This isn't an issue with ObjC support in general, but rather shows that ObjC string constants are odd beasts. You can work around this pretty easily by making dynamic strings:
(lldb) expr --top-level -- NSString *string = [NSString stringWithUTF8String: "This is a string"]; (lldb) expr string (__NSCFString *) $0 = 0x00000001002001b0 @"This is a string" Please file a bug about the problem with ObjC constant strings.
