struct MyStruct {
var count = 0
mutating func add(amount: Int) {
count += amount
}
}
var myStruct = MyStruct()
[1, 2, 3, 4].forEach(myStruct.add)
This code currently doesn’t compile because myStruct.add is a partial
application of a mutating method, which is forbidden. However, in my
understanding, this cannot cause problems inside forEach because its body is
marked @noescape. So, could we allow partial applications of mutating methods
in @noescape contexts?
