There's been a much stronger focus on calling ObjC from Swift than the other way around, but in this talk we'll cover both directions and the parts of the Swift language involved in the process.

Swift has evolved since 1.x to have a fluctuating amount of magic/implicit bridging from ObjC and Foundation types, sometimes going in the opposite direction towards very explicit type conversions. We've started seeing more of what the "steady state" looks like as Swift 3.x/4.x development matures. In the early days, Swift users would need deep compiler internal implementation details to know which NSNumber-representable type could implicitly convert. As of SE-0139 that's a lot clearer.

Every Swift developer who has migrated code bases from Swift 1.x to 2.x, or even the more tedious 2.x to 3.x knows the pain of migrating to new Swift versions. In this episode, we cover: What is a source breaking change? Almost guaranteeing that code that compiles with Swift 3.0 continues to compile with Swift 3.x and even Swift 4.x in Swift 3 mode. Why almost? Because it may be best to prevent code that never should have compiled with Swift 3.0 (i.e. compiled due to egregious bugs in the compiler) from compiling as those bugs are fixed. There are times when breaking compilation is preferable to continuing to exploit Swift bugs. "we should try to get the “rearrange all the deckchairs” changes into Swift 3 if possible, to make Swift 3 to 4 as smooth as possible": https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20160125/007737.html Community-driven breakage ;) Slava Pestov (@slava_pestov) found and fixed a 'horrific' Swift 3 compatibility bug. When they say Swift 3.1 will be compatible with Swift 3, they're serious. 😅 Dollar Sign https://github.com/apple/swift-evolution/blob/master/proposals/0144-allow-single-dollar-sign-as-valid-identifier.md Swift Weekly Issue 39, https://swiftweekly.github.io/issue-39/ Slava Pestov changed variadic closure arguments to be @escaping by default, which is technically a source breaking change, but only for invalid code. Issue 42, https://swiftweekly.github.io/issue-42/ Robert Widmann merged changes to reject standalone $ as identifiers, which were accidentally accepted as valid. Issue 43, https://swiftweekly.github.io/issue-43/ Rintaro Ishizaki has submitted a pull request to fix SR-2843. In type parsing, P1 & P2.Type (new protocol syntax) was incorrect. DougGregor fixed an unintentional source-breaking change from Swift 3 regarding implicitly-unwrapped optionals and type inference. Minor source breaking change for sugared types: https://github.com/apple/swift/commit/4ebac86895383ad15e34de3671c6f423e96cfc98 Running the entire test suite with version 3 or 4: https://github.com/apple/swift/commit/1fcd7d725d1c23a27d4ea31e34e20f182e0b8c37 Ignored Labels for single-"Any"-argument functions https://github.com/apple/swift/commit/30c4235193b64050f8110ef5598c7efb4501e0da Xcode 8.2 last release for Swift 2.3!

In this episode, we dive into the framework we love to hate to love: SourceKit. We wrap up with an overview of method dispatch in Swift. SourceKit on Linux Swift core team is fixing compiler crashers faster than they're filed! Slava Pestov being a driving force behind many of these fixes. @practicalswift is basically Swift compiler fuzzing as-a-service ;) Undoing all of @practicalswift's hard work SourceKit home page Process Isolation Key contributors to SourceKit: Brian Croom and his many SourceKit PRs to help get it linking and compiling on Linux.

In this episode we take a look at the first full year of open source Swift development and the first complete release cycle (for 3.0) that happened completely in the open. We reflect on where we've been and how we got here. We discuss the initial launch, Swift evolution, the "Great Swift 3 Migration", and more!

There are tons of podcasts out there about general Apple/iOS/macOS development but nothing specifically about only the Swift programming language. So, we decided to make a podcast about the Swift language and a commentary on the Swift Weekly Brief. This podcast is a continuation on more details about Swift Weekly and our own thoughts on Swift news.
