[swift-users] the pain of strings

[Adrian Zubarev]

The best docs you can get without Xcode I know about is this one here: 

https://developer.apple.com/documentation/swift/string

In Swift 4 a String will yet again become a collection type.

I only know a little bit of what I’ve read online in blog posts and such.  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.

Well you’ve mentioned Swift 4 in your original post, therefore I provided a solution using Swift 4. It’s returning a view called `Substring`.

I’m sorry, but I don’t see suffix() as a member function in any documentation, nor does it complete in Xcode.
Is this perhaps only in Swift 4?

If so, that’s a definite improvement!

This looks way better than the subscript in Python and 1000 times better than your example. 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? :(

let longString = "1234567890"
print(longString.suffix(2)) // prints "90"

I know, I’ve read tons about about this. I sympathize. Unicode, it’s all very complex.

But.

BUT.

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))
