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)")
}
// 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)")
}
// 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
last_name = Kargopolov
first_name = Sergey
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.
