newValue is an implicitly defined variable in Swift. It's used when you didn't provide any named argument to the setter method.
Here.
set(f) {
celsius = (f-32)/1.8
}
This is one way to write the setter method, I passed in the f argument.
set {
celsius = (newValue-32)/1.8
}
Here's another way, I didn't pass in argument, so newValue was implicitly call-in as argument to the setter method.
The 2 ways of defining setter method here are fundamentally equivalent.

celsius = (newValue-32)/1.8

Courses Plus Student 1,758 PointsHow can xcode understand, what i mean with newValue? Because of I wrote it under "var fahrenheit" ?
