c# - Should I re-use a Struct? -

i know structs value types , live on stack, unless declared field in reference type, , contain values in memory @ location. i'm wondering whether or not efficient or worthwhile re-use declared struct in iterated loop rather creating new 1 each time. how costly stack instantiate variables, if @ all? also, related question, if instantiate struct inside method call create local copy of struct or create first parameter of method when executes? about declarations: // worth doing... mystruct ms = new mystruct(0); (int = 0; i< 10000; i++) { ms.num = i; // ms } // ...over this: (int = 0; i< 10000; i++) { mystruct ms = new mystruct(i); // ms } public struct mystruct { public int num; public mystruct(int mynum) { num = mynum; } } and instantiation: for (int = 0; i< 10000; i++) { mymethod(new mystruct(i)); // mystruct live in scope? }

Swift Property Encapsulation -

i'm wondering "standard" way of declaring property in swift is. in particular, seems of apple's swift example code doesn't encapsulate properties (you can freely , set property without having go through getter , setter methods). (i'm used java have trouble believing that's how apple expects developers write code.) right now, have: private var x: int private var xlistener: xlistener? public func getx() -> int { return x } public func setx(newvalue: int) { x = newvalue if (let listener = xlistener) { listener.onxset(x) } } but feel there must simpler way this. saw mention of computed properties seems don't store value, use them you'd have do: private storedx: int public var x: int { { return storedx } set { storedx = newvalue } didset { if (let listener = xlistener) { listener.onxset(storedx) } } } i have trouble believing either of these meth...
