Sometimes the Safari App Extension i'm developing does not show up in my Safari Extensions unless i change mu bundle identifier to some unique name.
Even if I delete all other apps i've built with the same (and different) bundle ID, the extension is still does not show up.
The only solution for me is to always change the bundle ID. For example: Now it is "kopyl.tab-finder-10" If i change it to "kopyl.tab-finder-11", the extension does show up in the Safari extensions settings page again.
Is there any other way to fix it?
