What is the significance of specifying the toolchain here? line 27

It's there to make sure that Xcode uses the correct toolchain to run the GenerateCommonCryptoModule.swift script. It was needed prior in 0.8.x because the GenerateCommonCryptoModule.swift script was in Swift 2.3 syntax (so Xcode 8.x would fail). Since this script has been updated it should be changed to Swift 3.0. You could argue that it could be removed completely, but it is safer to leave it there in case Swift 4.0 changes anything.

OK, I see what happened here. The podspec checked in with CocoaPods has line 27 commented out (so there is an inconsistency between what's in the repo and the CocoaPods trunk). There is no reliable way of specifying Swift 3.0 explicitly (the options are com.apple.dt.toolchain.Swift_2_3 for Swift 2.3 or com.apple.dt.toolchain.XcodeDefault). Specifying default is the same as omitting it and neither approach will protect against Swift 4.0 breaking things. I'll update the podspec in the repo and it should match what's checked in with CocoaPods from now on.

Thanks for spotting this. In a few months time, when this has all faded from my memory a bit, it might have been tricky to find that error!

Glad to help! The script and .podspec are super helpful for dealing with the CommonCrypto trickery!
