Keywords

The following words are treated as keywords in Swift and have special meaning:

RemObjects Swift Keywords

RemObjects Swift adds the following handful of keywords to support some Language Extensions in Apple's standard Swift implementation:

• __abstract — used for explicitly marking methods and types as abstract
• __await — .NET-style unwrapping of asynchronous calls
• __ensure — Class Contracts (Post-Conditions)
• __event — .NET-style Events
• __explicit — Cast Operators
• __external — External Library Imports
• __field — Declare a non-property field
• __implicit — Cast Operators
• __invariants — Class Contracts (Invariants)
• __lock
• __mapped – Mapped Types
• __old — Class Contracts (Post-Conditions)
• __out —
• __partial — Partial Classes
• __reintroduce
• __result — accessing the result of a method
• __require — Class Contracts (Pre-Conditions)
• __using — Using Statenents
• __yield — Iterators

Deprecated Exception Handling Keywords

These keywords were defined in RemObjects Swift 8.1 for Exception Handling. With[Swift 2.0 and later now supporting error handling officially, these are being deprecated in RemObjects Swift 8.2 and beyond, and will generate errors. They will be completely removed in subsequent versions of RemObjects Swift.

Please refer to the Exception and Error Handling topic for more details on the new error handling support in Swift 2.0 and RemObjects Swift 8.2 and later.

• __throw
• __try
• __catch
• __finally
