How to obtain values without key of dictionary?

Question

var dictionary: Dictionary = [\"title\" : \"Berlin\",
\"description\" : \"Berlin square\",
\"createdBy\": \"Mathias\",
\"coordinates\": [\"fddfh         


        

Answer 1

You can get these values without knowing this key: cast "coordinates" to the right dictionary type then use optional binding and the values property.

Example:

if let dict = dictionary["coordinates"] as? [String:[String:Double]],
        content = dict.values.first,
        latitude = content["latitude"],
        longitude = content["longitude"] {
    print(latitude)
    print(longitude)
}

As an update after your comments: all you need to do now is to adapt to different dictionary structures.

For your second dictionary, look how it is structured:

for (key, value) in dictionary2 {
    print(key)
    print(value)
    print("---")
}

The values you're looking for are not at the same level than the other ones we grabbed previously.

Adapt the solution I've already given: it's only a matter of hierarchy in the dictionary. In dictionary1 the unknown key was in "coordinates", but this one is at the root level.
