Ok I noticed "ShazamKit Known Issues SHManagedSession.State is unavailable. (109670750) SHLibrary.default.items is unavailable. (109670918) SHManagedSession doesn’t work on simulator. (109672477) Workaround: Use a physical device." at https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes I would suggest apple to put this on the documentation of ShazamKit, I spend a entire day to figure out what is going on... :)
