Error "No exact matches in call to initializer" - swift

Question

I am a beginner developer and I want to add my price variable which is a double next to the title variable in my view. When i try Text(price) is is giving me the error "No exact matches in call to initializer". Is this because I cannot use a double inside a Text?
import SwiftUI
struct TaskRow: View {
var task: String
var price: Double
var completed: Bool
var body: some View {
HStack(spacing: 20) {
Image(systemName: completed ?
"checkmark.circle" : "circle")
Text(price) "No exact matches in call to initializer"
Text(task)
}
}
}
struct TaskRow_Previews: PreviewProvider {
static var previews: some View {
TaskRow(task: "Do laundry", price: 1.00, completed: true)
}
}

The issue is Text takes in a String, so you just need to convert the Double to a String first. You can do this if you want to plan for locale or different currencies
import SwiftUI
struct TaskRow: View {
var task: String
var price: Double
var completed: Bool
var priceString: String {
return price.toLocalCurrency()
}
var body: some View {
HStack(spacing: 20) {
Image(systemName: completed ?
"checkmark.circle" : "circle")
Text(priceString)
Text(task)
}
}
}
struct TaskRow_Previews: PreviewProvider {
static var previews: some View {
TaskRow(task: "Do laundry", price: 1.00, completed: true)
}
}
// This could be in another file
// Extension to convert doubles to currency strings consistently
extension Double {
func toLocalCurrency() -> String {
let formatter = NumberFormatter()
var priceString = self.description
formatter.locale = Locale.current
formatter.numberStyle = .currency
if let formattedTipAmount = formatter.string(from: NSNumber(value: self)) {
priceString = formattedTipAmount
}
return priceString
}
}
You could also use any of these if you don't want to bother with Locale for now:
Text("\(price)") // 1.00
Text(price.description) // 1.00
Text("$\(price)") // $1.00
