I have encountered an obstacle in my iOS app where I need to store two arrays in a remote MySQL database using PHP and JSON. Despite multiple days of effort, I have been unsuccessful in converting the arrays from the iOS app into JSON code without causing the app to crash. The arrays are being populated by a QR code reader and an input field, with each array containing an equal number of items.
The current code snippet generates the following JSON:
json string = {"b":"[\n\n]","p":"[\n\n]"}Regardless of the changes I make, the app consistently crashes with errors such as 'Invalid top-level type in JSON write' or 'JSON text did not start with array or object'. Here is a version of the code I have been working on:
var productArray = [String]()
var amountArray = [String]()In this particular case, I am attempting to convert the arrays to JSON data and then back to strings for debugging purposes. Subsequently, I intend to cast them as dictionaries before serializing them and sending the JSON data via a POST request to a specified URL.
