Usage & Sample

var cancellables: Set<AnyCancellable> = []
struct MyStruct {
    let str:String
    let int:Int
}
@CanSubscribe var myString:String? = "a"
@CanSubscribe var myInt:Int = 1
@CanSubscribe var myStruct:MyStruct? = .init(str:"q", int:9)

print("str : \(myString!)")
print("int : \(myInt)")
print("struct : \(myStruct!)")

myString = "z"
myInt = 999
myStruct = .init(str:"x", int:888)

print("str : \(myString!)")
print("int : \(myInt)")
print("struct : \(myStruct!)")

$myString.publisher.sink {print("str-sink : \($0!)")}.store(in: &cancellables)
$myInt.publisher.sink {print("int-sink : \($0)")}.store(in: &cancellables)
$myStruct.publisher.sink {print("struct-sink : \($0!)")}.store(in: &cancellables)

myString = "b"
myInt = 2
myStruct = .init(str:"w", int:8)
myString = "c"
myInt = 3
myStruct = .init(str:"e", int:7)

print("str : \(myString!)")
print("int : \(myInt)")
print("struct : \(myStruct!)")
