Integrate in Xcode Version 9.0 beta 3. Issue: Declarations from extensions cannot be overridden yet

Please see screenshot.

I am getting the same problem with XCode 9.0 Beta 5. Any solution yet?

[abhijithExperion]

@ravi8x How are you showing menu on the view controllers which is not pushed but instead presented? Any solution?

[ravi8x]

@abhijithExperion No Abhijith. I have written my own Slider Menu class with very minimal functionalities.

this is a very easily reproducible "bug"; just check out the current branch and import the library to a project using Swift 4 (e.g. XCode 4 Beta 1-4). Probably it is an easy fix...

@andylamp I am using with pods pod 'SlideMenuControllerSwift' What changes required when using pod with swift 4, XCode - Version 9.0 beta 3 (9M174d). Thanks

@KrishnendraPrakash the solution, albeit with warnings, for now it seems to be that you have to put the following:

    @objc public func openLeft() {
      slideMenuController()?.openLeft()
    }
  
  
    @objc public func openRight() {
        slideMenuController()?.openRight()    }
  
  
    @objc public func closeLeft() {
        slideMenuController()?.closeLeft()
    }
  
  
    @objc public func closeRight() {
        slideMenuController()?.closeRight()
    }

Specifically, these are located in lines 1055-1075 in SlideMenuController.swift -- they should work but XCode will complain about deprecated functionality... but it's a temporary solution for the time being.

Hope this helps...

Anybody know if there will be a release for Swift4?

We need the solution via pods installation

[akshayiosdeveloper]

Not compatible with swift4

[andylamp]

@akshayiosdeveloper as I said, you can alter the source file as indicated in my previous answer and it will run just fine...

[KeimyPlaza]

@akshayiosdeveloper you can use too branch of Swift 4 if you use as pod.

@andylamp I hope you MR is comming soon.

[arun-perk]

@andylamp You are right but if we use Pod file, It will auto update when we update our other pod files, right ?

[andylamp]

@arun-perk you can use the pods git branch tool in order to have a specific version, this can be done easily like so:

platform :ios, '11.0'

target 'YourAppName' do
  use_frameworks!
  # more pods...
    pod 'SlideMenuControllerSwift', :git => 'https://github.com/dekatotoro/SlideMenuControllerSwift.git', :branch => 'swift4''
  # even more pods...
end

Hope this helps.

Update your pod https://guides.cocoapods.org/using/getting-started.html " sudo gem update cocoapods " in terminal

Note : it work for me 👍
