Hello @gfreezy,

The async version of GRDB read(_:) requires an @escaping closure. Your own read(value:) should require an @escaping closure as well:

static func read<T>(value: @escaping (Database) throws -> T) async throws -> T {
//                         ~~~~~~~~~

Please update your code, and report if this change removes the warning.

@escaping is not enough. After adding @Sendalbe @escape, it works.

Seems the document is outdated. There is no @Sendable in the document.
