Hi Recently I have upgraded operating system from High Sierra to Mojave, after upgrading operating system Xcode downloaded some support tools automatically. My code compiles and builds successfully, but it fails to launch application with error "Message from debugger: unable to attach". I tried all possible solutions what all I could, but none of them helped. I just want to specifically mention this is Mac (Cocoa) application. Please help me to fix this issue.

I have a xamarin application for mac OS which I tried to notarize, notarization failed with error "The executable does not have the hardened runtime enabled." As suggested by many blogs I have manually added an Entitlements.plist file and added    <CodeSignEntitlements>Entitlements.plist</CodeSignEntitlements> in .csproj file along with     <UseHardenedRuntime>true</UseHardenedRuntime>. In Entitlements.plist file it contains only com.apple.security.cs.allow-jit (Since I do not need anything specific). I sent app for notarization for the second time, but still this error "The executable does not have the hardened runtime enabled." raised by Apple Notary Service. Anyone having any idea how to resolve this issue.
