How to Check if Two Dictionaries are Equal in Swift - Step by Step Examples

How to Check if Two Dictionaries are Equal in Swift ?

Answer

To check if two dictionaries are equal in Swift, you can use the equality operator `==`. This allows you to determine if the dictionaries contain the same key-value pairs.

✐ Examples

1 Checking if Two Dictionaries are Equal Using `==` Operator

We can check if two dictionaries are equal in Swift using the equality operator `==`. This example demonstrates how to declare and initialize two dictionaries, use the `==` operator to compare them, and print whether they are equal.

For example,

We start by declaring and initializing two dictionaries named firstDict and secondDict with integer keys and string values.
We use the `==` operator to compare the dictionaries.
We print whether the dictionaries are equal.

Swift Program

let firstDict: [Int: String] = [
    1: "One",
    2: "Two",
    3: "Three"
]

let secondDict: [Int: String] = [
    1: "One",
    2: "Two",
    3: "Three"
]

// Check if the dictionaries are equal using == operator
let areEqual = firstDict == secondDict

// Print whether the dictionaries are equal
if areEqual {
    print("The dictionaries are equal.")
} else {
    print("The dictionaries are not equal.")
}

Output

The dictionaries are equal.

2 Checking if Two Dictionaries are Not Equal

We can check if two dictionaries are not equal in Swift using the equality operator `==`. This example demonstrates how to declare and initialize two dictionaries, use the `==` operator to compare them, and print whether they are not equal.

For example,

We start by declaring and initializing two dictionaries named firstDict and secondDict with integer keys and string values.
We use the `==` operator to compare the dictionaries.
We print whether the dictionaries are not equal.

Swift Program

let firstDict: [Int: String] = [
    1: "One",
    2: "Two",
    3: "Three"
]

let secondDict: [Int: String] = [
    1: "One",
    2: "Two",
    3: "Four"
]

// Check if the dictionaries are not equal using == operator
let areEqual = firstDict == secondDict

// Print whether the dictionaries are not equal
if !areEqual {
    print("The dictionaries are not equal.")
} else {
    print("The dictionaries are equal.")
}

Output

The dictionaries are not equal.
