Xcode 4 introduces schemes which provide all the options on how to build/run/profile/etc. your application. You can change the active scheme using the `Scheme` drop-down button at the top of the project window and/or edit the scheme via `Product &gt; Edit Scheme… ⌘&lt;` menu item.  Then on the left source list, you can select the `Run` item, and in the `Info` tab in the right pane you can choose to use the `Release` configuration in the `Build Configuration` drop-down.

In Xcode 4.3 -- go to Product/Build For and select Archiving.  This compiles a release build and places it in an obscure folder which you&#39;ll never find on your own.  The quickest way to get there is to select your app in Xcode&#39;s project navigator (in the Products folder), right-click, select Show in Finder.  It will take you to the debug build but the release build is in a folder right next to it.

To add to Adam Bryzak answer, you need to activate the DEBUG and release (and adhoc if needed) in the build settings settings.

Under project/Build settings, search for Preprocessor Macros and set the Debug and release values to 1 in order to activate them:

This way, in the edit schemes, when you switch between DEBUG and release, Xcode will know that he should to change the build mode.

How does the [`ILookup&lt;key, value&gt;`][1] interface differ from [`IDictionary&lt;key, value&gt;`](http://msdn.microsoft.com/en-us/library/s4ys34ea.aspx)?

I don&#39;t understand what the [`ILookup`][1] interface is meant for.

I am trying to pass an arrayList to another activity using intents. Here is the code in the first activity.

    case R.id.editButton:
			Toast.makeText(this, &quot;edit was clicked&quot;, Toast.LENGTH_LONG).show();
			Intent intent = new Intent(this, editList.class);
			intent.putStringArrayListExtra(&quot;stock_list&quot;, stock_list);
			startActivity(intent);
			break;

This is where I try to retrieve the list in the second activity. Is something wrong here?

    Intent i = new Intent(); //This should be getIntent();
		stock_list = new ArrayList&lt;String&gt;();
		
		stock_list = i.getStringArrayListExtra(&quot;stock_list&quot;);

I see how Xcode 4 splits the info on your targets nicely in one view, but how does one build and run these different builds? All I see are the options to build and to run, and these options to build for running, testing, and profiling. It&#39;s not clear to me how these map to the build configurations, though.

I tried to add my iPhone to Xcode4 to test my Application on it. I added the device in the Apple Developer-Center and downloaded the Provision-Profile. We pay 99$ per month for the account and I&#39;m not the only person who use this account. So there is already an &quot;older&quot; certificate present which I tried to add to my keychain-manager. But I see a red-text above it (translated from german) &quot;This certificate has been signed by an unknown instance.&quot;.

In my XCode-Device Manager in the Provisioning-Section there&#39;s also an error: &quot;XCode could not find a valid private-key/certificate pair for this profile in your keychain.&quot;

I really don&#39;t understand what I have to do now. These keys may really not exist in my keychain, I can&#39;t find them. So how I have to create them know and how can I use them if there is already one certificate in the Apple Dev-Center?

Xcode - iPhone - profile doesn&#39;t match any valid certificate-/private-key pair in the default keychain

Not a long time ago I updated Xcode to version 4. This new version spent a lot of time on indexing the project (it&#39;s quite large). That&#39;s why I would like to disable indexing.  Searching through Xcode help and internet gave no results.

How to disable indexing in Xcode 4?

I am running a &quot;old&quot; Xcode 3 project in Xcode 4 and code sense is not working for my own classes. I have tried following:  

 - Clean/rebuild
 - Remove Derived Data
 - Installing 4.3 documentation
 - Restart

Without any luck.

Sometimes the code sense works but mostly I just get &quot;No Completions&quot;.

I understand exactly why unused variable warnings occur. I don&#39;t want to suppress them in general, because they are incredibly useful in most cases. However, consider the following (contrived) code.

    NSError *error = nil;
    BOOL saved = [moc save:&amp;error];
    NSAssert1(saved, @&quot;Dude!!1! %@!!!&quot;, error);

Xcode reports that `saved` is an unused variable, when of course it isn&#39;t. I suspect this is because `NSAssert1` is a macro. The `NS_BLOCK_ASSERTIONS` macro is _not_ defined, so Objective C assertions are definitely enabled.

While it doesn&#39;t hurt anything, I find it untidy and annoying, and I want to suppress it, but I&#39;m not sure how to do so. Assigning the variable to itself gets rid of the compiler warning, but I&#39;d rather do it the &quot;right&quot; way if such a thing exists.

How can I get rid of an &quot;unused variable&quot; warning in Xcode?

I know there is something like `find_package(Threads)` but it doesn&#39;t seem to make a difference (at least by itself). For now I&#39;m using `SET(CMAKE_C_FLAGS ${CMAKE_C_FLAGS} &quot;-pthread&quot;)`, but it doesn&#39;t look like a correct solution to me.

I believe I&#39;ve followed the instructions in the Android SDK, and I&#39;m now trying to build the sample LunarLander (random one picked)

    $ cd samples/android-11/LunarLander
    $ ant debug
    Buildfile: build.xml does not exist!
    Build failed

I believe all PATHs are setup correctly. 
I&#39;ve done this before in an older Android SDK release and I know I didn&#39;t encounter this error, so I&#39;m pretty confused as to what&#39;s wrong.  

Oh, one more piece of info -- I have only installed the 3.0 platform package, so I&#39;m not sure if that is an error or not.

I struggled finding a how-to which provides a stable solution for using Qt with Visual Studio 2010, so after collecting all the bits of information and some trial and error, I would like to write my solution into a guide.

