In this very short Swift tutorial, you will learn how to loop or iterate over a dictionary in Swift and print out key/value pairs.
Loop Through Dictionary
// Create a Dictionary with two elements var myDictionary = ["first_name": "Sergey", "last_name": "Kargopolov"] // Loop through dictionary and print key/value pair for (key,value) in myDictionary { print("\(key) = \(value)") }
If you run the above code in Xcode playground you will get the following result:
last_name = Kargopolov first_name = Sergey
Below is an image of my Xcode Playground with the above code snippet executed.
I hope you find this short Swift code snippet helpful.
