Answer 1

For checking if a string exists in a array with more Options(caseInsensitive, anchored/search is limited to start)

using Foundation range(of:options:)

let list = ["kashif"]
let word = "Kashif"


if list.contains(where: {$0.range(of: word, options: [.caseInsensitive, .anchored]) != nil}) {
    print(true)  // true
}

if let index = list.index(where: {$0.range(of: word, options: [.caseInsensitive, .anchored]) != nil}) {
    print("Found at index \(index)")  // true
}
