Try this.
protocol Position {
var x: Double { get set }
}
struct Car: Position {
var x: Double
}
func move(item: inout T) where T:Position {
item.x += 1
}
var car = Car(x: 50)
move(item: &car)
car.x // 51

In your example, the compiler needs a parameter of type Position. Car is a type
of Position, but they are not interchangeable. See below:

- Why Swift continues to not support Float80 math functions?
Example:
print("\( log( Float( 1.0 ) ) )")
print("\( log( Double( 1.0 ) ) )")
// print("\( log( Float80( 1.0 ) ) )") // don’t compile and logl is unavailable
- Why min and max continue to not act like fmin and fmax (IEEE 754 standard)?
