newStr = str.replacingOccurrences(of: “World”, with: “Swift”)
   print(newStr) // Output: Hello, Swift!
3. By using the method replacingOccurrences(of:with:options:range:), you can specify the range and options for the replacement.
   Example code:
4. Replace the first 5 characters with “Hi” in the string, “Hello, World!”.
5. You can use regular expressions for replacement by using the NSRegularExpression class, which allows for more flexible matching and replacing of strings.
   Sample code:
6. Include the Foundation library. Create a new variable “str” with the value “Hello, 2022!”. Next, create a regular expression to match any digits in the string using NSRegularExpression. Replace any matches with an empty string in the original string. Print the new string without the digits.

Here are some commonly used methods for replacing strings, you can choose the appropriate one based on your specific needs.
