Swift error: 'missing return in function'?

Question

I am creating a tic tac toe game and I came upon this error that I don\'t really understand: \"Missing return in a function expected to return \'(location:String, pattern:St

Answer 1

Since your return type is an optional, you could do this:

func rowcheck(value:Int)->(location:String, pattern:String)? {
  var goodFinds = ["011","101","110"]
  var findFuncs = [checktop, checkbottom, checkmidAcross, checkleft, checkmidDown, checkright, checkLRdiag, checkRLdiag]
  for algor in findFuncs {
    var algorResults = algor(value)
    if find(goodFinds,algorResults.pattern) {
        return algorResults
    }
  }
   return nil
}
