> Key: THRIFT-3401
> URL: https://issues.apache.org/jira/browse/THRIFT-3401
> Project: Thrift
> Issue Type: Bug
> Components: Cocoa - Compiler
> Affects Versions: 1.0
> Environment: OS X 10.9 and 10.10
> Reporter: Steve Yegge
> Assignee: Kevin Wooten
> Priority: Critical
> Fix For: 1.0

> Original Estimate: 72h

> Nested Thrift collections produce nested generics in Objective-C.
> Unfortunately, Objective-C generics do not appear to support type nesting.
> For instance,
> 1: list<list<string>> foo
> generates an Objective-C declaration like this
> @property (strong, nonatomic) NSMutableArray<NSArray<NSString *>> * foo;
> which results in an XCode compile error: Type argument 'NSArray<NSString *>'
> is neither an Objective-C object nor a block type
> The only workaround is to edit the generated code to remove the nested type
> specifiers.
> Until Objective-C supports nesting generic types, the Thrift cocoa compiler
> should limit the type nesting to at most one level -- NSMutableArray<NSArray>
> is legal, for instance. Alternately, an easier solution might be to add a
> flag that disables the generation of generic types for cocoa.
