If Statements (Immutable error)

Not sure where I'm going wrong. The " n % 3 = 0 " kind of seems off to me because one is a variable and one is a number value, but not sure how else I can do it.

Thanks in advance

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

for n in 1...100 {
    // Enter your code below
    if n % 3 = 0 && n % 7 = 0 {
    results.append(n)

   }


    // End code 
}

First, you need the equals sign == or not equals sign !=, instead of the assignment operator =. Second, to see if a number n is odd you check to see if n % 2 is not equal to 0, i.e., if there is a remainder after dividing by 2:

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