dropFirst() Syntax

The syntax of the string dropFirst() method is:

string.dropFirst(i: Int)

Here, string is an object of the String class.

dropFirst() Parameter

The dropFirst() method can take a single parameter:

• i (optional) - number of characters to be dropped from the beginning of the string

dropFirst() Return Value

• returns a substring after removing the specified number of characters from the beginning of the string.

Example 1: Swift String dropFirst()

var str = "Hello World"

// remove first character "H" from str
print(str.dropFirst())  // ello World

var str1 = " Hello World"

// remove whitespace at the beginning of str1
print(str1.dropFirst())  // Hello World

Output

ello World
Hello World

In the above example, since str1 starts with whitespace, str1.dropFirst() removes the whitespace from the beginning of str1.

Example 2: Drop Multiple Number of Characters

var str = "Hello World"
print(str.dropFirst(6))

var str1 = "Learn Swift"
print(str1.dropFirst(7))

Output

World
wift

Here,

• str.dropFirst(6) - removes the first 6 characters from str
• str1.dropFirst(7) - removes the first 7 characters from str1
