You can use the following line to get the desired array:

let array = myString2.components(separatedBy: " ").filter({ $0.compare($0.uppercased()) == .orderedSame })

Steps:

let arr = myString2.components(separatedBy: " ")
let filteredArray = arr.filter({ $0.compare($0.uppercased()) == .orderedSame })

Maybe you can use regular expression to achieve what you want.

var myString2 : String = "Cities of Illinois are CHICAGO PEORIA ROCKFORD"
let pattern = "\\b[A-Z]+\\b"
let regex = try! NSRegularExpression(pattern: pattern)
let matches = regex.matches(in: myString2, range: NSRange(0..<myString2.utf16.count))
let myArray = matches.map {String(myString2[Range($0.range, in: myString2)!])}
print(myArray) //->["CHICAGO", "PEORIA", "ROCKFORD"]
