I have found the answer on this alternative page of Google:

https://firebase.google.com/docs/analytics/ios/start

&gt; 1. In Xcode, select Product &gt; Scheme &gt; Edit scheme... 
&gt; 2. Select Run from the left menu. 
&gt; 3. Select the Arguments tab. 
&gt; 4. In the Arguments Passed On Launch section, add -FIRAnalyticsDebugEnabled.

I wish Google would stop releasing half baked products and documentation. Could save hundreds of thousands of hours worldwide


I tried editing scheme and adding parameters, https://firebase.google.com/docs/analytics/ios/start but it did not work for me. In addition, I added following code after configuring FirebaseApp, at AppDelegate, didFinishLaunchingWithOptions 

        FirebaseApp.configure()
        Analytics.setAnalyticsCollectionEnabled(true)

and it worked for me. I hope it helps you too.

I think you should check console log on XCode. Because I will show log

&gt; To enable debug logging set the following application argument: -FIRAnalyticsDebugEnabled (see https://help.apple.com/xcode/mac/8.0/#/dev3ec8a1cb4)

Check again, if you don&#39;t:

- Add key FirebaseCrashlyticsCollectionEnabled has value true in Info.plist 
- set key IS_ANALYTICS_ENABLED is true in GoogleService-Info.plist
- Make sure file GoogleService-Info.plist add will all targets and save in root project


I want to create a new Date object, with a specific date.
I thought of converting it from a specific string,  for example:

    let dateString = &#39;1968-11-16T00:00:00&#39;

How can I convert it to a date object **in typescript**?



**Update:**

I&#39;m asking for a solution **in Typescript** and not in Javascript, and in **Angular2**, not AngularJS (1.x)

How to convert string to Date in Angular2 \ Typescript?

Suppose I have a class library which I want to target netstandard1.3, but also use `BigInteger`. Here&#39;s a trivial example - the sole source file is `Adder.cs`:

&lt;!-- language: c# --&gt;

    using System;
    using System.Numerics;
    
    namespace Calculator
    {
        public class Adder
        {
            public static BigInteger Add(int x, int y)
                =&gt; new BigInteger(x) + new BigInteger(y);            
        }
    }

Back in the world of `project.json`, I would target `netstandard1.3` in the `frameworks` section, and have an explicit dependency on `System.Runtime.Numerics`, e.g. version 4.0.1. The nuget package I create will list just that dependency.

In the brave new world of csproj-based dotnet tooling (I&#39;m using v1.0.1 of the command-line tools) there&#39;s an [implicit metapackage package reference](https://github.com/dotnet/core/blob/master/release-notes/1.0/sdk/1.0-rc3-implicit-package-refs.md) to `NETStandard.Library 1.6.1` when targeting `netstandard1.3`. This means that my project file is really small, because it doesn&#39;t need the explicit dependency:

&lt;!-- language: xml --&gt;

    &lt;Project Sdk=&quot;Microsoft.NET.Sdk&quot;&gt;
      &lt;PropertyGroup&gt;
        &lt;TargetFramework&gt;netstandard1.3&lt;/TargetFramework&gt;
      &lt;/PropertyGroup&gt;
    &lt;/Project&gt;

... but the nuget package produced has a dependency on `NETStandard.Library`, which suggests that in order to use my small library, you need *everything* there.

It turns out I can disable that functionality using `DisableImplicitFrameworkReferences`, then add in the dependency manually again:

&lt;!-- language: xml --&gt;

    &lt;Project Sdk=&quot;Microsoft.NET.Sdk&quot;&gt;    
      &lt;PropertyGroup&gt;
        &lt;TargetFramework&gt;netstandard1.3&lt;/TargetFramework&gt;
        &lt;DisableImplicitFrameworkReferences&gt;true&lt;/DisableImplicitFrameworkReferences&gt;
      &lt;/PropertyGroup&gt;
      
      &lt;ItemGroup&gt;
        &lt;PackageReference Include=&quot;System.Runtime.Numerics&quot; Version=&quot;4.0.1&quot; /&gt;
      &lt;/ItemGroup&gt;    
    &lt;/Project&gt;

Now my NuGet package says exactly what it depends on. Intuitively, this feels like a &quot;leaner&quot; package.

