How would I display a text that shows an array in SwiftUI

Question

I have an array of dates

let Dates = ["2021-01-07","2021-01-19"]

and I would like to display them in a Text as a sting

Text("\(Dates)")

However I keep getting the error

Cannot call value of non-function type '[String]'.

I wanted to know if this doing this could be achieved in swiftUI.

I also wanted to know if I could display todays date in the format

YYYY-MM-DDT00:00:00Z.

I wanted to know if this doing this could be achieved in swiftUI.

Definitely!

struct ContentView: View {
    let dates = ["2021-01-07", "2021-01-19"]
    
    var body: some View {
        VStack {
            Text("Today is \(todayDate())")
            
            ForEach(dates, id: \.self) { date in
                Text("\(date)")
            }
        }
    }
    func todayDate() -> String {
        
        let dateFormatter = DateFormatter()
        dateFormatter.dateFormat = "YYYY-MM-DDT00:00:00Z"
        
        let today = Date() /// Date() is the current date
        let todayAsString = dateFormatter.string(from: today)
        return todayAsString
    }
}

Result:

Note that "YYYY-MM-DDT00:00:00Z" date format results in 2021-04-1170. You probably want something like 2021-04-27T11:56:55-0700 instead. In that case, do

dateFormatter.dateFormat = "YYYY-MM-d'T'HH:mm:ssZ"

The '' encloses custom characters that you want to add, like T. For the other format characters, check out this website.
