Swift 4.2 branch fails to build as a dependency

QuestofIranon commented 6 years ago

What did you do?

added the 4.2 branch as a dependency for a swift 4.2/ XCode 10 project pod 'GRDB.swift', :git => 'https://github.com/groue/GRDB.swift.git', :branch => 'swift4.2'

What did you expect to happen?

The library to build with Swift 4.2 set as the version

What happened instead?

Fails to build

I have to set it to build in 4.0 everytime a podfile update is required.

Environment

Hello @QuestofIranon,

You're backcountry skiing: beta Xcode + unadvertised branch. This is not for everyone.

Unless you are willing to contribute, I recommend that you step back:

pod 'GRDB.swift', '~> 3.1'

If Xcode 10 keeps on complaining, add at the end of your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'GRDB.swift'
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.0'
      end
    end
  end
end

I'm reopening this issue until Xcode 10 is out (see https://github.com/groue/GRDB.swift/issues/383#issuecomment-404127426)

GRDB 3.3.0-beta1 is out. It supports Xcode 10 beta 6 and Swift 4.2 - but one may still face Xcode-related issues.
