Hi, I am using Buzztouch 3.0 to develop my apps. One of my iOS app is now displaying an error that "There was a problem reading the required data". Previously it was working fine.

Check your characters and quote marks to ensure they are valid. Your JSON may 'look' valid, and it may even get through jsonlint. But the wrong quote mark will error out, as well as certain odd characters. Good Luck! Cheers! -- Smug

Hi, But this app was working two days ago and no changes were made. The Android version of this app is also working fine. Please find the screenshot my screen http://jmp.sh/v/jApBnC42e2eGslV5Iv71

Smug, has given you wise words. The following extract is the clue to where I would start looking: 2015-12-30 12:03:30.049 sanantoniorealestateterilucas[58724:3555502] BT_application: ERROR parsing JSON in validateApplicationData: ( "Error Domain=org.brautaset.JSON.ErrorDomain Code=5 "Unescaped control character '0xa'" UserInfo={NSLocalizedDescription=Unescaped control character '0xa'}",

I had this error two days ago... Turns out that there was one additional space (blank character) in the JSON file. Did you run your JSON file through the json lint checker like this one here: http://jsonlint.com/ Something is wrong with the JSON file, so check it out.
