How to position vertical Slider

I'm an old programmer but new to Mac and SwiftUI. I'm trying to get a vertical Slider positioned right up against the right edge of the window. Apparently this requires rotation:

Slider(value: $vx).rotationEffect(.degrees(v1))

Slider(value: $vx).rotationEffect(.degrees(v1))

But this rotation is just an effect. All measurements, bounding boxes, alignment, etc that effect its size and position behave as though it's still horizontal, which makes it incredibly unintuitive and frustrating to reason about, especially when new and unfamiliar with how positioning etc is done even for normal UI elements....

View Changing in Simulator not Preview

I've noticed that these lines of code, whenever I run them in the simulator, it would preview the changes in view. However, whenever I run them in the Xcode preview, it wouldn't change the view at all? I'm quite confused about this. ```swift import SwiftUI ...

NSScreen visibleFrame / safeAreaInsets not adding up right?

I'm trying to compare visibleFrame and frame to figure out whether the dock is currently showing on a given screen. Of course, I need to account for the menubar and any inset caused by a macbook notch as part of this. However, the number I'm getting don't quite add up right! For example, on my M2 Macbook Air: frame has a height of 956 (as expected) visibleFrame has a height of 919...

AngularGradient issue

Hello! I'm trying to replicate a 4 point gradient you see on the left, but I'm getting this weird line that doesn't let black and red connect and it looks like that colors do not start from corners, but are a bit off.

MacOS user-level custom FAT16 USB volume

There's a slightly tweaked FAT16 implementation used on some Akai samplers. I've created an emulator of one of those samplers. It supports r/w USB volumes with a custom FAT16 implementation. All of this works, but currently goes via the deprecated AuthorizationExecuteWithPrivileges for achieving raw USB volume access. Yesterday I looked into migrating to SMJobBless, but it also turns out to be deprecated. It's an incredible amount of work, and this SMJobBless example gave the same error as the "Hello job bless" I tried adding directly to my project, which is "Error Domain=CFErrorDomainLaunchd Code=4". Then I looked into using FUSE, but from what I understand, opening a raw USB volume still requires the user-level process to be elevated. Is this correct?...

Nondescript crash in my SwiftData app when trying to access a dictionary

I'm making an app for a school project in SwiftUI and SwiftData. It's a habit tracker and I have a SwiftData class for persisting basic habits. Where the problem started is that I'm trying to implement a way to track when a certain habit was completed. I deleted my existing instances of the class and added a dictionary under self.isCompleted as [Date:Bool] (so 3rd of August = true etc.)...

SwiftData and Canvas Previews confusion

Has anyone gotten the SwiftData, SwiftUI, and Live Canvas Preview features to work in conjunction with each other? I can get the previews working if I don't use SwiftData, but when I try to have a view that uses SwiftData, Xcode seems to error out at times for non-obvious reasons, and I'm not sure if there's a recommended way to fix those problems. I've been trying this approach with limited success: https://stackoverflow.com/questions/76543560/how-to-preload-data-into-swiftdata-model as sometimes my data model classes (which have @Relationships to other models) end up causing Xcode errors....