The problem, or why is it not possible to use prebuilt binaries?
-------------------------------

It seems that using binaries built for Visual Studio 2008 might work in some special cases, but I found them not to work. In my case they compiled OK, but they produce runtime errors, like this:

![problem2][9]

or when started from Visual Studio 2010:

![problem][10]

**Update**: I found a blog post analysing why does it work for some people, while it does not for others. In one word, it depends on whether you have Visual Studio 2008 installed on the same machine, or not.
http://blog.paulnettleship.com/2010/11/11/troubleshooting-visual-studio-2010-and-qt-4-7-integration/

&gt;  The most important thing (that I stupidly didn’t realize) was the fact that you CANNOT use the Visual Studio 2008 compiled libraries and dll’s (available on the Qt webpage) if you don’t have Visual Studio 2008 installed. The reason is because the Qt SDK you download is a debug build which is dependant on the VC9.0 DebugCRT, meaning it needs the Visual C++ 2008 Debug Runtime installed, which is NOT available as a redistributable installer. The only way to install the DebugCRT is to install the entirety of Visual Studio 2008.

I have a multi-project configuration and I want to use gradle.

My projects are like this:

- Project A
    - -&gt; `src/main/java`
    - -&gt; `src/test/java`

 
- Project B  
    - -&gt; `src/main/java` (depends on `src/main/java` on **Project A**)  
    - -&gt; `src/test/java` (depends on `src/test/java` on **Project A**)  

My **Project B** `build.gradle` file is like this:

    apply plugin: &#39;java&#39;
    dependencies {
      compile project(&#39;:ProjectA&#39;)
    }

The task `compileJava` work great but the `compileTestJava` does not compile the test file from **Project A**.

Why is it that when I build an application, Xcode creates a debug build? I want to create a release build. How can I do this?

How do I create a release build in Xcode?

Shutting off *my own* app&#39;s LogCat output before releasing an app to the market is straightforward. I also know how to selectively filter LogCat message by tag and/or id for my own debug convenience.

But now I am interested in something that may be much more difficult (perhaps impossible?): Disable all LogCat output, including &amp; especially those coming from 3rd-party services like TtsService, GoogleLoginService, etc.

Is this possible?

To further clarify: I am *not* interested in filtering out messages for myself. I am rather interested in disabling 3rd-party messages for whoever downloads my app from the Android Market. Is this possible?


Disable LogCat Output COMPLETELY in release Android app?

When I use Application Loader, I get to the point where it asks me to &quot;Choose...&quot; the file to be uploaded.

If I understand correctly, it supposes to be the appName.app file I see under &quot;Products&quot; on my app bundle (I right click it and select &quot;Show in Finder&quot; to get to the specific file in library; then I&#39;m supposed to ZIP it and the ZIP file is what I will choose in Application Loader). First, am I correct with this assumption?

if yes...

What should I define different in XCode than the way I used to build the application for testing (on simulator and on my personal iPhone)?

Should I change the **Info---&gt;Command-line build use** from **Debug** to **Release**?

How should I define the **Build Settings---&gt;Code Signing** section (in which field should I select the &quot;**iPhone Developer**&quot; option and in which should it be &quot;**iPhone Distribution**&quot;)?

Are there any other important Info/Build Settings/p.list/etc... fields I should relate to?

any help will be appreciated...

How to Create the Upload File for Application Loader?

I am making an app that processes sensitive credit card data.

If my code is running in debug mode I want to log this data to the console and make some file dumps.   

However on the final appstore version (ie when it is running in release mode) it is essential all of this is disabled (security hazard)!

I will try to answer my question as best I can;  so the question becomes *&#39;Is this solution path the right or best way to do it?&#39;*
  
    // add `IS_DEBUG=1` to your debug build preprocessor settings  
  
    #if( IS_DEBUG )  
    #define MYLog(args...) NSLog(args)  
    #else  
    #define MYLog(args...)  
    #endif  



How to determine whether code is running in DEBUG / RELEASE build?

Currently, I package the release builds with Nuget for the official builds to nuget.org, but I package the debug builds with Nuget for the symbol source pushes to symbolsource.org.

EDIT: (Jon Skeet, with some bias from Noda Time development)

NuGet now supports pushing to both NuGet gallery *and* symbolsource.org (or similar servers), [as documented][1]. Unfortunately, there are two contradictory requirements here:

- When just *using* a library without any need for debugging, you really want a release build. That&#39;s what release builds are for, after all.
- When debugging into a library for diagnostic purposes, you really want a debug build with all the appropriate optimizations disabled. That&#39;s what debug builds are for, after all.

That would be fine, but NuGet doesn&#39;t (as far as I can tell) allow both the release and debug builds to be published in a useful way, in the same package.

So, the choices are:

- Distribute the debug builds to everyone (as shown in the example in the docs) and live with any size and performance hits. 
- Distribute the release builds to everyone and live with a slightly impaired debug experience.
- Go for a really complicated distribution policy, potentially providing separate release and debug packages.

The first two really boil down to the effect of the differences between debug and release builds... although it&#39;s worth noting that there&#39;s also a big difference between wanting to step into the code of a library because you want to check some behaviour, and wanting to debug the code of a library because you believe you&#39;ve found a bug. In the second case, it&#39;s probably better to get the code of the library *as a Visual Studio solution* and debug that way, so I&#39;m not paying too much heed to that situation.

My temptation is to just keep with the release builds, with the expectation that *relatively* few people will need to debug, and the ones who do won&#39;t be impacted *much* by the optimizations in the release build. (The JIT compiler does most of the optimizing anyway.)

So, are there other options we hadn&#39;t considered? Are there other considerations which tip the balance? Is pushing NuGet packages to SymbolSource sufficiently new that &quot;best practice&quot; really hasn&#39;t been established?
