 We require the programmer to supply headers for all Objective-C classes implemented in Haskell.  This enables the Objective-C compiler to do type checking and enables Interface Builder to recognises properties used as outlets.
 
+== Architecture ==
+
+Following the structure of the C FFI, the basic Objective-C FFI has two major components: (1) an extension of the Haskell language by new forms of `foreign` declarations and (2) a standard library.  The C FFI uses the `ccall` (and `stdcall`) calling convention for `foreign` declarations, whereas Objective-C uses the new `objc` calling convention.  The C-specific FFI library is `Foreign.C` (aka `CForeign`) and, for Objective-C, we use `Foreign.ObjectiveC`.
+
+In addition to the low-level FFI, higher-level libraries and tools may provide more convenient APIs.  In particular, the basic FFI makes no attempt to model Objective-C's class hierarchy and overloading of selectors in Haskell's type system.  This is the responsibility of higher-level libraries.
