SwiftUi create function with array as parameter and also array type of element-CodePudding

I'm looking to do a function which take all the information of one Element of my structured array. And as I would like to do it on many array (of same Type) and many elements of this array I'd like to do a single function which take in parameter the array's name and the Array's element where I would like to work.

My array exemple :

class FlightLibrary: ObservableObject{

    @Published var testFlight = [
        Flight(seTime: "00:20", meTime: "", nightTime: "", ifrTime: "", captainTime: "00:20", copilotTime: "", dualTime: ""),
        Flight(seTime: "00:40", meTime: "00:20", nightTime: "", ifrTime: "", captainTime: "00:20", copilotTime: "", dualTime: ""),
        Flight(seTime: "00:35", meTime: "", nightTime: "00:20", ifrTime: "", captainTime: "00:20", copilotTime: "", dualTime: "")
        
    ]
}

And my attempt for my function :

func GetSpecificTotalTime(inArray: Array<Flight>, ofTime: Array<Flight>.Element) -> String{

    var specificTotalTime: String = ""
    var specificTimeInt: Int = 0
    
    for i in inArray{
        let stringValueToAdd: String = i.oftime
    }
    
    return specificTotalTime
}

Here I've my function where, for exemple, I'd like to work in my array testFlight on the element .seTime. So I would have something like :

GetSpecificTotalTime(inArray: testFlight, ofTime: seTime)

But in my function the line let stringValueToAdd: String = i.oftime didn't work. Here I want to fil stringValueToAdd by the value which is on enteredArray[i].enteredElement and after work with this value before going to the next index.

How could I do that ?

CodePudding user response：

The second parameter is not an array. Array<Flight>.Element is just a Flight.

A possible way is to specify a key path as second parameter for example

func getSpecificTotalTime(inArray: Array<Flight>, ofTime: KeyPath<Flight,String>) -> String {

Then you can get any string property with

for i in inArray{
    let stringValueToAdd: String = i[keyPath: ofTime]
}

and call it

getSpecificTotalTime(inArray: testFlight, ofTime: \.seTime)
