How to convert First Character in String to Uppercase in Swift - Step by Step Examples

How to convert First Character in String to Uppercase in Swift ?

To convert the first character in a string to uppercase in Swift, you can use string manipulation methods such as prefix() and uppercased().

In this example,

We create a string named str1 with a value of "hello world".
We extract the first character of str1 using the prefix() method.
We convert the extracted character to uppercase using the uppercased() method.
Finally, we concatenate the modified first character with the rest of the string and print the result.

let str1 = "hello world"
let modifiedStr1 = str1.prefix(1).uppercased() + str1.dropFirst()
print("Modified string is:", modifiedStr1)

Modified string is: Hello world

In this example,

We create a string named str2 with a value of "swift".
We extract the first character of str2 using the prefix() method.
We convert the extracted character to uppercase using the uppercased() method.
Finally, we concatenate the modified first character with the rest of the string and print the result.

let str2 = "swift"
let modifiedStr2 = str2.prefix(1).uppercased() + str2.dropFirst()
print("Modified string is:", modifiedStr2)

Modified string is: Swift
