To iterate over the entries (key-value pairs) in a dictionary in Swift, you can use a `for-in` loop to loop through the dictionary. This allows you to access both the key and the value of each entry.
We can iterate over the entries in a dictionary in Swift using a `for-in` loop. This example demonstrates how to loop through the entries of a dictionary and print each key-value pair.
For example,
myDictionary
with integer keys and string values.var myDictionary: [Int: String] = [
1: "One",
2: "Two",
3: "Three"
]
// Iterate over the entries in the dictionary
print("Entries in the dictionary:")
for (key, value) in myDictionary {
print("Key: \(key), Value: \(value)")
}
Entries in the dictionary: Key: 1, Value: One Key: 2, Value: Two Key: 3, Value: Three
We can iterate over the entries in a dictionary in Swift using a `for-in` loop and perform operations on the values. This example demonstrates how to loop through the entries of a dictionary, modify the values, and print each key-value pair.
For example,
myDictionary
with integer keys and string values.var myDictionary: [Int: String] = [
1: "One",
2: "Two",
3: "Three"
]
// Iterate over the entries in the dictionary and modify values
print("Modified entries in the dictionary:")
for (key, value) in myDictionary {
let modifiedValue = value.uppercased()
print("Key: \(key), Value: \(modifiedValue)")
}
Modified entries in the dictionary: Key: 1, Value: ONE Key: 2, Value: TWO Key: 3, Value: THREE
In this tutorial, we learned How to Iterate over Entries (Key-Value Pairs) in a Dictionary in Swift language with well detailed examples.
