Disclaimer: I don’t work or speak for Apple, so this is my opinion: I can’t speak for the major dev shops, but in my small group, we’ve used Objective-C++ both for integrating C++ libraries, and as you propose for writing backends in C++. As @alxp mentions, things like exception handling across the language boundary are … Read more
Instead of overriding any of the init methods you can simply override the windowNibName property and return a hardcoded string. This allows you to call the basic vanilla init method to create the window controller. class WindowController: NSWindowController { override var windowNibName: String! { return “NameOfNib” } } let windowController = WindowController() I prefer this … Read more
Unfortunately, there is no way to bundle a framework with a command-line Utility in OS X and I suspect that the framework you’re linking to is expecting to be bundled in the app bundle’s Frameworks/ directory. If you have access to the framework source code, you can compile a static library and statically link it … Read more
initWithFormat:arguments: NSString *estr(NSString *format, …) { va_list args; va_start(args, format); NSString *s = [[[NSString alloc] initWithFormat:format arguments:args] autorelease]; va_end(args); return s; } they don’t seem to have a convenience constructor “stringWith…” version

In a technical sense, yes, it is faster, for exactly that reason. In a practical sense, no, it’s not faster. For one thing, the speed difference is tiny. We’re talking milliseconds saved over the life of the entire process. The savings might be bigger on the iPhone, but it’s still pretty much the tiniest speed … Read more
Yes you can do this, but since you’re asking, I have to ask: Are you absolutely sure that you need to? (If you say “yes”, then go back, figure out what you want to do, and see if there’s a different way to do it) However, if you really want to inject storage into a … Read more
NSRange is a plain c-struct so it can be initialized the following way: NSRange HEADER_VERSION = {0, 4}; or NSRange HEADER_VERSION = {.location = 0, .length = 4}; See Designated inits section of gcc manual for more details
