In Swift, the for loop is used for iterating over a sequence, such as an array, a range of numbers or a string.
Here is an example of using for loop with an array of integers:
let numbers = [1, 2, 3, 4, 5]
for number in numbers {
print(number)
}
In the above code, numbers is an array of integers and we use for-in loop to iterate over each element in the array. The variable number is used to represent the current element being iterated over. In this case, the loop will iterate 5 times (the length of the array) and print each element to the console.
Another example of using for loop is with a range of numbers:
for i in 1...5 {
print(i)
}
In this case, 1...5 is a range of numbers from 1 to 5. The loop will iterate five times and print each number to the console.
Lastly, here is an example of using for loop with a string:
let name = "Swift"
for character in name {
print(character)
}
In this case, name is a string and we use for-in loop to iterate over each character in the string. The variable character is used to represent the current character being iterated over. The loop will iterate 5 times (the length of the string) and print each character to the console.
