I'm interfacing to a 3rd party library that returns only a dispatch_data_t object. Once upon a time you could simply cast that to (NSData *) and work with it that way, but Xcode now flags it as an error:
dispatch_data_t data_t = BGRequestSidebandDL(channel);
NSData *nsdata = data_t; <<<
Incompatible pointer types initializing 'NSData *' with an expressionof type 'dispatch_data_t' (aka 'NSObject<OS_dispatch_data> *')
Nor can I do this:
NSData *nsdata = [[NSData alloc] initWithBytes:data_t length:size];
because I don't know the size of the dispatch_data_t returned to me.
