stringByReplacingOccurencesOfString() for Swift 3.0

Question

I'm having a problem when using stringByReplacingOccurencesOfString() into the latest version of Xcode 8.2 Beta. When using the function, Xcode is showing that the value type of string has no member.

var clockworkSmsUrl = "https://api.clockworksms.com/http/send.aspx?"
                       + "key=123456789abcd"
                       + "to="
                       + usersNumber!
                       + "&content="
                       + usersTextMessage!

clockworkSmsUrl.stringByReplacingOccurrencesOfString(" ", withString: "+")
var clockworkSmsURLconvert = NSURL(string: clockworkSmsUrl)

Any ideas?

Answer 1

You can fix your snippet using ...

clockworkSmsUrl.replacingOccurrences(of: " ", with: "+")

Swift 3 changed the way how objc APIs are imported.

Please note that there are some issues with the code you posted:

• the result of replacingOccurrences is discarded.
• there are more characters to be escaped.
• URLCompontents exposes safer ways to construct URLs.
