Same problem

+1 for the deprecation warnings

@jefflks, @sergeifabian, @erolando and @Rickth64 — add this to your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

That helps to silence the iOS 8.0 warning. Not the deprecation warnings. In fact, they only arise when the deployment target becomes 12.0, which is exactly what happens when I delete this key from the Pods (because it then inherits it from my project which is set to 12.0).

If you include this version into you own podspec it's not going to work, because pod lib lint will fail. The deployment target needs to be increased as well.

#515

Ignore warnings for the KeychainAccess pod like so

pod 'KeychainAccess', :inhibit_warnings => true

Then pod install.

What if using SPM ??

@kishikawakatsumi I think that the right way to resolve this issue is to remove the deprecated accessibility levels. These accessibility levels have been declared by apple as deprecated for security reasons so there is no reason to exist and be maintained in the code. May I open a Pull Request with the solution?

Documentation
kSecAttrAccessibleAlways -> link
kSecAttrAccessibleAlwaysThisDeviceOnly -> link

Do we know when these deprecated levels are going to be removed by Apple? We're coming up on new releases of iOS and macOS soon, which I worry may completely break KeychainAccess.