So what&#39;s the exact difference for a consumer of my library? If someone tries to use it in a UWP application, does the second, &quot;trimmed&quot; form of dependencies mean that the resulting application will be smaller?

By not documenting `DisableImplicitFrameworkReferences` clearly (as far as I&#39;ve seen; I read about it [in an issue][1]) and by making the implicit dependency the default when creating a project, Microsoft are *encouraging* users to just depend on the metapackage - but how can I be sure that doesn&#39;t have disadvantages when I&#39;m producing a class library package?

What are the application implications of a netstandard library depending on a metapackage?

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.

How to set the tab bar badge with swift ? for example when I get new message  showing number 1 on the message icon !

How to set the tab bar badge with swift?

I&#39;m programmatically adding a UITapGestureRecognizer to one of my views:

    let gesture = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(modelObj:myModelObj)))
        
    self.imageView.addGestureRecognizer(gesture)

    func handleTap(modelObj: Model) {
      // Doing stuff with model object here
    }

The first problem I encountered was &quot;Argument of &#39;#selector&#39; does not refer to an &#39;@Objc&#39; method, property, or initializer.

Cool, so I added @objc to the handleTap signature:

    @objc func handleTap(modelObj: Model) {
      // Doing stuff with model object here
    }

Now I&#39;m getting the error &quot;Method cannot be marked @objc because the type of the parameter cannot be represented in Objective-C.

It&#39;s just an image of the map of a building, with some pin images indicating the location of points of interest. When the user taps one of these pins I&#39;d like to know which point of interest they tapped, and I have a model object which describes these points of interest. I use this model object to give the pin image it&#39;s coordinates on the map so I thought it would have been easy for me to just send the object to the gesture handler.

**UPDATE:**
Use structs and not classes. Struct is better in many ways has got an initializer of its own.

This is my model class. Is it possible to create the `init` method automatically? Everytime I have to initialize all the variables one by one and it costs a lot of time. 
    
    class Profile {
            
        var id: String
        var name: String
        var image: String
            
        init(id: String, name: String, image: String) {
            self.id = id
            self.name = name
            self.image = image
        }
    }

I want `self.id = id` and other variables to initialize automatically.

After searching for some references to figure it out, -unfortunately- I could not find useful -and simple- description about understanding the differences between `throws` and `rethrows`. It is kind of confusing when try to understand how we should use them.

I would mention that I am kind of familiar with the -default- `throws` with its simplest form for propagating an error, as follows:


    enum CustomError: Error {
        case potato
        case tomato
    }
    
    func throwCustomError(_ string: String) throws {
        if string.lowercased().trimmingCharacters(in: .whitespaces) == &quot;potato&quot; {
            throw CustomError.potato
        }
        
        if string.lowercased().trimmingCharacters(in: .whitespaces) == &quot;tomato&quot; {
            throw CustomError.tomato
        }
    }
    
    do {
        try throwCustomError(&quot;potato&quot;)
    } catch let error as CustomError {
        switch error {
        case .potato:
            print(&quot;potatos catched&quot;) // potatos catched
        case .tomato:
            print(&quot;tomato catched&quot;)
        }
    }

So far so good, but the problem arises when:

    func throwCustomError(function:(String) throws -&gt; ()) throws {
        try function(&quot;throws string&quot;)
    }
    
    func rethrowCustomError(function:(String) throws -&gt; ()) rethrows {
        try function(&quot;rethrows string&quot;)
    }
    
    rethrowCustomError { string in
        print(string) // rethrows string
    }
    
    try throwCustomError { string in
        print(string) // throws string
    }

what I know so far is when calling a function that `throws` it has to be handled by a `try`, unlike the `rethrows`. So what?! What is logic that we should follow when deciding to use `throws` or `rethrows`?

Despite having set constraints to all elements, including the vertical ones needed for the cell to calculate its height, auto-layout seems to be ignored: all cells are squeezed.

Here&#39;s a screenshot of the result and of the constraints in the storyboard:

[![enter image description here][1]][1]

[![enter image description here][2]][2]

In the VC that holds the tableView, here&#39;s the code in **viewDidLoad:**

    tableView.estimatedRowHeight = 120.0
    tableView.rowHeight = UITableViewAutomaticDimension

Commenting out the second line gives cells with a height of 120.0 but Autolayout is ignored as well.

