Its combination of safety and capabilities. Our goals for Swift are ambitious. We can’t wait to see what you create with it.

f( 1.0 ); } } // namespace N1 int main() { } // Ill-formed, no conversion available // Ill-formed, no conversion available N1::g(); N1::h(); Function (2) hides function (1)(Un-)Qualified Name candidates that match the number of given arguments and that could be called (with or without conversion). 2. Find the best match from the list of viable candidates: Determine a single function that // Default arguments // Less parameters than arguments // More parameters than arguments // No conversion available // Matching constraints // Ellipsis argument // Violated constraintsOverload Resolution

implicit conversion 22Overload Resolution ● Type Conversions ○ example of an implicit conversion char str[] = "ABC"; int data = str[0]; // data will equal 65 ○ explicit conversion ■ static_cast another type of explicit conversion called an functional cast if (std::string(“root”) == current_directory) { // do something } 23Overload Resolution ● Standard Conversion Categories ○ exact match match (1) ■ no conversion is required ○ lvalue transformations (2) ■ lvalue to rvalue conversion (based on value categories) ■ array to pointer conversion ■ function to pointer conversion ○ qualification

conversions…  Calling f(int)requires no conversion at all.  It’s an exact match.  Calling f(long int)requires converting intinto “long int”.  This is an integral conversion.  Calling f(char *)requires converting converting intinto “pointer to char”.  This is a pointer conversion. 19 Exact Matches Always Win  The compiler prefers “cheap” conversions.  Exact matches are the cheapest of all.  Thus, f(0)calls: 23 Conversion Rank no conversion Exact Match “cheap” array-to-pointer conversion qualification conversion etc. integral promotion Promotion floating-point promotion integral conversion Conversion
