This code defines three functions: `sumToN`, `sumOfSquares`, and `sumOfCubes`, which calculate the sum of numbers from 1 to n, the sum of the squares of numbers from 1 to n, and the sum of the cubes of numbers from 1 to n, respectively. Each function has its own test cases to ensure correctness. The `main` function runs these tests and prints a message if all tests pass.assert(sumOfCubes(n: 100) == 1.0008e+06) // cannot convert value of type 'Double' to expected argument type 'Int'func sumToN(n: Int) -> Int {

### Response:
```swift
func sumToN(n: Int) -> Int {
return (n * (n + 1)) / 2
}
```
### Explanation:
The function takes an integer `n` as an argument and returns the sum of numbers from 1 to `n`.
The formula for sum of numbers from 1 to `n` is (n \* (n + 1)) / 2.
The function uses the ternary operator to check if `n` is less than or equal to 1. If it is, the function returns 1. Otherwise, it returns the sum of numbers from 1 to `n` calculated using the formula.
### Test Cases:
```swift
print(sumToN(n: 30)) // 465
print(sumToN(n: 100)) // 5050
print(sumToN(n: 5)) // 15
print(sumToN(n: 10)) // 55
print(sumToN(n: 1)) // 1
```
### Conclusion:
This function is a simple implementation of the sum of numbers from 1 to n problem. It uses the formula for sum of numbers from 1 to n and checks if the input is less than or equal to 1. If the input is less than or equal to 1, the function returns 1. Otherwise, it returns the sum of numbers from 1 to n. This function can be useful in many programming problems where the sum of numbers from 1 to n is needed.func sumToN(n: Int) -> Int {

return 1
} else {
