Swift 4.0 support

[swftvsn]

Would be awesome! Is there any work done on this?

There is a swift4.0 branch.

I didn't had any issues with Swift 4 & Xcode 9 on my end. It's working great. I also don't remember needing to specify that branch... 🤔

I think the swift4.0 branch has been superseded by beta releases such as 4.0.0-beta.0:

tweet:

I've published 4.0.0-beta.0 this morning at ~ 2:00AM

tweet:

We are planning to release 4.0 mid October, we are in beta right now.

But I'm not sure it's the correct way to go: the swift4.0 branch may have the same content as the 3.6.1 release + Swift 4 compatibility, when the 4.0.0-beta.0 tag may have breaking changes towards the future version 4.0.

@kzaher: it looks like the community could enjoy some "official" communication on Swift 4.

But RxCocoa currently does not support Swift 4

[kzaher]

I've updated the README.md file with

• RxSwift 4.x / Swift 4.x can be found in rxswift4.0-swift4.0 branch.
• RxSwift 3.x / Swift 3.x can be found in master branch.

Currently CHANGELOG.md represents official communication about releases.

## [4.0.0-alpha.0](https://github.com/ReactiveX/RxSwift/releases/tag/4.0.0-alpha.0)
* Swift 4.0 compatibility
* Changes delegate proxy to use plugin architecture.

It seems like iTunes Connect does not like having "4.0.0-beta.0" as the CFBundleShortVersionString value. When trying to upload my app via fastlane pilot I get the following error: [Transporter Error Output]: ERROR ITMS-90060: "This bundle is invalid. The value for key CFBundleShortVersionString '4.0.0-beta.0' in the Info.plist file must be a period-separated list of at most three non-negative integers." Has anyone else had this problem?

@zhentan Same issue here trying to submit a new build to TestFlight using the pre-release branch

[Vkt0r]

@zhentan For the moment you can use this workaround if you're using Carthage https://github.com/AFNetworking/AFNetworking/issues/3092#issuecomment-150605547 or with Cocoapods you can use CocoaPods/CocoaPods#4421 (comment). I hope this help you for the moment

Hi,

4.0.0-rc.0 is out. We'll release this in a week unless we find some big issue.

If you see some issue with the public API or some functionality, next week is the time to report it :)

Waiting and expecting for the coming big thing, haha!
Thanks for awesome job!

Any issues release 4.0.0 @kzaher ?

[kzaher]

@AJ9UNiDAYS I'm doing some final checks and trying to figure out did I forget to fix some part. I'll publish it once I finish running tests. Hopefully today.
