SwiftUI: How to parse String Array into text

Question

I've tried following this and this and this, but I'm having issues getting the data from a string array.

I have my state set as

 businessHours = : [
    "Monday: 7:00 AM – 7:00 PM",
    "Tuesday: 7:00 AM – 7:00 PM",
    "Wednesday: 7:00 AM – 7:00 PM",
    "Thursday: 7:00 AM – 7:00 PM",
    "Friday: 7:00 AM – 7:00 PM",
    "Saturday: 7:00 AM – 7:00 PM",
    "Sunday: Closed"
 ]

This only gets me the first element from the array

ForEach(businessHours.indices) {
    Text(self.businessHours[$0])
}

This fails

ForEach(businessHours.indices) {
    Text(self.businessHours)
}

This works in the console

for businesshour in businessHours {
print("Hours: \(businesshour).")
}

What am I doing wrong here?

I'm not going to be able to do this without providing my API key — Robert

You may use the JSON response you receive from the server. No need for the API key. — pawello2222

There is a much simpler way..

When you have an array where the values are separated by ", " you can divide the array with this comma symbol

For Example: I have a user model with food. Food is an array, which looks similar like this:

user.food = ["Banana", "Strawberry", "Apple"]

You noticed: Every item is separated by the comma.

Now you can simply use

Text(user.food.joined(separator: ", "))
   .multilineTextAlignment(.trailing)
   .padding()

Et voilá :)

Here is a demo that works. Tested with Xcode 12 / iOS 14

struct DemoView: View {
    let businessHours = [
         "Monday: 7:00 AM – 7:00 PM",
         "Tuesday: 7:00 AM – 7:00 PM",
         "Wednesday: 7:00 AM – 7:00 PM",
         "Thursday: 7:00 AM – 7:00 PM",
         "Friday: 7:00 AM – 7:00 PM",
         "Saturday: 7:00 AM – 7:00 PM",
         "Sunday: Closed"
     ]

    var body: some View {
        VStack {
            ForEach(businessHours.indices) {
                 Text(self.businessHours[$0])
            }
        }
    }
}

Oh this is interesting. I did some more testing and that does work, but if the data is dumped into a State such as ` @State var businessHours = []` from an API call I get my original behavior. When I print businessHours I get the following in the console

["Monday: 7:00 AM – 7:00 PM", "Tuesday: 7:00 AM – 7:00 PM", "Wednesday: 7:00 AM – 7:00 PM", "Thursday: 7:00 AM – 7:00 PM", "Friday: 7:00 AM – 7:00 PM", "Saturday: 7:00 AM – 7:00 PM", "Sunday: Closed"]

Well... then I assume the issue is in the code you assign values from API to state.

Sorry that isn't making sense since when I print businessHours to the console all the data is present, but it's only taking the first index.

I also found that if I use Text("\(businessHours)" as String) the data is dumped into text

I figured it out.

(0..<businessHours.count, id: \.self) { index in
       Text(self.businessHours[index])
}
