Stride method
In Swift, the stride() method is used to create a sequence of values that are separated by a specific amount, or "stride". The method is useful for iterating over a range of values with a specified step size.
Here's the syntax of the stride() method:
stride(from: startingValue, to: endingValue, by: strideValue)
The from parameter specifies the starting value of the sequence, the to parameter specifies the ending value (non-inclusive), and the by parameter specifies the stride value.
Here's an example of using stride() to print out the even numbers between 0 and 10:
for i in stride(from: 0, to: 10, by: 2) {
print(i)
}
This will output:
0
2
4
6
8
Note that the ending value is not included in the sequence, so the number 10 is not printed in this example. If you want to include the ending value, you can use the through parameter instead of to:
for i in stride(from: 0, through: 10, by: 2) {
print(i)
}
This will output:
0
2
4
6
8
10
