Can't understand this task, how to write this code:

"Let's get some practice in creating a protocol with an associated type so we're familiar with the syntax.

Declare a protocol named ConfigurableRow with an associated type object.

Add a single requirement to the protocol - a function named configure with a single argument of type Object. Give the function an external name of with and local name of object."

Hello,

To name an associated type, this is what you need to do.

protocol ConfigurableRow {
  associatedtype Object

  func configure(with object: Object)
}

Hope this helps you.
