I have a simple, Swift based, macOS application, written & maintained in Xcode, that I now want to run through Apple's Developer-ID "notarisation" service for distribution. However, whenever I try to upload an archived build of the application, Xcode gets stuck at the "Uploading package to Apple Services..." step of the process.
My process is as follows:
- In Xcode "Build --> Archive"
- In Xcode's Organizer: Distribute App --> Developer ID --> Upload --> Automatic Code Signing
- The issue now occurs during upload.
I have already tried notarising a simple sample-app with no code beyond what the standard Swift macOS project template includes and that app also gets stuck at this step. (So this should eliminate issues with the Code / binary of my project itself.)
I have also attempted to use xcrun altool to upload my binary to the notarisation service using the command: xcrun altool --notarize-app --primary-bundle-id "com.me.myapp" --username "myuser@memyselfandi" --password "mypasswd" --file myfile.zip.
The result here is similar: The command gives no output and hangs.
Every time I attempt an upload to Apple Services I also notice that a process called ascp is uploading rather large amounts of data, many multiples of the size of the archive I'm attempting to upload to Apple. I'm not 100% certain of how this might be related, but the process always appears when uploading through Organizer or the xcrun altool command.
I'm using Xcode 10.2.1 and macOS Mojave 10.14.4.
