My use case involves a switch statement and trying to build a case that depends on multiple typecasts. This will really help me introduce some composable/clean/less code. The generic multiple conditions won't work as I'm using let with the casting and it cant be mutated. Also, fallthrough produces a similar error.
case let foo as SomeStruct,
let foo as SomeOtherStruct:
// do whatever
Error: Pattern variable bound to type
case let foo as SomeStruct:
fallthrough
case let foo as SomeOtherStruct:
// do whatever
'fallthrough' cannot transfer control to a case label that declares variables
Those errors both make sense. Basically, Im asking if there is any way to do a typecasting/pattern-match of let foo as SomeStruct || SomeOtherStruct
Edit: for more context, Im doing reducer composition with ReSwift
And what about this?
struct S1 {
var a : String
}
struct S2 {
var a : Int
}
let x = S1(a: "Test")
switch x {
case let y where (y is S1) || (y is S2): print("S1 or S2")
default: break
}
