Plus if you want to play with Swift 4 without running a toolchain or the new Xcode you can do it in your browser:
https://swift.sandbox.bluemix.net/#/repl Just change that repl to Swift 4. -- Adrian Zubarev Sent with Airmail Am 1.

I don’t have access to the Swift 4 API documentation, since i’m not running the xcode beta yet. Is there someplace I can see the actual new API’s for String, in swift 4? i googled but haven’t found it yet.

Is this perhaps only in Swift 4? If so, that’s a definite improvement!

It might be a good idea to look up possible API first before writing such ugly long lines. I mean they get the job done, but just why so complicated? :( -- Adrian Zubarev Sent with Airmail Am 1.

Python: shortID = longerDeviceID[-2:] # give me the last two characters Swift: let shortID = String(longerDeviceID.characters.dropFirst(longerDeviceID.characters.count - 2)) I can’t even read the above without my eyes glazing over. As has been pointed out, an API which demands this much verbosity is crippling for many developers, to say the least. With Swift 4, am I correct that it will be at least: let shortID = String(longerDeviceID.dropFirst(longerDeviceID.count - 2)) _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
