Currently enrolled in Udemy’s- The Complete iOS 11 & Swift Developer Course Notes from Lesson 4

While Loops

• use while loops when you want the same lines of code executed when the boolean condition is satisifed
• syntax:

        while (true) {
            //do something here
        }
  

For Loops

• used to loop over collections
• traditional syntax:

        for item in collection {
            //do something here
        }
  

• enumerating syntax:

    for (index, value) in numbers.enumerated() {
        numbers[index]+= value+=1
    }
