Swift 3.0 does not support `var` in function/closure parameter list. For some reason Swift parser didn't catch this as syntax error, I'd suggest you to report a bug on bugs.swift.org.
This version works: let string = "a simple test" if (string.characters.count > 0) { let words = string.components(separatedBy: " ") let headline = words.map { wordParam -> String in //<<< immutable var word = wordParam //<<< assign to mutable instance let firstCharacter = word.remove(at: word.startIndex) return "\(String(firstCharacter).uppercased())\(word)" }.joined(separator: " ") } _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
