How do you Parse an Array of Dictionaries in Swift?

Question

I'm new to swift and I am having difficulty parsing an array the array looks like this

MyArray [ [0]9keyValuePairs [1]9keyValuePairs ]

I would like to add "MyArray.(0).ValueForKey:"Name" " to a UITableViewCell, but I can't quite figure out the correct syntax.

Assuming this is what you mean [[Key:Value]] you would do yourArray[index][key] to get the value — boidkan

Also, you can read up on collection types for swift. developer.apple.com/library/ios/documentation/Swift/Conceptual/… — boidkan

How is your array declared? If it is a array of something generic, ie [AnyObject] then you need to tell the type checker that the object in the array is a dictionary by casting it, otherwise you wont be able to access it as a dictionary.

If it is explicitly declared as an array of dictionaries ie [[String:AnyObject]] , then you just need to access the element in the array that you want, and then access the dictionary element you are interested in.

array[0] //how to get something out of an array
dictionary[key] //how to get something out of a dict
array[0][key] //how to get something out of an array of dicts

// if your array contents need to be cast, safely cast it using optional unwrapping 
if let dict = array[0] as? [String:AnyObject] { 
    dict[key]
}
