FAQ

Why isn't Sift on the App Store?

It turns it out that network content filters are not permitted for regular app store apps (it only works in supervised device mode). So I decided to release the source code instead -- any donations are greatly appreciated :)

How do I run this on my own device?

Change the development team to your own in both the app and extensions targets, search for occurences of "in.alexgr." in the project and replace each one with your own team identifier. Follow this open-source contributed guide for more help.

Is there XCode 10 support?

Yep -- just switch to the xcode-10 branch.
