import Swift;

var var1:Int    = 10;
var var2:Float  = 10.24;
var var3:Bool   = true;

print("Size of var1  : ",MemoryLayout.size(ofValue: var1));
print("Size of var2  : ",MemoryLayout.size(ofValue: var2));
print("Size of var3  : ",MemoryLayout.size(ofValue: var3));

Output:

Size of var1  :  8
Size of var2  :  4

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here, we created three variables of different types. Then we found the size of created variables using the MemoryLayout.size() method and printed the result on the console screen.
