[swift-users] the pain of strings

[Adrian Zubarev]

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))
