error: cannot convert value of type 'T.IndexDistance' to expected argument type 'Int' about surge HOT 8 CLOSED

My cocoa pods version is 1.5.3. So it is fairly recent. Btw, I tried to install Surge on another machine that uses Xcode 9.4.1 and Swift version 4.1.2, and Surge was installed without any error. I think DistanceIndex was taken out at 4.1 instead of 4.0 (see here). So maybe the .swift-version file should be updated to 4.1?

Ah, good catch. That's probably it. Will update to 4.1.

IIRC, Swift 4 changed the semantics for collection index distances such that they're now Int, whereas before they were a generic IndexDistance type. Can you please confirm that your project is compiling with Swift 4 and not Swift 3?

@alejandro-isaza I just noticed that Surge doesn't specify any Swift language requirements in the README (though we do have a .swift-version file). It'd be great to make the Swift (and Xcode) version requirements explicit.

I see. Thanks for your prompt response.

If I type swift --version, it returns

Apple Swift version 4.0.3 (swiftlang-900.0.74.1 clang-900.0.39.2)
Target: x86_64-apple-macosx10.9

But how should I make sure Carthage is using this version? In Xcode Build Settings, I can change Swift Language Version between 3.2 and 4.0. But it doesn't affect the swift version shown in the command line. Sorry I'm new in this. Thanks for your help.

Btw, I also tried CocoaPod to install Surge. In Xcode, I had Build settings > Swift Language Version > Swift 4.0. It shows the same error message.

I have never seen this. Make sure you have the latest version of CocoaPods. Alternatively if you can share your project I can have a look.

Pushed 2.2.0 to CocoaPods

👏 Thanks, @alejandro-isaza!
