[Swift] If you want to use a URL that includes Japanese, use addingPercentEncoding.

I stumbled upon an API call without knowing it.

json-> swift type generation used quicktype

(Click here for the story of decoding failure when trying to get data from NewsAPI [Swift] A story that failed in decoding json acquired by News API and crushed it for half a day)

I had to use addingPercentEncoding when I wanted to fetch data from a URL containing Japanese in the API. image.png

So in the case of URL including Japanese, it should have been written as follows

let NewsApiURL="https://newsapi.org/v2/everything?q=\(keyword)&num=3&sortBy=latest&apiKey=\(myApiKey)"
let encodedURL = NewsApiURL.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed)

guard let url = NSURL(string: encodedURL!) else {
    print("Invalid URL.")

I gave it like this and it worked.
