The first method is tooooooooo verbose since I have to create an empty object. The second method is unsafe when obj is nil. What I wan is simple. print("object: \(obj)" should just print out either object: Lang:en name:(none) or object: or object: nil when the object is nil.

It's already listed under the section with "Embed & Sign"

The special ! char denotes "Implicitly Unwrapped Optionals" which suits many scenarios.

That's for iPhone. My app runs on macOS.

EDIT: Tag is simple, but it's readonly. I am just curious to know how to find the row of cell in the table?

I am not on iOS project, NSTableView does not have indexPath(for:) method, so I will stick to the tag thing.

It's my fault. I did not read the article thoroughly. The article has example code which I did not observe.

Yeah, that's fantastic! I seldom use the symbol navigator and when I tried to use it it demonstrated problems.

This is just the situation where people feel helpless. We can't do anything to it. It's just by design. Another pain for me in Swift is that it does not explicitly support namespace. Apple is genius but sometimes they just fell asleep when making decisions.

Thanks for your effort and replies. Sorry I cannot make your reply as answer because my question does not have an answer.

Actually I think it's waste of both performance and space. I am aware that when I get a 'copy' of an array in Swift as long as I do not modify it, I actually get a special reference of the array. But when I modify it, the copy-on-write mechanism kicks in and I now get a copy. Later on, I have to replace the original array with the modified array. That's totally against my experience on other languages and systems. But, I know I cannot change anything.

Well yes, I think that is the reason. I did some hacking and I have been running Xcode 14.3.1 on macOS 12.7 for half a year.

My need is simple - search in some directories for certain types of files and process the result list.

It seems that there is no builtin support for this purpose. I will write my own logics, anyway it's not difficult at all.

I don't want to define it in IB. I want to dynamically add rows and define width and height.
