Replace between substrings in swift? - swift

Question

I have a string like so:
let someString = "The (randomcharacters)(someknowncharacters) are playing in the NBA Finals"
I want to replace everything between the strings The and (some with the string Warriors. I have looked into using replacingOcurrences but that doesn't do what I want.

Answer 1

Here is another attempt using replaceOccurencesOf
func replace(_ original: String, between firstPart: String, and secondPart: String, with: String ) -> String {
let pattern = "\(firstPart) .* \(secondPart)"
let replacement = "\(firstPart) \(with) \(secondPart)"
return original.replacingOccurrences(of: pattern, with: replacement, options: .regularExpression)
}
It might need some adjustment in regard to handle space around the replaced word.
Example
let newString = replace("The Raptors are playing in the NBA Finals", between: "The", and: "are", with: "Warriors")

Answer 2

Using some "somerandomcharacters" would mean that you're essentially using a String as a (really shitty) vehicle to transport multiple pieces of data. But we already have a way to do that, with data types.
We can create a struct that holds the necessary information to describe a Basketball game. We can pass this data around throughout our app, with very easy access to its important components. Only our UI layer needs a string, so we only ever generate a string description of this struct at the very last moment, right at the UI layer.
struct BasketballTeam {
var name: String
}
struct BasketballGame: CustomStringConvertible {
let homeTeam: BasketballTeam
let awayTeam: BasketballTeam
let eventName: String
var description: String {
return "The \(homeTeam.name) are playing the \(awayTeam.name) in the \(eventName)."
}
}
let game = BasketballGame(
homeTeam: BasketballTeam(name: "Toronto Raptors"),
awayTeam: BasketballTeam(name: "Golden State Warriors"),
eventName: "NBA Finals"
)
print(game.description) // => The Toronto Raptors are playing the Golden State Warriors in the NBA Finals.
