Your loop will be vary from 0 to 3 i.e. 0,1,2,3 but if you want it will vary from 0 to 4 then try this -

var total = 0
for i in 0...4 {
total += i
}
print(total)

i=0 => total = 0+0 =0

i=1 => total = 0+1 = 1

i=2 => total = 1+2 = 3

i=3 => total = 3+3 =6

it's simply alogrithm ;-)

i never reach 4 because you said it STRICTLY inferior to 4 =)

(Do I answer your question?)
