When i decode my result y got this error ResponseSerializationFailureReason, this happens in calls with accents, if i have not accent decode good.
I want to decode the service result

Given your description, whatever is generating the JSON is not using UTF-8. It's probably using Latin-1, or possibly one of the Windows code pages (but I'm betting Latin-1).

I'm learning Ruby and several tutorials introduce empty arrays and pushing values in them.
I googled "When are empty arrays used?" and there seems to be no web pages that talk about practical empty array usage.
My assumption is that empty arrays are used when arrays elements are unknown and external input provides the array elements. But I cannot think of any examples...
One example would be errors when they are encountered. e.g. in validation
errors[:base] << "Value must be an integer."

I am developing my own identity system for my ASP.Net 5 application, and I am currently looking for an efficient way to store my predefined error codes and their corresponding descriptions. Does anyone have any suggestions to my issue?
Use resource files: https://msdn.microsoft.com/en-us/library/windows/desktop/aa380599%28v=vs.85%29.aspx
They allow you to store the name of the error code, the error code and a description. Then use Properties.Resources to access them.

In acejs editor, we have a lot of build-in tokens, like string, command, and keyword. We can give different color and event handler according to tokens. Here, I wonder it's possible to create our own customer tokens.
Ace doesn't give any special meaning to tokens any string can be a token.

Maybe you mean how to concat strings?
for each code
[NSString stringWithFormat:#"www.testing.com/apps/star_json.php?code=%d", code]`
But this is an embarassingly badly posed question :D

Just to understand the basics of json parsing.
Things I would give a try:
Here someone has an answer for parsing JSON with Swift: How to parse a JSON file in swift?
Check this tutorial: http://jamesonquave.com/blog/developing-ios-apps-using-swift-tutorial-part-2/
See what others have done; you can check GitHub to find JSON parsers (example: https://github.com/stig/json-framework/). Then rewrite it in Swift.
Best wishes!
