安装

Note: SQLite.swift requires Swift 1.1 (available in Xcode 6.1).

To install SQLite.swift:

  1. Drag the SQLite.xcodeproj file into your own project. (Submodule, clone, or download the project first.)

  2. In your target’s Build Phases, add SQLite iOS (or SQLite Mac) to the Target Dependencies build phase.

  3. Add the appropriate SQLite.framework product to theLink Binary With Libraries build phase.

  4. Add the same SQLite.framework to a Copy Files build phase with aFrameworks destination. (Add a new build phase if need be.)
