Problem with sqlcipher on iOS 12

[RWarnecke]

Hello,

i updated to SQLCipher 4.0 and change the integration from sqlcipher.xcodeproj to cocoa pod installation. The build of the app is successfully. If I run the app, I get the error message that the sqlite file is not a database. If I open the database with the SQLiteManager the key was working. What went wrong if I try to open the database ? What kind of settings I need ?

Thank you for helping
Rolf
