How to Convert a Dictionary to an Array of Values in Swift ?

Answer

To convert a dictionary to an array of values in Swift, you can use the `values` property of the dictionary and convert it to an array. This allows you to create an array containing all the values in the dictionary.

✐ Examples

1 Converting a Dictionary to an Array of Values Using `values` Property

We can convert a dictionary to an array of values in Swift using the `values` property. This example demonstrates how to declare and initialize a dictionary, use the `values` property to get the values, convert them to an array, and print the array of values.

For example,

We start by declaring and initializing a dictionary named myDictionary with integer keys and string values.
We use the `values` property to get the values from the dictionary.
We convert the values to an array.
We print the array of values.

Swift Program

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

// Convert the dictionary to an array of values
let valuesArray = Array(myDictionary.values)

// Print the array of values
print("Array of values:")
for value in valuesArray {
    print(value)
}

Output

Array of values:
One
Two
Three

2 Converting an Empty Dictionary to an Array of Values

We can convert an empty dictionary to an array of values in Swift using the `values` property. This example demonstrates how to declare and initialize an empty dictionary, use the `values` property to get the values, convert them to an array, and print the array of values.

For example,

We start by declaring and initializing an empty dictionary named myDictionary.
We use the `values` property to get the values from the dictionary.
We convert the values to an array.
We print the array of values.

Swift Program

var myDictionary: [Int: String] = [:]

// Convert the dictionary to an array of values
let valuesArray = Array(myDictionary.values)

// Print the array of values
print("Array of values:")
for value in valuesArray {
    print(value)
}

Output

Array of values:
