Stride in Swift using for loop

We’ll explore how to utilize the Stride in Swift using for loop to iterate over ranges with custom step values.

The ‘for’ loop is a powerful tool for iterating over a range of numbers with a specific increment.

The ‘stride’ function provides an efficient way to accomplish this.

The Traditional Approach

Using ‘stride’ is like using for loop in C language.

for (int i = 0; i &lt; 100; i++){
    print(i) // it will prints value from 0 to 100
}

for (int i = 0; i < 100; i++){

print(i) // it will prints value from 0 to 100

}

In Swift, you can use for in loop as below example:-

for i in 0..&lt;100 {<br>   print(i) //prints value from 0 to 99<br>}

1	for i in 0..<100 {<br> print(i) //prints value from 0 to 99<br>}

Introducing Stride in Swift using for loop

The ‘stride’ function provides a more elegant solution for iterating over ranges with custom step values.

There are two ways to use stride.

stride(from:to:by:)

Using stride(from:to:by:) will not include the value of last value that you will provide on the “to” parameter.

“by” parameter takes the amount to step by with each iteration.

for i in stride(from: 0, to: 100, by: 1) {<br>    print(i) // prints from 0 to 99 and by is increment value i.e. 1<br>}

1	for i in stride(from: 0, to: 100, by: 1) {<br> print(i) // prints from 0 to 99 and by is increment value i.e. 1<br>}

stride(from:through:by:)

Using stride(from:through:by:) will include the value of last value that you will provide on the “through” parameter.

“by” parameter takes the amount to step by with each iteration.

for i in stride(from: 0, through: 100, by: 1) {<br>    print(i) // prints from 0 to 100 and by is increment value i.e. 1<br>}

1	for i in stride(from: 0, through: 100, by: 1) {<br> print(i) // prints from 0 to 100 and by is increment value i.e. 1<br>}

Conclusion

Using the ‘stride’ function within a ‘for’ loop in Swift allows for efficient iteration over ranges with custom step values. Whether you’re working with inclusive or exclusive ranges, ‘stride’ provides a clean and concise syntax for achieving the desired result.
