iOS Swift 2.0 Collections and Control Flow Control Flow With Conditional Statements Working with Logical Operators

I am trying to find out what operator I need to use for this to satisfy the conditions.

I am sort of stuck on this part. I am not sure what I should put after I have the if statement in.

logicalOperators.swift 
var results: [Int] = []

for n in 1...100 {
    if results % 3 = 0 && results % 7 = 0 {

      }


    // End code 
}

It's not so much the operator, but the conditions:

for n in 1...100 {
    // Enter your code below
    if n % 2 != 0 && n % 7 == 0 {
      results.append(n)
    }
    // End code 
}

To see if n is odd use this condition: n % 2 != 0. What that says is the remainder of n divided by 2 is not 0, i.e., n is odd. To see if n is evenly divisible by 7 use this condition: n % 7 == 0.

Note that equals in swift (and many other languages) is ==, as = is the assignment operator.
