After making the LineUp class that can be iterated starting with 1 (Zero is for programmers) Customers start at ONE. Now I want the iterator to wrap around... like a team that bats around the line

// on? a slightly different note *class* LineUp { *var* lineup = [ "Bob" , "Tony" , "Iris" , "Jane" , "Nan" , "Dave" , "George" , "Ringo" , "Shannon" ] *subscript* (n: Int ) -> String { *return*

Right on Hassan. ?It's a different implementations ... https://github.com/Ahmed-Ali/Cucumberish So It is like Cucumber classic... I wonder if it is diet cuc or caffeine free?

OUCH! that black background - hurts the eyes... *var* str = "Hello, playground" // https://docs.swift.org/swift-book/LanguageGuide/Extensions.html // Extensions can add new subscripts to an

Per https://docs.swift.org/swift-book/LanguageGuide/Extensions.html <https://docs.swift.org/swift-book/LanguageGuide/Extensions.html>, "Extensions can add new functionality to a type, but they can’t

Help an old timer out... I don't know why this does NOT work... I want to redefine the subscript method... in Swift ... *var* str = "Hello, playground" //

perhaps I am parsing your statement poorly Jon. But I see the function in UserDefaults as Open - that's what the open keyword means. ?It is the "base" class that controls it's Open/Closed nature

David, I think of the "seam" metaphor as "a place where two pieces are loosely stitched together, so we can safely connect different pieces." But Michael Feathers is more precise: "A seam is a

Envoyé de mon iPhone It’s basically passing around a structure containing functions doing the IOs you need. In Haskell, you can use various mechanisms to represent side effecting functions:

What do you call Handler pattern ? do you have a dummy example ?

If you write pure code you'd probably push your state changes, IO (monads in haskell)... to the edges of your program, you also probably inject your functions as arguments. You asked about

'Seam' here refers to a concept popularised by Michael Feathers' book "Working effectively with legacy code" https://www.goodreads.com/book/show/44919.Working_Effectively_with_Legacy_Code There's

That example is very helpful - thank you. I don't know the meaning of "act as our seam"? ?Why do we want/need a seam? ?What is a seam? Clearly this caveman must get out my stick (ones) and dead

Let's say you have code that uses UserDefaults (a persistent key-value store available in Foundation for all Apple platforms). Specifically, it calls the method for setting a persistent integer.

Don’t follow you Jon. Maybe an example would help. I’m just a simple caveman. David Koontz Email: david@... (360) 259-8380 http://about.me/davidakoontz

My favorite use of Swift extensions is wrapping a seam around an existing object: - Take a type. Any type. I don't have to own it. - Define a new Protocol which is a slice of that class (ISP) - Using

I’ve been pondering for a few days about this. Asked a knowledgeable colleague and still wondering. https://docs.swift.org/swift-book/LanguageGuide/Extensions.html Swift has this awesomeness
