Swift 2 protocols renamed about box

[clarisli]

I am getting the following errors.

Box.swift:6:37: error: 'Printable' has been renamed to 'CustomStringConvertible'
Box.swift:31:10: error: 'toString' has been renamed to 'String'
Box/MutableBox.swift:8:51: error: 'Printable' has been renamed to 'CustomStringConvertible'
MutableBox.swift:25:10: error: 'toString' has been renamed to 'String'

The errors were caused by ReactiveCocoa that I use.
In ReactiveCocoa's Cartfile, it calls github "antitypical/Result" ~> 0.4.4. I added github "antitypical/Results" "0.4" to my own Cartfile to solve this problem.

Yeah, this project hasn't been fully updated to support Swift 2.0 because with the advent of indirect, it's not that useful. There is an issue (#26) about needing to update the documentation to reflect this. I don't actually think that there are any Swift 2 compatible libraries using Box as a dependency at this point, either.

Would either of you be interested in opening a PR to flesh out the Swift 2.0 support?

[philipengberg]

The newest version of ReactiveCocoa as a cocoapod has a dependency to Box, which is what caused this error for me.

Verstion 3.0.0 of ReactiveCocoa only uses Swift 1.2, but I guess that since my base SDK is iOS 9, Xcode tries to compile it as Swift 2?

[gfontenot]

That's because you're using Xcode 7. You'd need to use the swift2 branch of RAC (or the 4.0 prerelease) to get Swift 2.0 support.

[philipengberg]

Yeah, but that's only in alpha. Don't feel comfortable using that in large scale production app 😉 It just seems weird that you are forced to use Swift 2 in Xcode 7. It basically makes ReactiveCocoa 3.0 useless.

[gfontenot]

It just seems weird that you are forced to use Swift 2 in Xcode 7

I agree. Unfortunately that's the world we live in.

[jrmsklar]

I'm seeing that same issue with ReactiveCocoa 3.0.

[neilpa]

@jrmsklar RAC 3 targets Swift 1.2 so this shouldn't be a problem. Unless you're trying to build RAC 3 w/ Xcode 7/Swift 2 which isn't going to work.

[philipengberg]

Which is exactly why I (and everybody else) is doing.

[neilpa]

What I'm saying is that RAC 3 won't ever build with Xcode 7 because Swift 2 has lots of breaking changes. You have to use the recently tagged RAC 4 alpha if you want to use Swift 2/Xcode 7.

[philipengberg]

Yes, I am completely aware of that by now, but that does not change the fact that RAC 3 is unusable to anyone who has to support iOS 9 actively.

[neilpa]

Supporting iOS 9 devices doesn't require building with the latest tools and SDKs. Apps built against the iOS 8 SDK with Xcode 6.4 run just fine on iOS 9. If you want to be on the latest tooling you have to expect some libraries will lag behind.

[neilpa]

Besides, there is a version of RAC for Xcode 7. It's just not baked for long enough yet which is why it's still labelled as an alpha build.

[philipengberg]

Again, I know. But as I said, if you actively have to support iOS 9 specific features all you can do is use RAC 2.5 and hope that Apple will not make as many syntactic breaking changes to the next version of Swift, so that third party libraries don't have to play as much catch up. Otherwise people will be stuck with old Obj-C libraries for the sake of syntactic sugar and language features.

Leaving aside the question of what one might want this for, I’d be more than happy to accept a PR updating Box to Swift 2.0.

@robrix As far as I understand this issue, commits f152f11 and e633c97 should already fix this problem. Those commits were checked in after the latest Box release (1.2.2) tag, though, so they are effectively ignored by Carthage. A new release/tag should make everybody happy.

Edit: Everybody using Xcode 7 and Swift 2, I mean. 😜

[jrmsklar]

@neilpa, I'm trying to build for iOS 9 using Xcode 7, which as @philipengberg pointed out is not supported by the latest version of RAC.

[robrix]

@bavarious 👍 thanks.

[jlhonora]

+1 for a new release tag!

[robrix]

Tagged 2.0. I believe this should resolve the difficulties, so I’m going to close this out now.
