The “stride()” function is a built-in function in Swift that allows the programmer to create a range or sequence of values, stepping over some increment. It provides a way to move from a starting value to an end value using any increment and even lets you specify whether the upper limit is inclusive or exclusive.

The function comes in various forms and it can be used with a wide range of data types that support the “Strideable” protocol, such as integers, floating-point numbers and even dates.

The most common use of “stride()” is to generate a specific sequence of numbers with a certain step or increment. Here is an example code that uses “stride()” to generate an array of numbers:

let numbers = stride(from: 0, to: 100, by: 7)
print(Array(numbers)) 

// Output: [0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98]

This code uses “stride()” to create “numbers” that starts at 0, stepping up to, but not including, 100 with an increment of 7. The output shows the array of numbers divisible by 7 without remainder generated. You can also use a for loop to generate a similar output.

Quick notes

• In summary, “stride()” function provides a versatile way to generate sequences of values with specific increments, skips, and ranges.
