Hi @andrewlim7
For the gethostuuid() warning – that is deliberate, please see this post for additional information: Warnings for sqlcipher XCode 9 gethostuuid() is disabled
There are definitely some other integer conversion warnings within sqlite3 itself, that can be safely ignored (for the time being anyway).
Could you post the warning details from your build log, and let us know if there are any specific warnings that you have a question about?
If the warnings are from upstream sqlite3 and they bother you, you should either be able to silence them with a -w compiler flag or compile SQLCipher once and link against the .a
Cheers,
Micah
