Editor not working right?

Hey, ive written 2 versions of this code, both come up with the error "You must use an if statement" however they compile fine in xcode, both iterations are below, can you see an issue?

let months = [1, 2, 3]

for month in months { if(month == 1) { println("January"); } if(month == 2) { println("February"); } if(month == 3) { println("March"); } }

for i in months { if(i == 1) { println("January"); } if(i == 2) { println("February"); } if(i == 3) { println("March"); } }

months.swift 
let months = [1, 2, 3]

for i in months {
 if(i == 1) {
  println("January");
 }
 if(i == 2) {
  println("February");
 }
 if(i == 3) {
  println("March");
 }
}

Hi Paul,

Whislt I don't think it would cause a problem, your code doesn't need the semi-colons at the end of each line. However, this code works:

let months = [1, 2, 3]

for month in months {
  if month == 1 {
    println("January")
  }
  if month == 2 {
    println("February")
  }
  if month == 3 {
    println("March")
  }

}

The compiler was playing up intermittently yesterday - it wanted incorrect code entering first (add a couple of incorrect brackets to your code) before it would pass the subsequently corrected code. I don't know if that persists today.

Steve.

It seems to be the brackets around your conditional tests that are failing the compiler tests. Not sure I agree with that - it shouldn't make a difference.

EDIT No it isn't - it is the lack of space between the if keyword and the bracket. Again, not sure I agree with that!!

Thats some old habits from my PHP syntax, will need to try and forget about using them. Thanks Steve.

I always use too many code ornaments like that - it just reads more easily to my little brain!
