Using Russian characters in URL query

I want to load a URL in UIWebView using the value of UITextField in the URL query:

let texts = SearchBox.text!
let searchurl = "http://sngpoisk.ru/search-location/?search_keywords=\(texts)&search_location=&place_location=&latitude=&longitude="
let urls = NSURL(string:searchurl)
let ret = NSURLRequest(URL:urls!)
Browser!.loadRequest(ret)

But when texts contains Russian characters, an error occurs:

EXC_BAD_INSTRUCTION (code=EXC_1386_INVOP , subcode=0x0)

The reason of the runtime error is you unwrap an optional instance of the NSURL, which is actually nil.

The reason of urls is nil is searchurl string contains invalid characters (outside of the 7-bit ASCII range). To be used in URL that characters should be percent-encoded.

Swift 2 (I guess you are using that version):

let encodedTexts = texts.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
if let encodedTexts = encodedTexts {
    let searchurl = "http://sngpoisk.ru/search-location/?search_keywords=\(encodedTexts)&search_location=&place_location=&latitude=&longitude="
    let urls = NSURL(string:searchurl)
    if let urls = urls {
        let ret = NSURLRequest(URL:urls)
        Browser!.loadRequest(ret)
    }
}

Swift 3:

let encodedTexts = texts.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)
if let encodedTexts = encodedTexts {
    let searchurl = "http://sngpoisk.ru/search-location/?search_keywords=\(encodedTexts)&search_location=&place_location=&latitude=&longitude="
    let urls = URL(string:searchurl)
    if let urls = urls {
        let ret = URLRequest(url:urls)
        Browser!.loadRequest(ret)
    }
}

I find Thank you very much

let texts = Searchd.text!
    let encodedTexts = texts.stringByAddingPercentEncodingWithAllowedCharacters( NSCharacterSet.URLQueryAllowedCharacterSet())
    if let encodedTexts = encodedTexts {
        let searchurl = "http://sngpoisk.ru/search-location/?search_keywords=\(encodedTexts)&search_location=&place_location=&latitude=&longitude="
        let urls = NSURL(string:searchurl)
        if let urls = urls {
            let ret = NSURLRequest(URL:urls)
            Browser!.loadRequest(ret)
        }
    }
