iOS developer PSA: if you're having trouble compiling your app that uses ImagePlaygroundViewController, there's a workaround. Implement the delegate on a Swift class that's not exposed to Objective-C (by making it private, for example).
Here's what my delegate class declaration looks like:

And it wasn't that all functions were called methods. Only the ones on subclasses of NSObject and NSProxy were named method. The ones written in C, were still called functions.

any #swift 6 experts out there:
I'm not sure how to fix this error.
Speaker has to inherit from NSObject because it has to act as a delegate to AVSpeechSynthesizer.
But if it inherits from NSObject, then the compiler complains that its properties are mutable (which of course they must be).

Decided to take a detour and write some scripting for ghidra to automatically recover class hierarchies based on available RTTI information. Here's the player class(the DelegateObserver inheritance is non-virtual, btw). Next up: figuring out ghidra's analysis API so I can automate all of it.

You don't find it bizarre that if you do any serious apple dev you have to type NS over and over again?! Liek even in the NeXTSTEP sdk at some point they changed NXObject to NSObject so why not XObject?! As if Rhapsoddy had some massive backcatalog of bangers... WHWT

@mattiem Do you have a personal rule of thumb for when you wrap Apple's own, old NSObject types in unchecked sendable boxes?
I'm looking at NSItemProvider a.t.m. to get UIImages from the photo picker. Nothing's sendable. All samples include dispatch groups, and dispatching the unpacked result […]

Do I know anyone who used plain C `struct`s in their Objective-C code bases, e.g. to pass data around without attaching any behavior to it?
I realize I've always reached for NSObject subclasses to represent my immutable data types, no matter how primitive, and now I wonder if I've missed out.

nil: puts a pointer to the instance of an Objective-C Object to the value 0.
Nil: don't know. I have never encountered it in production apps. I know it exists.
NULL: Is C pointer value of 0.
NSNull: A subclass of NSObject that represents the value of nothing inside an NSArray.

This Swift 6 code crashes in _dispatch_assert_queue_fail(), even if the installTap() closure is empty. If I remove the MainActor annotation on the class, it works. Anybody else seen and/or worked around this?

However, as long as those are NSObject types, there is a quick workaround. We can use NSObject metatype to bypass the restrictions. 🙃For example, take a look at working mock of SCDisplay. **Do not do this in production code**

It’s a pretty standard “Main actor-isolated property 'property1' can not be referenced from a nonisolated context; this is an error in the Swift 6 language mode”. Nothing fancy here: Just a MainObject subclass of NSObject (like a UIView or UIViewController).

To make a Swift required init for an ObjC class, put the init in a protocol:
@protocol PSPDFDocumentCreation
- (instancetype)initWithThing:(NSThing)thing;
@end
@interface PSPDFDocument: NSObject
@end
Thanks Kostiantyn Herasimov for pointing this out.

A teammate shared this screenshot from the GitHub email notification of my review of their PR. I was talking about changing `value as Double as NSObject` to use `NSNumber(value: value)` instead.
