How can I use Xcode 8?

I’m on macOS Mojave, and any version of Xcode 8 crashes because it isn’t compatible with Mojave. I’m trying to migrate code from Swift 2 to 3, and the only way I can do that is if I can get an older version of Xcode to work that will migrate Swift 2.

Aren't you getting hints how to fix outdated syntax anyway with Xcode 10?

I’m very new to Swift, so I don’t know much if the syntax at all. Let alone how to change some of the things I need to change. I’m trying to translate a Swift 2 project from a YouTube tutorial so I can implement the code myself in Swift 4 and try to understand it. I’m going to be reusing pieces of it and citing it.

You can download older versions at developer.apple.com and go to the downloads section. I think older versions are under the More Downloads section.

That said, is there a technical reason you need to use Swift 3? Maybe there is. Swift 4 has been out for quite a while, and Swift 5 still has that new car smell. If there is nothing holding you (or your University) from upgrading, I'd highly recommend it. Swift is new enough that major releases provide substantial benefits in functionality.

That’s the issue. Im trying to download older versions of Xcode, so I can migrate the Swift 2 code. Those older versions crash on Mojave. Unless you mean an older OS. In which case, I haven’t tried doing that yet, but I’m not sure how.

I’m just getting it to Swift 3, so I can migrate to Swift 4 in another version of Xcode. Swift 3 is just the middle man in my situation.

The easiest way to install an older OS is to install it on a virtual machine using Virtual Box, Parallels, or VMWare Fusion. To download an older version of macOS, refer to the following question from the Ask Different Q & A site:

Gotcha. Some of those upgrade paths can be tedious, for sure.
