Looks like pod install is failing. Unable to find a specification for sapcai (~> 4.0.0)

When I run this on master I get this error. $ pod lib lint sapcai.podspec

-> sapcai (4.0.0) - WARN | [iOS] swift: The validator used Swift 3.2 by default because no Swift version was specified. To specify a Swift version during validation, add the swift_version attribute in your podspec. Note that usage of the --swift-version parameter or a .swift-version file is now deprecated. - ERROR | [iOS] unknown: Encountered an unknown error (Could not find a ios simulator (valid values: com.apple.coresimulator.simruntime.ios-10-3, com.apple.coresimulator.simruntime.ios-11-2, com.apple.coresimulator.simruntime.ios-11-3, com.apple.coresimulator.simruntime.ios-12-2, com.apple.coresimulator.simruntime.ios-9-3, com.apple.coresimulator.simruntime.tvos-12-2, com.apple.coresimulator.simruntime.watchos-5-2).
