Google Authentication - User agent gives error on WebView (Nylas api)

Question

We are using Nylas api to get Access token for different type of Email account like Gmail, Outlook.. But We couldn't authenticate for Gmail.

        let myURL = URL(string: getNylasAuthUrl())
        let userAgent = getUserAgentParams()
        webView.customUserAgent = userAgent
        let myRequest = URLRequest(url: myURL!)
        webView.load(myRequest)

got below error

Finally found a way, by setting User-Agent, we could do authentication for gmail from post

Tried below User-agents but didn't help

let userAgent =  "Mozilla/5.0 (Apple \(Utils.getDeviceModel()) ) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36"
let userAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36"
let userAgent = "Mozilla/5.0 (Google) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36"

Finally, I found the working user-agent.

    let userAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_2 like Mac OS X)
AppleWebKit/603.1.30 (KHTML, like Gecko) Mobile/14F89 Safari/602.1"

If you want to Google auth via Webview, use this user-agent especially for getting access token.
