Xcode – How can I find repeated words and separate from sentences?

For example. I have string value like this :

var str = "asdImverygreatfullasdandeverythingwillbegoodandIwillbehappy"

there is ‘asd’ and ‘and’ these two words repeat between sentences. I want to find these two words and remove from str. Is that possible?

Desire output will be :

str = "ImverygreatfulleverythingwillbegoodIwillbehappy"

     str = str.replacingOccurrences(of: "and", with: "")

    An efficient way is to replace the substrings with help of Regular Expression

    let str = "asdImverygreatfullasdandeverythingwillbegoodandIwillbehappy"
let cleaned = str.replacingOccurrences(of: "a(s|n)d", with: "", options: .regularExpression)

    "a(s|n)d" means find both "asd" and "and"
