To get more specific, I just made a quick pass through the Swift documentation, and came up with the following list of things where Swift adds useful functionality and/or features that we’ve been asking for for a long time: > Massive elimination of source duplication > Massive elimination of source boilerplate > Value types as a programming paradigm > Range operators (...) > Grapheme-based Unicode strings > Value-type strings > Value-type collections > Homogenous collection types (Obj-C has it now, more or less, but only because > of Swift) > Non-integer, non-literal switch case types > Patterns in switch cases > Explicit fall-through control of switch case types > Switch case “protected scopes” eliminated > Patterns in conditional cases > Where clauses > Label-targeted continue/break statements > SDK API availability checking > Overloadable functions > Multiple function return values > Parameter keywords in function calls > Default parameter values > Nested function declarations > Closure expression syntax improvements > Operator definitions > Operator functions > Enums are not ints > Enum cases can have associated values > Structs can have behavior (methods) > Deterministic rules for initializer methods (calling and inheritance) > Lazy stored properties > Property observers > Class properties > Mutability controls > Improved access controls > Safe method overridability > Override prevention > Enhanced initializer behavior and syntax > Automatic zombie detection > Capture lists for closures > Optionals > Optional chaining and unwrapping > Improved error handling model > Scope-exit cleanup actions > Safer type casting > Nested types > Safe class extensions > Protocols are types > Protocols can have default behavior (methods) > Constrained protocols > Generics That list doesn’t include benefits discussed elsewhere. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
