So I'm not sure why I getting this error, if anyone have idea then please help me.

Answer 1

Increase your call timeout. The request takes time to execute, and your request times out before the request is completed. If you're using NSURLSessions, this is the code.

let sessionConfig = URLSessionConfiguration.default
sessionConfig.timeoutIntervalForRequest = 40.0
sessionConfig.timeoutIntervalForResource = 60.0
let session = URLSession(configuration: sessionConfig)
