Stride in Swift using for loop

Stride in Swift

Using Stride in swift is like using for loop in C – language and in C – the language you use for loop like:-

for (int i = 0; i < 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

}

And in Swift, you can use only for each loop example:-

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

for i in 0..<100 {

print(i) prints value from 0 to 99

}

When you want to increment value of like i= i+2 or i = i +3 so it’s not possible directly to increment the value of i in swift for each loop so you have to apply your own logic to increment the value of i, like in C language. By stride method you can increment value stride contains two methods : –

stride(from:to:by:)
stride(from:through:by:)

Using stride(from:to:by:) it will not include the value of last value that you will give to: field and set by: field value that is incremented value example:-

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

for i in stride(from: 0, to: 100, by: 1) {

print(i) // prints from 0 to 99 and by is increement value i.e. 1

}

Using stride(from:through:by:) it will include the value of last value that you will give through: field and set by: field value that is incremented value example:-

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

for i in stride(from: 0, through: 100, by: 1) {

print(i) // prints from 0 to 99 and by is increement value i.e. 1

}
