I received a follow up question, asking how I added the unified
NSToolbarvisible in the app screenshot. Walkthrough here: dev.to/hugh_jeremy/adding-a-unifie...Hi, thanks for this tutorial about NSTableView in SwiftUI. Would it be possible for you to upload your project that does this successfully? I keep running into errors and crashes on initializing from NSViewControllerRepresentable and makeNSViewController. I am currently getting this when returning from makeNSViewController:
-[NSNib _initWithNibNamed:bundle:options:] could not load the nibName: EntityNSTableViewController in bundle (null).
followed by a EXC_BAD_ACCESS crash when the window is brought to the front.
Hi Mark, sorry for my slow reply! I have been doing some more work with
NSTableViewin SwiftUI recently, so it's possible I could smash something together to upload... I have a few macOS apps in the pipe that I might be able to open source. I'll try to do so soon!I'd also love an example project! I'm learning to build a MacOS app and it's tough to learn aspects of NSTableView concurrently with SwiftUI concepts...
Yeah NSTableView definitely requires a totally different mindset than SwiftUI. I'd recommend building some stuff in AppKit to get used to the "old" way of doing things. It's so common to need to drop back down into AppKit, and NSViewRepresentable becomes very important. Another example is AuthenticationServices - To add a "Sign in with Apple" button you're back in AppKit land writing @objc interface implementations!
I wanted to understand how .refresh() method works? Do you need to add the functionality in the class PlayerNSTableController: NSViewController {} or is this an automatic thing?
Also maybe this is irrelevant but if i want to do the same in ios app, i can use table view from uikit. My main worry is how i can make additional functionality on the table for example if i want to highlight one of the rows in the table. How can i accomplish that in swiftui interfacing to appkit or uikit. Do you know?
Hi Hassan! I've never done any work in UIKit, so I can't speak for how similar the UIKit TableView is to the AppKit NSTableView. My impression is that generally UIKit and AppKit classes have only superficial similarities.
As for additional functionality - Honestly, I've found that NSTableView is great for simple tables, but can get fiddly if you try to skew it too far beyond Apple's vision for what constitutes a "table". The key is to use NSView as the basis for your cell views - Get comfortable with drawing custom NSViews, rather than trying to tweak something like an NSButton to suit what you're trying to do.
Overall, I would say the best option is to ditch AppKit and UIKit and work with SwiftUI. It's far easier to create fully custom tables as SwiftUI views, in my opinion. Here's some first impressions I had of SwiftUI: dev.to/hugh_jeremy/swiftui-first-i...
Thanks for the tutorial - but is it really far easier to create a fully custom table view in SwiftUI? How do you handle the column auto sizing and ability to manually resize them?
This tutorial is a hoax. Even the class
PlayerNSTableViewfound nowhere in anywhere else.Thanks for the write up.
These tips allow us with good existing code to upgrade to the modern world of swift ui.
Hello,
I work with SwiftUI 2 (and I am a beginner) and I don't know how to add the module DraftSport and I don't know what DraftSport is...
