Add missing imports

[p2]

Adds two imports that become apparent when not compiling the original project, but adding the files directly.

[jberkel]

the missing dependency here is NSUUID
(I wonder if it's worth making this explicit, instead of doing these catch-all imports)?

import Foundation.NSUUID

[p2]

That would be an option. In case of Foundation I wouldn't think that's necessary, it's highly likely all of Foundation are imported elsewhere anyway.

[jberkel]

Not as an optimization, more as a documentation of the dependencies of the file. But it's not commonly done in Swift/ObjC.

I appreciate @jberkel's suggestions. Any chance you can make the changes before we merge?

[iNoles]

With these changes, there is no needed for @import Foundation in SQLite.h then?

[jberkel]

I think you still need it for the FOUNDATION_EXPORT macro

[p2]

Sure, works for me, updated.

Thanks!
