Rxswift: Swift 4.2 macOS kCAMediaTimingFunctionEaseInEaseOut has been renamed

[asomethings]

macOS app won't build because of "kCAMediaTimingFunctionEaseInEaseOut" has been renamed to "CAMediaTimingFunctionName.easeInEaseOut" error.

Expected outcome:
The build should succeed and the app should launch.

What actually happens:
macOS app won't build because of below error

kCAMediaTimingFunctionEaseInEaseOut" has been renamed to "CAMediaTimingFunctionName.easeInEaseOut

Self contained code example that reproduces the issue:

  No code since it's a problem while building it.

**RxSwift/RxCocoa/RxBlocking/RxTest version/commit**

  RxSwift / RxCocoa - 4.2 (Branch: develop #1707 - 64394bcc936e876621561a2f56a39c1ec7f75b2d)

**Platform/Environment**

  - [O] macOS
  - [ ] tvOS
  - [ ] watchOS
  - [ ] playgrounds

**How easy is to reproduce? (chances of successful reproduce after running the self contained code)**

  - [O ] easy, 100% repro
  - [ ] sometimes, 10%-100%
  - [ ] hard, 2% - 10%
  - [ ] extremely hard, %0 - 2%

**Xcode version**:

Xcode - 10.0 (Beta 4)
```

Installation method:

• [x] CocoaPods
• [ ] Carthage
• [ ] Git submodules

I have multiple versions of Xcode installed:
(so we can know if this is a potential cause of your issue)

• [ ] yes (which ones)
• [x] no

Level of RxSwift knowledge:
(this is so we can understand your level of knowledge
and formulate the response in an appropriate manner)

• [x] just starting
• [ ] I have a small code base
• [ ] I have a significant code base

The code seems fine on our side, and also - I can't reproduce this. Would you want to provide a reproducible example?

[asomethings]

Below is the part where the error occurs

https://github.com/ReactiveX/RxSwift/blob/7242124ac809533a9f4aaee0880af54d587bf903/RxCocoa/Deprecated.swift#L398-L399

The error comes out in above saying

'kCAMediaTimingFunctionEaseInEaseOut' has been renamed to 'CAMediaTimingFunctionName.easeInEaseOut'
Replace 'kCAMediaTimingFunctionEaseInEaseOut' with 'CAMediaTimingFunctionName.easeInEaseOut'

And if I fix the code like below it works fine like a charm.

transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
transition.type = CATransitionType(rawValue: transitionType)

Since I'm using develop branch with Swift 4.2 / Xcode 10 Beta 5 it may not occur to older XCode's or lower swift versions.

So about reproducing, I really didn't actually insert any RxSwift codes. I just created a new project and imported RxSwift.

@rhals000327 how are you importing the framework? I had this same issue when using cocoapods, so after pod install I manually changed my swift version to '4.0' in the build settings of RxSwift and RxCocoa in the Pods.xcodeproj file

[asomethings]

@bitwit I've installed it using pod install. It should work fine with swift 4.0. But I need it with 4.2 as for it I used RxSwift 4.2 Version. I want to point out that it should be fixed with RxSwift 4.2/RxCocoa 4.2 since it should target Swift 4.2 Version.

[rhysforyou]

Yep, this issue is preventing me from pushing updates to a CocoaPod that depends on RxSwift, as there's no way to change a dependency's build settings from a Podspec,

[rhysforyou]

This should be resolved in #1741

[freak4pc]

@rhysforyou As I commented in your PR - This issue was already resolved in the 4.3.0 release. Can you describe what's the issue you're having?

[jegnux]

@freak4pc I had the same issue while working on the release of RxGesture.

I have RxCocoa 4.3.0 with Swift 4.2 and have this same chunk failing:

[rhysforyou]

Yep, still seeing the issue with my RxActions framework, the error I get is this:

@rhals000327, until pod will be updated you can use:
pod 'RxCocoa', git: 'https://github.com/ReactiveX/RxSwift', branch: 'master'

[kzaher]

I've updated master with additional fixes and added pod lint tests with two versions of Swift. Please check out these changes, if they work for you, I'll publish this tomorrow.

[jegnux]

@kzaher it works great for RxGesture 👍

[kzaher]

I've published a new release 4.3.1. If it doesn't work now, feel free to reopen the issue and provide me with the exact cocoapod command that I can run in this repo and that demonstrate the issue.

I've also added additional pod tests to travis. https://github.com/ReactiveX/RxSwift/blob/master/.travis.yml#L36
