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.
