Have been days I am stuck on this, really hoping someone can help. I have added Widget to my existing AppKit project (macOS), and all works fine. However when I try to archive, it keeps failing at this error: 2020-11-14 23:58:29 +0000	/var/folders/gv/cqghcvl50690hwhk3bbpf7pr0000gn/T/XcodeDistPipeline.~~~HAVL4T/Root/Applications/XXXX.app/Contents/PlugIns/Mac WidgetExtension.appex: replacing existing signature 2020-11-14 23:58:29 +0000	/var/folders/gv/cqghcvl50690hwhk3bbpf7pr0000gn/T/XcodeDistPipeline.~~~HAVL4T/Root/Applications/XXXX.app/Contents/PlugIns/Mac WidgetExtension.appex: code object is not signed at all 2020-11-14 23:58:29 +0000	/usr/bin/codesign exited with 1 Have tried: Clearing and removing all certificates Upgrading to Big Sur Removed and recreate Widget Target Manually creating provisioning profiles

Running a project from Xcode 12 seems to be very slow during launch. Even the example projects from Apple. Basically it feels as if the app is stuck on the launch screen? However, if I unplug from my Mac and just launch via tapping on the App icon, it's super fast. Anyone is having the same issue?
