使用swift在字典中迭代

let dictionary = ["key1": "value1", "key2": "value2", "key3": "value3"]

for (key, value) in dictionary {
    print("Key: \(key), Value: \(value)")
}

let dictionary = ["key1": "value1", "key2": "value2", "key3": "value3"]

dictionary.forEach { (key, value) in
    print("Key: \(key), Value: \(value)")
}

let dictionary = ["key1": "value1", "key2": "value2", "key3": "value3"]

// 迭代字典的键
for key in dictionary.keys {
    print("Key: \(key)")
}

// 迭代字典的值
for value in dictionary.values {
    print("Value: \(value)")
}
