I'm trying to get my macOS app running natively on the Apple Silicon DTK and it's going fine so far. Unfortunately it makes use of a third party library which isn't (and probably won't ever be) available in form of a Universal Binary. This should be no problem, though, because I've been using that library via XPC before and the documentation clearly states that mixed architectures are supported as long as they are out-of-process. So I went ahead and configured Xcode's build settings as follows for the x86-only XPC target: ARCHS: x86_64 VALID_ARCHS: x86_64 The main app and also the XPC compile fine. But when running the app it fails to launch the XPC with the following error in the console: oah error: /var/db/oah/e089a6709d38c1a085254c76a7cb592fcceddb3f234a4aa318bb4ec25fe40d27/a37f39d2b061393d7731233ae89d90cd87c97f4edeeb46a78ad791/ c43ac96d2b/my.xpcBundleID.aot: unable to mmap __TEXT: 1 Does anyone know what's going on here?

How do I create a multi-colored custom symbol? I know how to export, modify and re-import regular SF Symbols, but surely there must be a way to make a custom multi-colored one, too. Does anybody know?
