Answer

To append a character to the end of a string in Swift, you can use the += operator or the append() method.

✐ Examples

1 Append '!' to "Hello World"

In this example,

We create a variable named str1 with a string value of "Hello World".
We then use the += operator to append the character '!' to str1.
Finally, we print the modified string to the console.

var str1 = "Hello World"
str1 += "!"
print(str1)
