Below is the option I tried

Answer 1

You are looking for the “closed range operator”. It is spelled ...:

for i in 1 ... 3 {
    print(i)
}

You can read more about it under “Basic Operators” in The Swift Programming Lanugage.

Answer 2

in c / java:

for(int i=1 ; i<=3 ; i++)
    print(i)

in swift:

for i in 1 ... 3 {
    print(i)
}

in c / java:

for(int i=1 ; i<3 ; i++)
    print(i)

in swift:

for i in 1 ..< 3 {
    print(i)
}
