Unable to parse the exact error from ParseError

[kennic]

New Issue Checklist

• I am not disclosing a vulnerability.
• I am not just asking a question.
• I have searched through existing issues.
• I can reproduce the issue with the latest versions of Parse Server and the Parse Swift SDK.

Issue Description

The current SDK returns all errors with ParseError which can not be used to determine the exact error details to show on the UI.

Steps to reproduce

• Disconnect the internet on your device (Turn on Airplane Mode)
• Try to call any CloudCode function

Actual Outcome

You will get this ParseError:

(lldb) po error
ParseError code=-1 error=Unable to connect with parse-server: Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline." UserInfo={_kCFStreamErrorCodeKey=50, NSUnderlyingError=0x282733570 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 "(null)" UserInfo={_NSURLErrorNWPathKey=unsatisfied (No network route), _kCFStreamErrorCodeKey=50, _kCFStreamErrorDomainKey=1}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <27703A59-4B71-4320-B775-0560BC43DFDB>.<6>, _NSURLErrorRelatedURLSessionTaskErrorKey=(

), NSLocalizedDescription=The Internet connection appears to be offline., NSErrorFailingURLStringKey=https://host/functions/FunctionName, NSErrorFailingURLKey=https://host/functions/FunctionName, _kCFStreamErrorDomainKey=1}
  - code : ParseSwift.ParseError.Code.unknownError
  - message : "Unable to connect with parse-server: Error Domain=NSURLErrorDomain Code=-1009 \"The Internet connection appears to be offline.\" UserInfo={_kCFStreamErrorCodeKey=50, NSUnderlyingError=0x282733570 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 \"(null)\" UserInfo={_NSURLErrorNWPathKey=unsatisfied (No network route), _kCFStreamErrorCodeKey=50, _kCFStreamErrorDomainKey=1}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <27703A59-4B71-4320-B775-0560BC43DFDB>.<6>, _NSURLErrorRelatedURLSessionTaskErrorKey=(\n    \"LocalDataTask <27703A59-4B71-4320-B775-0560BC43DFDB>.<6>\"\n), NSLocalizedDescription=The Internet connection appears to be offline., NSErrorFailingURLStringKey=https://host/functions/FunctionName, NSErrorFailingURLKey=https://host/functions/FunctionName, _kCFStreamErrorDomainKey=1}"
  - otherCode : nil

You'll get these details:

(lldb) po error.domain
"ParseSwift.ParseError"

(lldb) po error.code
1

(lldb) po error.localizedDescription
"ParseError code=-1 error=Unable to connect with parse-server: Error Domain=NSURLErrorDomain Code=-1009 \"The Internet connection appears to be offline.\" UserInfo={_kCFStreamErrorCodeKey=50, NSUnderlyingError=0x282733570 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 \"(null)\" UserInfo={_NSURLErrorNWPathKey=unsatisfied (No network route), _kCFStreamErrorCodeKey=50, _kCFStreamErrorDomainKey=1}}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <27703A59-4B71-4320-B775-0560BC43DFDB>.<6>, _NSURLErrorRelatedURLSessionTaskErrorKey=(\n    \"LocalDataTask <27703A59-4B71-4320-B775-0560BC43DFDB>.<6>\"\n), NSLocalizedDescription=The Internet connection appears to be offline., NSErrorFailingURLStringKey= host/functions/FunctionName, NSErrorFailingURLKey=https://host/functions/FunctionName, _kCFStreamErrorDomainKey=1}"

We can not get the exact error domain NSURLErrorDomain, code -1009 with the message The Internet connection appears to be offline to display it on the UI correctly, but only ParseSwift.ParseError code 1 all the time.

Expected Outcome

We need an originalError variable in ParseError so we can check what was the exact error that caused the problem, not just ParseSwift.ParseError code 1
