Nativescript IOS Build failed with Swift 3 @objc inference in Swift 4 mode is deprecated

[lostation]

Hi Osei,

I’m suddenly getting an error trying to build my Nativescript iOS app version… until there it was building correctly and running both on iOS and android... I've updated NS to 6.5.0.

I’ve already retry removing node_modules, npm install and so on… but I’m still stucked at this point.

The described building issue seems to be linked to the Toast-Swift library used from your Nativescript-toasty library.

.../platforms/ios/Pods/Toast-Swift/Toast/Toast.swift:307:15: error: method 'makeToastActivity' with Objective-C selector 'makeToastActivity:' conflicts with previous declaration with the same Objective-C selector

** BUILD FAILED **

Do you have any idea how to solve this... ?

Thanks for any help

I've just replaced your external Toast-Swift dependency from the Podfile with

pod 'Toast-Swift', :git => 'https://github.com/scalessec/Toast-Swift.git'

And it seems to make the workaround for now... Maybe just an update from your own fork of this Toast-Swift library.

Can you check if revert to the original library has no side effect or missing NS feature ?

Thanks.
Lo.

No it doesn't work... the toast doesn't appear anymore...grrr
It just remove the old deprecated issue...so the build works...but not the feature ; - (

Can you try to update your own Toast-Swift repo ?

thanks
Lo.

This issue occurred after I installed a new lib into my project -> Nativescript-markdown-view.

this lib was changing the Xcode build configuration for all the pods.

Link to the markdown lib

So I've set Xcode build param to :

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['SWIFT_SWIFT3_OBJC_INFERENCE'] = 'Default' end end end

@lostation, try to force swift version to 5 accordingly to this tutorial.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'Toast-Swift'
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '5.0'
      end
    end
  end
end
