How to index into Array of Dictionaries - ios

Question

I have an object that looks like this in the console. It seems like an array with a dictionary inside. How can I get to the address field?
Optional((
{
address = "xxxxxxx#gmail.com";
verified = 1;
}
))
The object comes from this object:
<METDocument key: <collection: users, ID: KTsCySacEAiz3eDnf>, fields: {
emails = (
{
address = "xxxxxxx#gmail.com";
verified = 1;
}
);
profile = {
address = {
city = Oslo;
country = nor;
lineOne = "address";
lineTwo = "";
zip = 0264;
};
birthdate = "1985-09-01 23:00:00 +0000";
card = {
last4 = 4242;
verified = 1;
};
filledOut = 1;
gender = Male;
name = {
first = "Elon";
last = "Musk";
};
phone = 911;
validated = 1;
};
}>
I access the emails key by this method:
let emails = users.allDocuments[0].valueForKey("emails")

Answer 1

The content of the object is an optional array.
There are two options:
Safe access:
if let emails = users.allDocuments[0].objectForKey("emails") where emails.count > 0 {
if let address = emails[0]["address"] as? String {
print(address)
}
}
If it's guaranteed that the dictionary in the array and the key address exists:
let emails = users.allDocuments[0].objectForKey("emails")!
let address = emails[0]["address"] as! String
