Output error: cannot convert value of type '(String, String)'Įrror: value of tuple type '(String, String)' has no member 'remove' For example, var company = ('Programiz','Apple') We cannot add or remove elements from a tuple in Swift. To access the first element of the nested tuple. Since the third element of the is also a tuple, we have used alphabets.3.0 Here, we have first accessed the third element of the alphabets tuple. In the above example, notice the line, print(alphabets.3) This is called a nested tuple.Įxample: Nested Tuple var alphabets = ('A', 'B', 'C', ('a', 'b', 'c')) Here, we have a tuple ('a', 'b', 'c') as the third element of the alphabets tuple. In Swift, we can create a tuple as an element of another tuple.

Note: It is the best practice to use the named tuples as it makes our code more readable. notation and the provided names to access the corresponding values of the tuple. We have used the index number: product.0 and product.1 to access tuple elements. In the above example, we have created a tuple named product with two values. For example, // access the first elementĮxample: Swift Tuple // create tuple with two elements We use the index number to access tuple elements. Like an array, each element of a tuple is represented by index numbers ( 0, 1. Here, product is a tuple with a string value Macbook and integer value 1099.99. For example, var product = ('MacBook', 1099.99)

In Swift, we use the parenthesis () to store elements of a tuple. Suppose we need to store information about the name and price of a product, we can create a tuple with a value to store name (string) and another value to store price (float) And, each value inside a tuple can be of different data types.

In Swift, a tuple is a group of different values.
