[swift-users] Can Swift 2.3 frameworks be used with a Swift 3.0 app?

[Ted Bradley]

So does that mean then that Swift 2.3 and Swift 3.0 can interoperate?

E.g.

iOS Target ‘Foo’, imports a custom Framework ‘Bar’

Foo is Swift 3.0
Bar is Swift 2.3

You need to wait until they are promised to work with 2.3 or 3.0. If you can get the source code, you can use migration tool and compile the framework yourself.

Ah, I wasn’t being clear :)

I meant user created frameworks. Such as you would get manually or via Carthage / Cocoapods. Could those be migrated to Swift 2.3, whilst your main target is migrated to Swift 3.0?

As a temporary stop-gap of course.

I don't know which frameworks you talking about. The Foundation framework is definitely different. But Cocoa and Cocoa Touch should be the same.

From what I’m reading in the documentation, it seems like everything needs to be either all Swift 2.3 or all Swift 3.0 – no mix and matching.

Unfortunately, the beta has been pretty unstable on my system so I’ve not managed to get enough time to test this out yet. Appreciate hearing from anyone who knows definitively or has tried this.
