Does anyone know that?
Does anyone know where to find more detailed information about "String interpolation with a specifier/formatter"?
I know we can use string interpolation to format a number:
let pi = Double.pi
"\(pi, specifier: "%.2f")"
but I can't find any further information about this syntax, please help.
