There were a lot of changes made in the Swift 1–3 time frame as the team learned what it was like to write Swift at scale and developed a unique language style. That’s all done now, and Swift 5 code (released 2019) should continue to be compilable with few exceptions long into the future. It’s different enough from Swift 1 that it’s basically a different language though. The biggest source-breaking change on the near-term horizon (which is still in progress) is compile-time enforcement of concurrency safety. |
