last night I was reading about the Kotlin and Swift language and wondered what corresponds to a Xojo Module in Kotlin/Swift?
Interfaces and classes seem to work analogously. Am I right about this? And how about the other structures?
Xojo Swift Kotlin
———— ————— ——————
Class class class
Interface protocol interface
Module single Swift files ?
Sub func fun
Function func fun
Structure struct ?
Delegate delegate ?
If something like Modules are possible in both language, are the also able to create nested modules? If yes, how?
Swift doesn’t have a direct concept of “Module”… what I do is group like “methods” [func] in their own .SWIFT file
A Swift Structure is struct
and where applicable Delegate is delegate, although if you are creating your own classes, you can name it whatever you want
Also don’t be fooled by the simplictiy of Xojo in relation to struct and enum, those in Swift are 1000x more powerful
Swift also allows nesting… you obviously can have func within a class, you can also nest “private” func within other func
func outter() {
func inner() -> Int {
return 3
}
let x = inner()
}
Thanks David. So the concept of nested Modules with various scopes doesn’t exist in Swift. Does that mean, all single Swift files will have public scope? How about shared properties/methods?
They have what ever scope you apply…
If you use the “xxx.swift” file as your “module”… then you can specify various classes and functions within that file as “fileprivate” … a level of scope that doesn’t exist in Xojo… Anything marked “fileprivate” is only available to other code in that same file.
