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 compil...
