it easy use realm classes inheriting object . how save struct containing several fields realm in swift? e.g. struct datamodel { var id = 0 var test = "test" } i know documentation clear supported types. maybe there nice workaround or - better - realm write future plans structs. to save struct in realm, means copying data realm object . reason why realm objects classes , not structs because not inert values, auto-updating objects represent persisted data in realm. has practical benefits, such fact realm object 's data lazy loaded. you can take advantage of realm's approach responding change notifications realm instance. example if uitableview data source based off array property on realm object , long have instance of object, guaranteed after notification represents correct values. used can simplify code versus having multiple copies of values structs.

i'm working on small form app, , have "paired" radio buttons lists in common class. purpose of turn on/off corresponding list public class mytype { public radiobutton button { get; set; } public listbox list { get; set; } } i proceed create these pairs through loop inside array for (int = 0; < broj_botuna; i++) { thearray[i] = new mytype(); } i use common event handler radio buttons: private void test_checkedchanged(object sender, eventargs e) { var xx = sender radiobutton; //do stuff positioninarray = array.indexof(thearray, xx); } except last line of code "xx" should of type "mytype" , not "radiobutton" managed retrieve. so tell me how reference "radiobutton" "mytype"? or there better alternative? you can use array.findindex like: var positioninarray = array.findindex(thearray, b => b.button == xx);
