I'm trying to experiment with a Catalyst version of my iPad app. I checked the checkbox, I selected the "My Mac" scheme, I ran... and then, code signing errors! In the "Advanced" WW session, it works like magic with Automatic Signing. Unfortunately, I support CarPlay and thus have to manually sign my app. Not as magical.When I checked the checkbox, the Signing & Capabilties tab added a new macOS platform entry, and a bundle identifier: maccatalyst.com.mycompany.myapp. That maccatalyst.com bundle ID isn't dispalyed in my Certifiicates, Identifiers & Profiles section of the Apple developer site. When I try to add it manually, by adding an App ID, choosing Mac and specifying the explicit bundle ID, I get the following error: An App ID with Identifier 'maccatalyst.com.mycompany.myname' is not available. Please enter a different string.How do I proceed?

I'm using Core Data automatic NSManagedObject subclass generation, with a custom Class Definition. I want to update a non-managed property when a managed property value changes. So, I'm trying to use the override accessor enhancements from iOS 10.0 (https://developer.apple.com/library/archive/releasenotes/General/WhatNewCoreData2016/ReleaseNotes.html):- (void)setDepartment:(Department *)value // invoke the dynamic implementation of setDepartment [self managedObjectOriginal_setDepartment:value]; NSLog(@"invoked %@", NSStringFromSelector(_cmd));Problem is that my custom class is in Swift, so I'm at a loss on how to do this override. I've triedmanagedObjectOriginal_setProperty(property)But it gives me a compiler error. Is there any way to use this in Swift?

In Apple's crash organizer, I'm seeing a handful of crash reports come in. It doesn't appear to be a widespread issue, but keeps happening now and again.Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Termination Description: DYLD, Library not loaded: @rpath/libswiftCoreGraphics.dylib | Referenced from: /var/containers/Bundle/Application/7208AD66-5D56-4973-88A9-8D22D7E541DB/myapp.app/myapp | Reason: no suitable image found.
