swift - Cannot get first(where:​) to work with [NSDictionary] -


i have array of nsdictionary's , want dictionary out of array specific key "id". tried following error:

cannot call value of non-function type 'nsdictionary?'

consider following example of trying do:

let dictionaries: [nsdictionary] = [nsdictionary(dictionary: ["id": "123", "name": "the name"]),                                     nsdictionary(dictionary: ["id": "456", "name": "the other name"])] if let dictionary = dictionaries.first(where: { $0.objectforkey("id") == "123" }) {     print(event.objectforkey("name") ?? "") }

the problem result of objectforkey (object(for:) in swift 3). nsdictionary, has no types, result any?. cannot compare any? string. cast string needed:

if let dictionary = dictionaries.first(where: { $0["id"] as? string == "123" }) {    print(dictionary["name"] ?? "") }

the error message not make sense though.

you can avoid problem if use swift dictionary, or better, parse dictionaries structs/classes , work classes. never use dictionaries represent objects in app outside of decoding/encoding.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
