I am trying to simulate (mocking it) a server using Charles. I found out that Charles has something called "Map Local..." which allows me to reply to a client using files I have stored locally.
The files I am pointing to have been stored by right clicking in the Charles Sequence list and choosing "Save Response...".
However when testing this with my iOS app I get the following error message:
Failed to get areas: Error Domain=AFNetworkingErrorDomain Code=-1016 "Expected content type {(
"text/json",
"application/json",
"text/javascript"
)}, got text/plain"
So somehow I am not sending the response with the correct header information for Content type. Is there a way of telling Charles that the response is JSON? A possible problem is that the files stored only contains the JSON data and not any header.

json on my Desktop. Map Local: Now we go back to Charles map local and clicking Add and we put the host we want to switch-out from, the path, whether it's http or https. [Time-Saver: If you just paste the whole URL into host it will auto-populate the relevant fields for you.] Then in Map To you want to define your .
You can choose a URL that contains the desired response or either create a mock one (by using tools such as "mocky.io"). 2) You can use "Map Remote" and do the same - choose the network you would like to modify with the URL that contains the response you desire.
You need to add a rewrite rule in Charles to change the Content-Type header back to application/json.
Map Local will only give a text/plain Content-Type.
To do this, go to Tools > Rewrite... > Add.
Add all the locations that you are mapping locally and then for the rules, add one that looks like the following:
I would never recommend adjusting your code just for Charles as this defeats the point of testing your web services if you can't replicate them exactly.
