The preceding code assumes an array called listArray. Then it uses a ForEach loop with .filter to search for the text the user typed into the search bar (stateVariable). This filters out the items in the array and displays the results in the Text view using an arbitrarily named variable called “name.”

To see how to search for items in a List view, follow these steps:1.

Create a new iOS App project and name it SearchApp.

2.

Click on the ContentView file in the Navigator pane.

3.

Add the following State variable and array under struct ContentView: View like this: @State var searchText = ""

let petArray = ["Cat", "Dog", "Fish", "Donkey", "Canary", "Camel", "Frog"]
