How to Concatenate Strings in Array in Swift

How to Concatenate Strings in Array in Swift ?

Answer

To concatenate strings in an array in Swift, you can use the `joined(separator:)` method or a loop to iterate through the array and concatenate each element.


✐ Examples

1 Concatenate Strings in Array with joined(separator:)

In this example,

  1. We create an array `words` with strings.
  2. We use the `joined(separator:)` method with the array to concatenate strings.
  3. We print the concatenated string.

Swift Program

let words = ["Hello", "World", "!"]
let concatenated = words.joined(separator: " ")
print("Concatenated String: \(concatenated)")

Output

Concatenated String: Hello World !

2 Concatenate Strings in Array with Loop

In this example,

  1. We create an array `words` with strings.
  2. We initialize an empty string `concatenated`.
  3. We use a for loop to iterate through the array and concatenate each element to `concatenated`.
  4. We print the concatenated string.

Swift Program

let words = ["Hello", "World", "!"]
var concatenated = ""
for word in words {
    concatenated += word
}
print("Concatenated String: \(concatenated)")

Output

Concatenated String: HelloWorld!
