While installing pod file getting error "DocumentReadingOptionKey is unavailable in Swift"

Hi there, this seems to be the same issue as: #63

I'm having the same problem

Hi there 👋 Can you please provide a bit more information. E.g. what version of Swift? what version of Xcode? Can you reproduce this in a minimal project (i.e. create a new project and only install the Down pod)

I'm afraid I can't do much unless you give more hints or help pinpoint it.

[iwasrobbed]

Just an fyi: I tried reproducing this in a clean project on Xcode 9 and Xcode 9.2 using Swift 4 and cannot repro.

platform :ios, '10.0'

# ignore all warnings from all pods
inhibit_all_warnings!

# use frameworks for Swift
use_frameworks!

project 'Down-Integration'

target 'Down-Integration' do
  pod 'Down'
end

For me this happened during pod install, but while trying to build the app.

It ended up being because my project was still swift 3.2, while Down is expecting Swift 4?

I think you can get around by downgrading down (0.3.3), migrating to swift 4, then updating to down 0.5.0 again.

@krummler Yes, Down is written in Swift 4 but should be capable of being used in Swift 3 projects as long as the Swift versions are set correctly in the build settings and Podfile. What version of Xcode are you using?

Examples here and here

After changed swift Version 3.2 to 4 it started working Thanks

I got this now, with XCode 9.4.1, Swift 4.1
I'd bumped project target up to iOS9 for this library but podfile was still on 8.
setting podfile to 9 fixed it.
