Hi When Paul demonstrating closure , he used sorted (by: code of closures).

https://www.hackingwithswift.com/quick-start/beginners/how-to-use-trailing-closures-and-shorthand-syntax

let team = ["Gloria", "Suzanne", "Piper", "Tiffany", "Tasha"]

let captainFirstTeam = team.sorted(by: { (name1: String, name2: String) -> Bool in
    if name1 == "Suzanne" {
        return true
    } else if name2 == "Suzanne" {
        return false
    }

    return name1 < name2
})

print(captainFirstTeam)

Quetions: Does this mean sorted() is taking in the returned Bool generated by the closure as a parameter ?

How do I know what type of parameters sorted are meant to take in ? Or I could just pass in any type of parameters to sorted ?

Thank you in advance,

Boat

Thank you @roosterboy !

It helped me a lot to understand the "name1" and "name2" parameters when I put 'print' commands to see the action happening:

func captainFirstSorted(name1: String, name2: String) -> Bool {
    let captain = "Suzanne"
    if name1 == captain {
        print("\(name1) is being compared to \(name2), and \(name1) should come first")
        return true
    } else if name2 == captain {
        print("\(name1) should not be before \(name2)")
        return false
    }
    print("\(captain) is not being compared, so just sort \(name1) and \(name2)")
    return name1 < name2
}
