How can I remove quotes from String on Swift?

You can simply use

Swift 1

var str: String = "\"Hello\""

print(str) // "Hello"

print(str.stringByReplacingOccurrencesOfString("\"", withString: "")) // Hello

Update for Swift 3 & 4

print(str.replacingOccurrences(of: "\"", with: "")) // Hello

"\"Hello\"".stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "\""))
