Deleting Specific Substrings in Strings [Swift]

Question

I have a string var m = "I random don't like confusing random code." I want to delete all instances of the substring random within string m, returning string parsed with the deletions completed.

The end result would be: parsed = "I don't like confusing code."

How would I go about doing this in Swift 3.0+?

var m = "I random don't like confusing random code." let parsed = m.replacingOccurrences(of: "random", with: "") print(parsed). // I don't like confusing code. — Jaykant, Sep 30 '22 at 17:27

It is quite simple enough, there is one of many ways where you can replace the string "random" with empty string

let parsed = m.replacingOccurrences(of: "random", with: "")

Depend on how complex you want the replacement to be (remove/keep punctuation marks after random). If you want to remove random and optionally the space behind it:

var m = "I random don't like confusing random code."
m = m.replacingOccurrences(of: "random ?", with: "", options: [.caseInsensitive, .regularExpression])

@Harmish thanks a previous version in my playground had other punctuation marks hence the grouping – Code Different Feb 25 '17 at 22:38
