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+?

Removing the specific character To remove the specific character from a string, we can use the built-in remove() method in Swift. The remove() method takes the character position as an argument and removed it from the string.
The first and most commonly used method to remove/replace any substring is the replace() method of Java String class. The first parameter is the substring to be replaced, and the second parameter is the new substring to replace the first parameter.
Swift String dropLast() The dropLast() method removes the last character of the string.
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])
