Re: Best Xcode machine mid-2019?

Compilation is largely an i/o-bound problem. Unless the projects you work on are hideously large and would benefit from parallel processing (splitting the i/o among several processors), your current machine is quite satisfactory. Try this: using your current system, create a 4GB disk

Re: Prioritizing drawing of the important stuff

Actually, there is. This sounds a lot like the resize logic built into the framework. In Apple’s “View Programming Guide” there is a section dedicated to “Drawing During Live Window Resizing” You already have the fast and slow methods for drawing so you can use them if you pay attention to

CIImage initWithCGLayer is deprecated in 10.11

Ok. Maybe this was done for performance. Whatever. Here’s the thing: I draw into a layer, then I want to apply a CIFilter to that layer. With initWithCGLayer deprecated, I can’t for the life of me figure out how to use the existing APIs to do what I want. The sample code — FunHouse — uses the

objc [66375] class Foo is implemented in both BundleA and BundleB

Class Foo is a base class. It is subclassed in BundleA, BundleB, … BundleZ. The runtime still throws that message, regardless. There are one or two methods implemented in the base class and not in the subclasses. You can see this effect if you download, build, and run Apple’s BundleLoader

There was some discussion of this on stack overflow but one of the APIs there is deprecated: LSSharedFileListItemResolve. It’s 3rd parameter takes a pointer to a CFURLRef and that is now deprecated. Instead, use LSSharedFileListItemCopyResolveURL; basically the return value from this is what
