ios - Realm Swift use locally only, however it still tries to connect online -


i following realm swift getting started guide here , working fine. have following object:

class dog: object {   dynamic var name = ""   dynamic var age = 0 }

and in viewcontroller have

override func viewdidload() {     super.viewdidload()      print(realm.configuration.defaultconfiguration.fileurl!)      let mydog = dog()     mydog.name = "rex"     mydog.age = 1      let realm = try! realm()      try! realm.write {       realm.add(mydog)     } }

little snitch reports realm tries connect static.realm.io , api.mixpanel.com. how stop realm attempting connect various servers if want use locally?

it's intended behavior.

realm collects anonymous analytics when app run debugger attached, or when runs in simulator.

please see our doc more details.

https://realm.io/docs/swift/latest/#i-see-a-network-call-to-mixpanel-when-i-run-my-app-what-is-that

it doesn't happen in release build. prevent in debug build, set environment variable named realm_disable_analytics.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
