Problem with Postgres and platform version

Hello,

I'm a new SwiftUI developer and trying to create an app for iPhone.

I needed to connect to Postgres so I've used Postgres-Kit (installed >2.0.0 version) (https://swiftpackageindex.com/vapor/postgres-kit)

I've installed the package, and there's no error displayed on Xcode until I'm trying to build :

The package product 'PostgresNIO' requires minimum platform version 13.0 for the iOS platform, but this target supports 11.0

I've changed the version of iOs Deployment Target in the project navigator but it doesn't help at all.

Have you met this exact problem with Postgres-kit / PostgresNIO ? Please help !
