Answers for "tuple in swift"

tuple in swift

//Take this example

var sampleTuple = (element1, element2 ... (//for as many elements as needed))
  
//Now lets say we want to print the first element of the sampleTuple, we would do this
  
print(sampleTuple.0)
  
//Here, we can treat the tuple as some sort of an array.
//In this case, the 0 refers to the 1st "element" of the tuple
//Thus, it will print out the first element, or in this case, element1
  
//The next example:
var sampleTuple = (element1: value1, element2: value2)

//The : in this case refers to the declaration of the elements... basically:
//var element1 = value1
//(If we do this, we won't be able to print out the name element1, but instead the values (value1 and value2)

print(sampleTuple.element1)

//This means that it will print sampleTuple, and then print the value assigned to the firsts element, element1
