I have problem with following code: String URL works fine in browser, but cant create URL from it.

    let stringURL = "http://dev.rationaletech.com:8063/Images/Offers/1/20%25-off-at-gloria-jean’s-coffee-6b62e43e-ba2b-4c9c-9f70-8b24e2a514a0.jpg"
    let url = URL(string:stringURL)

url property is nil after.

I have realized that problem is caused by ’ character inside link.

Any suggestions?

Update:

I have done next:

    let charactesSet = CharacterSet(charactersIn: "#<>^`{|}").inverted
    if let stringUrl = stringURL.addingPercentEncoding(withAllowedCharacters: charactesSet){
        let url = URL(string:stringURL)
    }

where charactesSet is URLHostAllowedCharacterSet "#%/<>?@\^`{|}" without %. And now i have: http://dev.rationaletech.com:8063/Images/Offers/1/20%25-off-at-gloria-jean%E2%80%99s-coffee-6b62e43e-ba2b-4c9c-9f70-8b24e2a514a0.jpg which works. I dont like this solution, will talk to server side. tnx

Tip: `jean’s-coffee` => `jeans-coffee` make it works (it's not nil, I'm not saying if the URL is valid not 404 or not). You might want to "percent escape" characters (that's some keyword to search). – Larme Feb 09 '18 at 13:51
Thank you @Larme – sladjann Feb 09 '18 at 14:07

Thanks everyone, it looks like server returned half encoded url (encoded % and skiped ’). – sladjann Feb 09 '18 at 16:42
