为了在 Swift 中实现简单的“消除 trol”功能，我们可以根据“ trol”关键字从数组中过滤评论。以下是一个简洁的示例： swift import Foundation func eliminateTrolls(from comments: [String], with keywords: [String]) -> [String] { let lowercasedKeywords = keywords.map { $0.lowercased() } return comments.filter { comment in !lowercasedKeywords.contains(where: { comment.lowercased().contains($0) }) } } let comments = [ "I love this post!", "You're the worst! Get a life, trol!", "This is so insightful!", "Shut up and go away, nobody likes you.", "What a great article! Thanks for sharing." ] let trollKeywords = ["trol", "worst", "shut up", "go away", "nobody likes you"] let filteredComments = eliminateTrolls(from: comments, with: trollKeywords) print("Filtered Comments:") filteredComments.forEach { print($0) }

关键点：

1. 函数：eliminateTrolls 根据 trol 关键字过滤评论。
2. 不区分大小写：关键字转换为小写。
3. 使用：定义评论和关键字的数组，并应用过滤函数。这为 Swift 中的 trol 消除提供了基本框架。
