How to Print a Dictionary in Swift - Step by Step Examples

How to Print a Dictionary in Swift ?

Answer

To print a dictionary in Swift, you can use a `for` loop to iterate over the key-value pairs and print each pair using the `print` function.

✐ Examples

1 Printing a Dictionary with Integer Keys and String Values

We can print a dictionary in Swift where the keys are integers and the values are strings. This example demonstrates how to iterate over a dictionary and print its contents.

For example,

We start by declaring and initializing a dictionary named myDictionary with integer keys and string values.
We use a `for` loop to iterate over the key-value pairs in the dictionary.
We print each key-value pair using the `print` function.

Swift Program

var myDictionary: [Int: String] = [
    1: "One",
    2: "Two",
    3: "Three"
]

// Print the dictionary contents
print("Dictionary contents:")
for (key, value) in myDictionary {
    print("Key: \(key), Value: \(value)")
}

Output

Dictionary contents:
Key: 1, Value: One
Key: 2, Value: Two
Key: 3, Value: Three

2 Printing a Dictionary with String Keys and Double Values

We can print a dictionary in Swift where the keys are strings and the values are doubles. This example demonstrates how to iterate over a dictionary and print its contents.

For example,

We start by declaring and initializing a dictionary named myDictionary with string keys and double values.
We use a `for` loop to iterate over the key-value pairs in the dictionary.
We print each key-value pair using the `print` function.

Swift Program

var myDictionary: [String: Double] = [
    "A": 1.1,
    "B": 2.2,
    "C": 3.3
]

// Print the dictionary contents
print("Dictionary contents:")
for (key, value) in myDictionary {
    print("Key: \(key), Value: \(value)")
}

Output

Dictionary contents:
Key: A, Value: 1.1
Key: B, Value: 2.2
Key: C, Value: 3.3
