Advantage of using stride in swift

Question

Can you explain the advantage of stride in Swift and its peculiar use?

e.g.:

for i in stride(from: 0, to: 10, by: 1) {
    print(i)  // prints from 0 to 9
}

Instead of this we can use for loop also.

Instead of stride we can also use for i in 0...10{ print (i) } — Akash, May 21 '18 at 06:31
There is no advantage if you want to increase the iterator by 1. — Sulthan, May 21 '18 at 06:32
so, if we want to increment the iterator more than 1, its not possible in for i in 0...10{print(i)}. But by using stride its possible. — Akash, May 21 '18 at 06:35

Your question appears to be asking about the benefits of stride over a basic for loop with a range such as 1..<10.

stride supports incrementing by values other than 1.

// count by 3
for x in stride(from: 3, to: 30, by: 3) {
}

// Backwards
for n in stride(from: 20, to: 0, by: -4) {
}

stride works with non-integer values.

for r in stride(from: 3.14, to: 234.14234, by: 5.6345) {
}
