I want to get the substring of all the characters after the last index of /
for example: "www.example.com/sfs3/dd/423"
desired output = 423
I've tried:
if let range = link.rangeOfString("/") { //does not give me the last index of / it gives me starting from the first / newlink = link.substringFromIndex(range.endIndex) } You could also use NSURL's -lastPathComponent:
let link = "www.example.com/sfs3/dd/423" if let url = NSURL(string: link) { let newLink = url.lastPathComponent // ... } This is probably the most bullet proof way if your input is a URL, be it from the web or from a local file.
With your syntax you can use the .BackwardsSearch option
if let range = link.rangeOfString("/", options: .BackwardsSearch) { let newlink = link.substringFromIndex(range.endIndex) } Alternatively
if let newlink = link.componentsSeparatedByString("/").last { print(newlink) } Edit: But I'd prefer the NSURL solution suggested by fabian.