----------

## Update ##

To simplify the interface, I&#39;ve left a single label with, as constraints:

 - Leading space to superview
 - Top space to superview
 - Fixed width and height (100 &amp; 100)
 - Bottom space to container margin to make sure that the cell has all vertical constraints to determine its height

And with this simplified interface, auto-layout is still not taken into account, which hints me that the problem did not come from badly set constraints.

In the Size Inspector, the row height is set on 120 and Custom is checked. The cell has the right custom class, the cell reuse identifier is correct.

I am very new to macOS, I just need a mac with Xcode to compile my app. However, with macOS Sierra, I have a problem with my USB that is not working anymore (i can&#39;t plug my ipad pro)

Under OSX el capitan my usb works great, but now the problem is that app store offer me to download the Xcode 8.3 only that can work only on Sierra (strange they offer you to download something not compatible with your system but doesn&#39;t matter, it&#39;s apple). so the only way i have is to download manually the xcode 8.2.1

Now my question, how to install the Xcode_8.2.1.xip I just downloaded? and in near future, if I need to update xcode (I guess downloading myself a new version), how will I do? Also where the preferences and configurations settings are saved? does these preferences will be lost on each update?

How do I handle situation, when user logs out of my application and I no longer want him to receive notifications to the device.

I tried

    FirebaseInstanceId.getInstance().deleteToken(FirebaseInstanceId.getInstance().getId(), FirebaseMessaging.INSTANCE_ID_SCOPE)

But I still receive the notifications to my device&#39;s `registration_id`.

I also made sure that this is the token I should delete:

    FirebaseInstanceId.getInstance().getToken(FirebaseInstanceId.getInstance().getId(), FirebaseMessaging.INSTANCE_ID_SCOPE)

or simply `FirebaseInstanceId.getInstance().getToken()`).

I also tried `FirebaseInstanceId.getInstance().deleteInstanceId()`, but then the next time I call `FirebaseInstanceId.getInstance.getToken` I receive null (it works on the second try).

I guess, after `deleteInstanceId` I could immediately call `getToken()` again, but it looks like a hack. And also there&#39;s [this answer][1] which states that it shouldn&#39;t be done, but it proposes deleting the token which apparently doesn&#39;t work.

So what is the right method to handle this?

I keep getting a sporadic error from Cloud Functions for Firebase when converting a relatively small image (2mb). When successful, the function only takes about 2000ms or less to finish, and according to Image Magick documentation should I should not see any problems.

I tried increasing the buffer size for the command, which isn&#39;t allows from within Firebase, and I tried to find alternatives to `.spawn()` as that could be overloaded with garbage and slow things down. Nothing works.

Hi I am trying to unit test while developing a simple web with AngularJS + Firebase, but I have a problem defining the spec and trying the test runner

myProject/test/spec/main.js :

    describe(&#39;Controller: MainCtrl&#39;, function() {
	
	var MainCtrl, scope
	
	beforeEach(module(&#39;MainApp&#39;));

	beforeEach(inject(function ($controller, $rootScope) {
		scope = $rootScope.$new();
		MainCtrl = $controller(&#39;MainCtrl&#39;, {
			$scope: scope
		})
	}));

	it(&#39;should....&#39;,function(){
		expect(true).toBe(true)
	})
	it(&#39;should2....&#39;,function(){
		expect(false).toBe(false)
	})
    });

result:

    PhantomJS 2.1.1 (Mac OS X 0.0.0) Controller: MainCtrl should.... FAILED

    to: Firebase: Firebase App named &#39;[DEFAULT]&#39; already exists

However, defining the spec once is not a problem. For example:

    })

I do not know why this is the reason I give a hint to me

When I run

`firebase deploy --only functions`

it reads the `index.js` file and updates all functions exported from that file. If on the previous deploy there was a function named `a`, and in the current deploy there is no such function, `a` will be deleted. 

In other words, the effect is the same as if all existing functions were deleted and then the all functions from the current `index.js` file were added.

Is it possible to add/update/delete individual functions?
