Safari Extension app is not shown in Safari preferences Extensions tab

Question

I have followed all the instruction mentioned at Creating Your First Safari Extension App. After running FirstSafariExtensionApp target, I have opened Safari preferences Extensions tab but I couldn't find My Extension in the left pane. I have Apple Developer membership and installed Mac Developer and Safari Extension Developer certificates in the KeyChain.

How to get my first safari extension app working?

Answer 1

I had the same problem, the Extension didn't show when running the app even though I made sure to allow unsigned extensions.

I could run the extension target by choosing Safari as app to run but that's not what I wanted.

It was only after I hit Product > Clean Build Folder that the extension would show up when running the app.

Answer 2

Did you enable the Develop menu in Safari and turn on the “Allow Unsigned Extensions” option?

That did not work for me, so I tried running the scheme for the extension rather than the scheme for the app. I first edited this scheme to set the executable to the containing app.

When I ran this, the extension showed up in the Safari preferences, but only while the app was running.
