Trimming Substrings from String Swift/SwiftUI

Let’s say I have the following strings:

"Chest Stretch (left)"
"Chest Stretch (right)"

How can I use SwiftUI to output only:

"Chest Stretch"

I thought this may be a possible duplicate of swift – substring from string.

However, I am seeking a way to do this inside var body: some View within an if conditional expression.

>Solution :

A possible way is Regular Expression

let string = "Chest Stretch (left)"
let trimmedString = string.replacingOccurrences(of: "\\s\\([^)]+\\)", with: "", options: .regularExpression)

The found pattern will be replaced with an empty string.

The pattern is:

• One whitespace character \\s
• An opening parenthesis \\(
• One or more characters which are not a closing parentheses [^)]+
• and a closing parenthesis \\)

Or simpler if the delimiter character is always the opening parenthesis

let trimmedString = String(string.prefix(while: {$0 != "("})).dropLast()

Or

let trimmedString = string.components(separatedBy: " (").first!
