In a Swift dictionary, we can search for an element that is either a key or value with the help of contains() function. The contains() function will return a boolean value which represents whether the specified element(key or value) is found or not. Syntax dict.contains{$0.key == “KeyName”} Here, dict is the dictionary. The contains() function returns a boolean value which represents the result. Here we pass a closure in the function which will check if the current key is equal to the specified key or not and then return the result accordingly. Algorithm Step 1 − Create a ... Read More
