Question

I have the following array:

var notebookCovers = [\"cover1\", \"cover2\", \"cover3\", \"cover4\", \"cover4\", \"cover6\", \"cover7\", \"cover8\", \"cover9\"         


        

Answer 1

You can try something like this,

var notebookCovers = ["cover1", "cover2", "cover3", "cover4", "cover4", "cover6", "cover7", "cover8", "cover9", "cover10"]
var tappedNotebooks: [String] = []
func tapping() {
    let notebook  =  notebookCovers[Int.random(in: 0...notebookCovers.count - 1)]
    if tappedNotebooks.contains(notebook){
        print("already exists trying again!")
        tapping()
    } else {
        tappedNotebooks.append(notebook)
        print("appended", notebook)
    }
    if tappedNotebooks == notebookCovers {
        tappedNotebooks = []
        print("cleared Tapped notebooks")
    }
}
