IS_ANALYTICS_ENABLED refers to Google Analytics for Apps, not Firebase Analytics.  I can see how that is confusing, but it is unrelated to Firebase Analytics.  To read more about the mechanism by which you can disable Firebase Analytics, refer to [this page][1].

I&#39;ve got an SVG file and I want to make an SvgIcon component out of it, how should I do that?

In the [documentation][1], all the examples use either predefined Material Icons or a strange notation of `&lt;path d=&quot;M10 20v-6h4v6h5v-8h3L12 3 2 12h3v8z&quot; /&gt;` which I have no idea what it is!

I am trying to use Xcode 8 to build a app with Facebook login using Swift 3. When I switch back iOS Simulator 9.3, it works. In iOS 10, I receive this error:

and

    Optional(Error Domain=com.facebook.sdk.login Code=308 &quot;(null)&quot;)

Anyone have solution for this?

### Note 1 :

After debugging, this problem is FBSDK cant update `expect_challange`. Function `SecItemUpdate` inside `security.framework` not work. This is a problem of IOS 10

In Xcode 8 beta and Swift 3, when you have a method that takes a closure as a parameter, for example:

    func foo(bar: (String) -&gt; Void) {
        bar(&quot;Hello, world&quot;)
    }

How do you document the parameters the closure takes? For example, if I wrote this:

    /// Calls bar with &quot;Hello, world&quot;
    /// - parameter bar: A closure to call
    func foo(bar: (String) -&gt; Void) {
        bar(&quot;Hello, world&quot;)
    }

In `Objective-C` it was sometimes useful to use static string constants to define alternate API keys (for example to differentiate between RELEASE and DEBUG keys for analytics packages, like MixPanel, Flurry or Crashlytics):

    #if DEBUG
    static NSString *const API_KEY = @&quot;KEY_A&quot;;
    #else
    static NSString *const API_KEY = @&quot;KEY_B&quot;;
    #endif

and then...

    [Analytics startSession:API_KEY];


How does this translate to Swift, since the Swift compiler no longer uses a preprocessor?

I have been only recently working with Xcode 8 beta 4 but it has been working fine up until now. The list of simulators is not showing for any of my projects. I already tried Creating a new Scheme and it did not work. How do I fix this?

Sometimes, it seems I can&#39;t comment my code with the usual shortcut (`command` + `/`) under Xcode 8 Beta 4. The option is disabled in the menu (screenshot below).

Do you have any idea why?
Am I the only one having this issue?

EDIT: It seems to work again after restarting Xcode... Still looking from where it comes. It&#39;s a bit annoying...

EDIT2: It still occurs on Xcode 8.1. Maybe because I have 2 versions of Xcode installed (normal and beta)? Can&#39;t fix it anymore with a simple restart!

EDIT3: the proposed `xpccachectl` command to fix it doesn&#39;t exist on MacOS High Sierra.

User does not have permission to access this object . Firebase storage android

I want to know what will happen to the users of my app that I used anonymous sign in method for them.


The Firebase documentation is really BAD and didn&#39;t explain everything and expect developer to find out himself. 
I found in its old version documentation that anonymous session will expires based on the expiration time has been set in Login &amp; Auth tab, but even there didn&#39;t mention this means just the session ends or it means that user id will remove also from my app users list or what EXACTLY happened?

I found [this answer][1] but it really is not acceptable. The number of anonymous users will grow very very fast if you do a web app and make every thing hard.
I even cannot see the number of my app users in my dashboard!!!!!
So, what should i do? should i develop a dashboard for my data myself or Firebase team should do it? At least for managing users i should have more power than just searching user with their email and when you use custom login you cannot do this also.

What happens to Firebase anonymous users?

Is there an easy way to delete all registered users from firebase console?
For example, I created a hundred users from my development environment, and now I want to delete all of them.

Delete all users from firebase auth console

As the title says, I can&#39;t get the differences between `update` and `set`. Also the docs can&#39;t help me, as the update example works exactly the same if I use set instead.

