# Solved: for loop high to low

Fashion, much like code, has its own language and trends, constantly monophonic and dynamic in its representation. Just as loops are a fundamental part of programming in Swift, trends and styles form the core of fashion.

One of the most central constructs in any programming language including Swift is the ‘for’ loop. It is a control flow statement that allows code to be executed repeatedly. These loops can be navigated in various ways, one of which is from high to low.

```for index in stride(from: 10, through: 1, by: -1) {
print(index)
}
```

## Decoding the Code

Just as a runway show opens with its prime looks, let’s start by decoding the first piece of our loop. In Swift, the ‘for-in’ loop is used when you want to run a set of instructions for a specific number of times.

The word ‘index’ is a variable that temporarily holds the value of the current element in the loop. It’s like a model on a runway, bringing with her a new trend or piece each time she walks down.

The ‘stride’ function can be compared to our runway. It determines the direction and steps of our fashion show (or in this case, our loop). ‘From: 10’ means the loop will start from the number 10, just like our fashion show might start with autumn trends.

## Stride

Stride function in Swift is the crucial ‘trend-setter’ in our code. It sets the direction from ‘high to low’, i.e., decrementing the loop from 10 to 1. The parameters ‘through: 1’ and ‘by: -1’ indicate that the loop will continue down to 1, decreasing by 1 with each pass.

In the context of fashion, imagine you’re watching a fashion show that starts with heavy winter clothing and ends with light summer dresses as the trends pass from high to low.

## Print Function

The print function is like the shutter of a camera, capturing each outfit (or number) as it goes by. Each number is printed within each loop cycle.

Like a swift change of dresses in a runway, this code smoothly moves from the high value of 10 down to the lowest value of 1.

Just like in fashion where we wear different outfits for different occasions or seasons, in Swift programming, we use different types of for loops for different purposes. Striding from a higher number to a lower one might not be the ‘trendiest’ or most common use of Swift syntax, but a good developer learns to appreciate every style of coding, just as a fashion connoisseur learns to appreciate every style of outfit.

Summarizing, the high to low for loop in Swift is not only essential, but also presents a unique style of iterating through a collection. Use it elegantly and thoughtfully, just as you would with a fashion ensemble. And remember, coding and fashion both require an eye for detail, a dash of creativity, and plenty of practice.
