Even though we just got 26.2 Beta, looks like Apple is already publishing some new instance methods coming up with iOS 26.4+Beta, iPadOS 26.4+Beta, Mac Catalyst 26.4+Beta, macOS 26.4+Beta, tvOS 26.4+Beta, visionOS 26.4+Beta and watchOS 26.4+Beta.

It’s a new overload of .task that adds:

name: — a human-readable label that shows up in debugging/profiling so you can tell tasks apart.

executorPreference: — an advanced hook to request a particular executor for the task hierarchy (for folks using custom executors).

Still supports priority: and id: (the id causes the task to restart when the value changes).

Debuggability: name makes async work much easier to trace in instruments/logs.

Control (advanced): executorPreference is there if you need to steer where non-isolated async work runs.

Familiar lifecycle: Same start/cancel behavior as the existing .task.

Like other .task variants, it starts just before the view appears and is automatically cancelled when the view disappears.

I have a command line app that I what to port to Linux from macOS. It has a few features that use AppKit (NSImage for example) that are not supported on Linux.

Is there a way to custom compile to avoid those features. on Linux but still have them on macOS? As its only a small part of the application, I'd like not to have to have two separate code bases

For example is there any in-source means to only import AppKit and use NSImage on build on macOS, perhaps with if #available(...)

However, it seems I can't do this at the top-level

import Foundationif #available(macOS 10.0, *) {    import AppKit}

Then I was then hoping to use if in functions, but it not working how I wanted for example...

        if #available(macOS 10.0, *) {            // I wanted this to run only for macOS, but...            print("This gets printed on Linux and macOS")        } else {            print("This never prints")        }

Seems #available(...) is always true on Linux, or I'm doing this wrong

Or, maybe there is a way to leverage the SPM to build with different source files depending on the platform? I'm quite new to SPM and I think I'm struggling to find the right set of words to google for platform dependent building