The `update` example from the docs:

    function writeNewPost(uid, username, title, body) {

        var postData = {
            author: username,
            uid: uid,
            body: body,
            title: title,
            starCount: 0
        };

        var newPostKey = firebase.database().ref().child(&#39;posts&#39;).push().key;

        var updates = {};
        updates[&#39;/posts/&#39; + newPostKey] = postData;
        updates[&#39;/user-posts/&#39; + uid + &#39;/&#39; + newPostKey] = postData;

        return firebase.database().ref().update(updates);
    }

The same example using `set`

    function writeNewPost(uid, username, title, body) {

        var postData = {
            author: username,
            uid: uid,
            body: body,
            title: title,
            starCount: 0
        };

        var newPostKey = firebase.database().ref().child(&#39;posts&#39;).push().key;

        firebase.database().ref().child(&#39;/posts/&#39; + newPostKey).set(postData);
        firebase.database().ref().child(&#39;/user-posts/&#39; + uid + &#39;/&#39; + newPostKey).set(postData);
    }

So maybe the example from the docs should be updated, because now it looks like `update` and `set` do the exact same thing.

Kind regards,
Bene

Firebase update vs set

In our App we&#39;re using FCM, so Firebase analytics is also working. 
However, from the dashboard, we can only see top devices. 

[![enter image description here][1]][1]

Is there a way to see more details about devices?

- All the models
- All OS
- Region of all the devices?
  etc.

For instance, we want to verify whether some users are being tracked in analytics (by their models), but can&#39;t find anyway to do that.

How to see all device list in Firebase Analytics?

I&#39;ve seen some questions and answers about custom events for firebase analytics, but i just wanted to ask you a straight question so you can give me a straight answer :)

So, this is my method for logging:

    @Override
    public void logFeatureSelectedEvent(String categoryName, String actionName, String labelName) {
        Bundle bundle = new Bundle();
        bundle.putString(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        bundle.putString(EventTrackingKeys.EventTypes.ACTION, actionName);
        bundle.putString(EventTrackingKeys.EventTypes.LABEL, labelName);
        mFirebaseAnalytics.logEvent(EventTrackingKeys.EventAnalyticTypes.FEATURE_SELECTED_EVENT, bundle);
    }

with custom event/key names:
       
    String CATEGORY = &quot;category&quot;;
    String ACTION = &quot;action&quot;;
    String LABEL = &quot;label&quot;;
    String FEATURE_SELECTED_EVENT = &quot;feature_selected_event&quot;;

So, in my firebase console I only get event name &quot;feature_selected_event&quot;, without custom parameter names.. 
I&#39;ve seen some answers that i should call setUserProperty() method and register that user property in the User Properties tab of Firebase Analytics. 
Is this the right way to implement that method? :

       @Override
    public void logFeatureSelectedEvent(String categoryName, String actionName, long value) {
        Bundle bundle = new Bundle();
        bundle.putString(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        bundle.putString(EventTrackingKeys.EventTypes.ACTION, actionName);
        bundle.putLong(EventTrackingKeys.EventTypes.VALUE, value);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.ACTION, actionName);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.VALUE, value);
        mFirebaseAnalytics.logEvent(EventTrackingKeys.EventAnalyticTypes.FEATURE_SELECTED_EVENT, bundle);
    }

I am trying to test the implementation of my Firebase Analytics. In their [documentation][1] they state that: 

&gt; Enable debug mode by passing the -FIRDebugEnabled argument to the
&gt; application. You can add this argument in the application’s Xcode
&gt; scheme. When debug mode is enabled via -FIRDebugEnabled, further
&gt; executions of the application will also be in debug mode. In order to
&gt; return to default mode, you must explicitly disable the debug mode
&gt; with the application argument -FIRDebugDisabled.

Unfortunately I do not understand where it is that I set this scheme. In Android this was easy. Help would be appreciated.

Turning Firebase Analytics on on Xcode

In my android application, I have an Activity that has 3 or 4 fragments that can be attached in sequence based on some user or server events.

I would like to track all these fragments as screens in firebase.

So ideally, if possible, is there an API i can invoke in the onCreate of the fragments, and tell firebase that user is currently in fragment1, fragment2 or fragment3?
