Value of type 'String' has no member 'stringByTrimmingCharactersInSet'

Question

After converting my project to swift 3, I get the following Value of type \'String\' has no member \'stringByTrimmingCharactersInSet\' error on the first line w

Answer 1

The new syntax is like this:

var cString = hex.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines).uppercased()

As a suggestion, you don't need to specify that cString is a String, as this is assumed with the value you are assigning to it.

Answer 2

Read the Swift 3 documentation; the new Swift 3 API is:

func trimmingCharacters(in set: CharacterSet) -> String

https://developer.apple.com/reference/swift/string/1643030-trimmingcharacters

Answer 3

You can try this as well.

let trimmedString = hex.trimmingCharacters(in: CharacterSet.whitespaces)

Answer 4

And for an Int and Float how can I code it ?

    private var currentTotal_passengers: Int = 0 {
    didSet {
        currentTotal_passengers = currentTotal_passengers.trimmingCharacters(in: CharacterSet .whitespacesAndNewlines)
    }
}
