Replacing a word in a range???? CHALLENGE

var peterPiper = "Peter Piper picked a peck of pickled peppers."

// Use the range() method to locate the word "picked"  in peterPiper and assign the 
//range to a variable.

var cheese = peterPiper.range(of: "picked")

for cheese in 1...8 {
          print("\cheese") is the number \(cheese + 1)")
}
//or
//var peterPiper = "Peter Piper picked a peck of pickled peppers."
// let count = peterPiper.count
 //for i in 0..<count {
 //print("Word \(i + 1) is called \(peterPiper[i])")

//how does the above look with the questions asked?
//Replace the word "picked" with "planted."  Expand the view of the result.
//Hint: You can access the upper and the lower bounds of a range with
//.lowerbound   and  .upperbound.....(((((I don't know how to replace  "picked" with "planted"


```swift
let range = peterPiper.range(of: "picked")
range?.lowerbound
range?.upperbound

if let i = peterPiper.index(of: "picked") {
    peterPIper[i] = "Planted"
}
//should look like this
//"Peter Piper picked a peck of pickled peppers."

//End Code.
//Now can anyone see if this works? Please... ?
//string interpolation? ugh
