I'm developing a companion watch app for an already existing iOS app, and everything seems to be working fine compiling it for the simulator, however when I try to archive it so I can make it available on TestFlight XCode throws the error "The stickers icon set or app icon set named "AppIcon" did not have any applicable content" even though the app icon is in the assets.
The icon works and appears fine under the Simulator but I can't seem to archive it, even after renaming it to something else.
