Swift 2

[stephencelis]

This is a work in progress with much to do. It's an ambitious update that adds support for Swift 2 features along with some project file restructuring needed to support Carthage, and API restructuring needed to decouple database connections from the query builder and support database names.

It will address #133, #30, #77.

Old code has momentarily been deleted and functionality with it. This PR will not work with your existing code at the moment. See Tests and read the Source for new behavior.

Must-haves:

• Use Swift 2 error model
• Use protocol extensions
• Feature parity
  • Re-hook up asc, desc, alias
• Re-hook up SQLCipher
• Re-hook up CocoaPods
• Finish tests (and provide as complete coverage as possible)
• Update documentation
  • Update general text and example code
  • Address FIXMEs
  • Update installation instructions and image
  • Add more specific examples around expression protocol extensions
• Update playground
• Update README (partially done)
  • Update general text and example code
  • Update installation instructions and image

Nice-to-haves:

• Decouple database connections from query builder
• Hook up Carthage
• Database name support
• Attach/detach helpers
• Pragma helpers
• Extract SQLCipher into its own SQLiteCipher.swift repository
• Section playground into chapters with more examples
• Clean up raw interface
  • Consider less subscripting and more flexibility for retrieving values
  • Use func forEach(Element -> Void) throws for lazy iteration
• Split into sub-frameworks (don't require typed builder use)
• Multi-reader/single-writer locking

Good job! 👍

Any news about when .order by .asc/.desc can be expected?

I have tried to include this WIP into a simple Project that onle wirtes a console line on a click. I cannot compile the project as it shows errors imidiately.

Should this work be know or should I keep my hands of the WIP and wait for a master version. I wanted to prepare myself for swift 2.0

@Silve2611 It should work, for the most part, but errors aren't surfaced in the most helpful way yet. Can you paste the code/errors failing in question?

[Silve2611]

I added a screenshot. But I have to admit the behaviour is Strange. Now when I build it. It fails but shows no errors. Removen SQLite from the project solves this... I have the XCode 7 Beta 3 version. I am now updating to Beta 5 and retesting it.

[Silve2611]

Since i have made the update everything is working fine. Thank you for the great work!

May be a good idea to tag a release for the current Swift 1.2 version. That way when the Swift 2.0 version comes out you can do a major version bump and those who haven't made the transition can select the Swift 1.2 version until they've updated their code.

Hi I migrated to your swift 2.0 branch. How I have to migrate following coe to your optimised API?

magazines.filter(contains(favoritMagazines, DbMagazine.COLUMN_ID)) ?

thx

[stephencelis]

@cwack-letsdev Protocol extensions have made the following possible (and preferable):

magazines.filter(favoriteMagazines.contains(DbMagazine.COLUMN_ID))

[stephencelis]

Merging! A few things to do but things should be relatively stable.
