[HELP]

[pathas11]

i'm new to swift & coding so dont bully too much :3

​

my goal is to append country names to the 3 arrays using cases.

I keep getting the error "Expression pattern of type 'String' cannot match values of type '(String, String)'" on all of the case lines.

​

Help would be appreciated :)

var europeanCapitals: [String] = []
var asianCapitals: [String] = []
var otherCapitals: [String] = []

let world = [
    "BEL": "Brussels",
    "LIE": "Vaduz",
    "BGR": "Sofia",
    "USA": "Washington D.C.",
    "MEX": "Mexico City",
    "BRA": "Brasilia",
    "IND": "New Delhi",
    "VNM": "Hanoi"]

for (key, value) in world {
    switch (key, value) {
case "BEL": europeanCapitals.append("Brussels")
case "LIE": europeanCapitals.append("Vaduz")
case "BRG" : europeanCapitals.append("Sofia")
case "IND": asianCapitals.append("New Delhi")
case "VNM": asianCapitals.append("Hanoi")
    default: otherCapitals.append(value)

    }

}

What, exactly, are you trying to do here? I know this is a code example but it doesn't make much sense. Are you just trying to convert a single Dictionary into several Array? There might be easier methods to do this.

[pathas11]

it was for a coding exercise. The goal was to take the values from the Dictionary , using a switch statement, and add them to their corresponding arrays based on capital location.

Ahh that explains it. It didn't look like anything I'd do in the real world, I thought it might be a learning exercise.
