How to Remove Element from Array based on a Condition in Swift ?

Answer

In Swift, you can use the `filter` method to create a new array excluding elements that match the condition.

✐ Examples

1 Remove Numbers Less Than 5

In this example,

We create an array named `numbers` with elements including those to be removed based on the condition.
We use the `filter` method with a condition to create a new array excluding numbers less than 5.
Finally, we get a new array with numbers greater than or equal to 5.

Swift Program

let numbers = [1, 6, 2, 7, 3, 8, 4, 9, 5]
let filteredNumbers = numbers.filter { $0 >= 5 }
print("Array after filtering:", filteredNumbers)

Output

Array after filtering: [6, 7, 8, 9, 5]

2 Remove Strings Containing 'a'

In this example,

We create an array named `words` with elements including those to be removed based on the condition.
We use the `filter` method with a condition to create a new array excluding strings containing 'a'.
Finally, we get a new array with strings not containing 'a'.

Swift Program

let words = ["apple", "banana", "grape", "orange", "melon"]
let filteredWords = words.filter { !$0.contains("a") }
print("Array after filtering:", filteredWords)

Output

Array after filtering: ["melon"]
