How to loop over a dictionary in Swift 5?

Question

In Swift 4 I could the code below worked but in Swift 5 I get the following error: Type 'Dictionary<String, String>.Values.Iterator' does not conform to protocol 'Sequence'

guard let userIds = users.values.makeIterator() else { return }

for userId in userIds {
    // User setup
}

What is the right way in Swift 5 now?

Answer 1

let dictionary: [String: Int] = ["a": 1, "b": 2]

for (key, value) in dictionary {
    print(key, value)
}

Answer 2

You can do simply

for (_, userId) in users {
    // User setup
}
