Objective C provides a simpler way to declare and define accessor methods -using declared properties. The language provides features to declare a -property and to let compiler synthesize accessor methods. -

- -

The debugger lets developer inspect Objective C interfaces and their -instance variables and class variables. However, the debugger does not know -anything about the properties defined in Objective C interfaces. The debugger -consumes information generated by compiler in DWARF format. The format does -not support encoding of Objective C properties. This proposal describes DWARF -extensions to encode Objective C properties, which the debugger can use to let -developers inspect Objective C properties. -

- Proposal -

- - -
-

Objective C properties are always backed by an instance variable. The -instance variables backing properties are identified using -DW_AT_APPLE_property_name attribute. The instance variables with this -attribute may not have data location attributes. The location of instance -variables is determined by debugger only after consulting Objective C runtime. -
