NSDictionary* tsikzoe = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfFile:dataPath]options:kNilOptions error:&err];
Your JASON is an array in this case, so you will need to access one of the two elements in this array, which would be a dictionary.
A dictionary JSON will have this format
{
"employees": [ //right here!
{ "firstName":"John" , "lastName":"Doe" },
{ "firstName":"Anna" , "lastName":"Smith" },
{ "firstName":"Peter" , "lastName":"Jones" }
]
}
An Array JSON will have this format
{
[ //notice the difference.
{ "firstName":"John" , "lastName":"Doe" },
{ "firstName":"Anna" , "lastName":"Smith" },
{ "firstName":"Peter" , "lastName":"Jones" }
]
}
