Selecting a particular item from an array

toddrmyers11 · January 18, 2022, 7:39pm

Please help. The code is hard to show but basically I have made a view of a list of buttons from an array in my json file. My problem is that whenever I change the property of the button in my view (like the color) it changes the color of every button. And I can’t assign an action to the button individually. Is there a way that I can use the index number from the items in the array to highlight an individual button and to have each button execute individual action when pressed?

import SwiftUI

struct PE: View {
  
    var spacing: CGFloat = 8
    var padding: CGFloat = 8
    var wordCount: Int = 75
    var alignmentIndex = 0

    var poswords: [String] {
        Array(p.posPE.prefix(wordCount))
    }
    var negwords: [String] {
        Array(p.negPE.prefix(wordCount))
    }

    let alignments: [HorizontalAlignment] = [.leading, .center, .trailing]

    var alignment: HorizontalAlignment {
      alignments[alignmentIndex]
    }
  
   @State private var note: String = ""
  
   
    var p:Pizza
    var body: some View {
        Text(p.name)
            .font(.largeTitle)
            .multilineTextAlignment(.leading)
            .padding(.vertical)
