1 is Linux only change, Swift 5 | By default, the function terminates the line it prints by adding a line break |

Using explicitly sized types in these situations helps to catch any accidental value overflows and implicitly documents the nature of the data being used | Type safety helps you catch and fix errors as early as possible in the development process |
Because makeASandwich can throw an error, the function call is wrapped in a try expression.
13Instead, this example calls UInt16 one to create a new UInt16 initialized with the value of one, and uses this value in place of the original:• On a 32-bit platform, Int is the same size as Int32 | This means you can use as many assertions as you want during your development process, without impacting performance in production |
---|---|
Nor can you change a constant into a variable or a variable into a constant | You can change the value of an existing variable to another value of a compatible type |
You can omit the assertion message—for example, when it would just repeat the condition as prose | You can use a tuple to return multiple values from a function as a single compound value |
