You can set the &quot;Build Active Architecture Only&quot; and &quot;Archs&quot; values from command line itself. We set ARCHS=&quot;armv7 armv7s&quot; ONLY_ACTIVE_ARCH=NO. 

&gt;Eg
&gt;
&gt;/usr/bin/xcodebuild ARCHS=&quot;armv7 armv7s&quot; ONLY_ACTIVE_ARCH=NO -workspace -scheme ......

This will free you from manually changing the values in your project settings.

In my case it was empty cell in the &#39;valid architectures&#39; on the target level which resulted in empty &#39;resolved&#39; cell.

That lead to empty &#39;valid architectures&#39; parameter and at the end linker error.

In HTML5 we currently have a `&lt;figure&gt;` element, defined like so ([W3C reference][1]) 

&gt; The figure element represents a unit of content, optionally with a caption, that is self-contained, that is typically referenced as a single unit from the main flow of the document, and that can be moved away from the main flow of the document without affecting the document’s meaning.


Recently a new element `&lt;picture&gt;` was proposed by the [Responsive Images Community group][2] and it was defined [in the reference][3] like so

&gt; The picture element used for displaying an image that can come from a range of sources (see srcset attribute). Which image the user agent displays depends on the algorithm for deriving the source image. 

Since the two descriptions seems to be not contradictory (and documentation on picture is on *draft* state yet) here my question: is it possible (technically and semantically) to have a nested `picture` inside a `figure` element, in this way?

    &lt;figure&gt;
       &lt;picture&gt;
          &lt;source ...&gt;
          &lt;source ...&gt;
          &lt;source ...&gt;
          &lt;img..&gt;
       &lt;/picture&gt;
    
       &lt;figcaption&gt;...&lt;/figcaption&gt;
    &lt;/figure&gt;

I&#39;ve found no references about it in specs. :\

Note: I&#39;m aware that no browser implements currently this element, I&#39;m just making some experiments with [jQuery picture][4]  

Thank you.

Use of &lt;picture&gt; inside &lt;figure&gt; element in HTML5?

I&#39;m following the Scala course on Coursera.
I&#39;ve started to read the Scala book of Odersky as well.


What I often hear is that it&#39;s not a good idea to throw exceptions in functional languages, because it breaks the control flow and we usually return an Either with the Failure or Success.
It seems also that Scala 2.10 will provide the Try which goes in that direction.

But in the book and the course, Martin Odersky doesn&#39;t seem to say (at least for now) that exceptions are bad, and he uses them a lot.
I also noticed the methods assert / require...

Finally I&#39;m a bit confused because I&#39;d like to follow the best practices but they are not clear and the language seems to go in both directions...

Can someone explain me what i should use in which case?

Running in Xcode is correctly, but when I want to use command line with 
   $ /usr/bin/xcodebuild -scheme projectA -workspace projectA.xcworkspace -configuration Debug clean build 

And come up with the following.

    === BUILD NATIVE TARGET projectA OF PROJECT projectA WITH CONFIGURATION Debug ===
    Check dependencies
    No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=armv7 armv7s).

In Build Settings are:

 - Architectures: Starndard (armv7, armv7s)
 - Base SDK: Latest iOS (iOS 6.0)
 - Build Active Architecture Only: Debug Yes, Release No
 - Valid Architectures: armv7 armv7s

After I change `Build Active Architecture Only = No`, then the build was BUILD SUCCEEDED.

What is the suggestion setting for this situation, to build success under commend line mode? Thanks.

I have a scroll view with content that is 1000px tall and would like to be able to lay it out for easy design on the storyboard.   
I know it can be done programmatically but I really want to be able to see it visually. Every time I put a scroll view on a view controller it won&#39;t scroll. Is it possible to get it to work like I want or do I have to do it in the code?

So for my new app I&#39;m having a URL scheme so that people can launch my app from another app or from a website... &quot;myapp://&quot;   ...   So what happens if there is another app in the AppStore that has the same URL scheme as mine? Or if someone tries to steal my URL Scheme?

I use quite a lot third party libraries which have many warnings in it, after the latest Xcode updates. (for example the Facebook SDK pod)
Now all these warnings are shown in my Xcode on the place I want to see my own warnings or errors. 

Is there any way to ignore these errors? Fixing them won&#39;t help, since after every &quot;pod install&quot; the changes are discarded.

Ignore Xcode warnings when using Cocoapods

I&#39;m writing ANSI-compatible C code, and hence I can&#39;t use the line (`//`) comment. I&#39;m using Xcode. In Sublime Text and Eclipse, and I think most other IDEs, there are separate keyboard shortcuts for line comments and block comments (`/**/`). However, I don&#39;t see that in Xcode - in fact, I don&#39;t even see a menu option to add a block comment. Is it simply not supported in Xcode? That would certainly seem to be a lame decision if so.

Is there a shortcut to make a block comment in Xcode?

I&#39;ve got a `UICollectionView`, which works ok, until I start scrolling.
Here some pics first:
![enter image description here][1]

As you can see it&#39;s great. As I start scrolling (paging enabled) the first one goes a bit offscreen:
![enter image description here][2]

This is the problem. Originaly my view have 3 views and I want to scroll and show 3 views only. But as it scrolls (paging enabled) it hides a little bit of the first view and show little bit of the next first view from the next page. 


 And here is a video, because it&#39;s kinda hard to explain:

I have a curios issue. 

I have a project that I&#39;ve worked on and always built from the XCode IDE, and it worked fine. Now I&#39;m setting up Bamboo to build the project and as such am building it from the command line.

The issue is, if I check my code out of GIT and then use xcodebuild to build it it says that the scheme cannot be found, but if I open the project, it builds and if I then try to build it again from the command line with the same command, it works.

What magic is XCode doing when I open the project or am I doing something dumb, maybe excluding a file in my .gitignore that I shouldn&#39;t?


xcodebuild says does not contain scheme

I downloaded Xcode 6 GM and submitted two Swift apps to the app store today.  Both passed all pre-upload verification and all the other stuff they had to pass and were successfully submitted.  But then I got two emails from Apple... one for each program and they both said this:

&gt; Dear developer,
&gt;
&gt; We have discovered one or more issues with your recent delivery for &quot;xxxxxxxx&quot; (my app name removed). Your delivery was successful, but you may wish to correct the following issues in your next delivery: 
&gt;
&gt; Too many symbol files - These symbols have no corresponding slice in any binary [1431D977-72BC-308F-AB71-71529F25400B.symbols, 158C72A7-98AC-3F07-B2BE-88427591B413.symbols, 44973EAC-563E-340C-B549-55A5014A68BA.symbols, 678BF06F-0C3D-3A09-BFBF-699C7079FECD.symbols, 90907DDB-0400-38ED-BB5F-0C12333C0624.symbols, 93B79949-5757-374A-97B9-825AE1A61B7D.symbols, ABA05220-4FB0-397F-AFBB-08774A82F4CA.symbols, AD70F02A-4422-32B8-8C40-CF9B45A2CCC6.symbols, B0CC9F7D-C542-3E18-A518-B28B7ECABE80.symbols, BF6A4C3B-6FA5-3C51-8404-19C2F132458D.symbols, C9D6E078-8E2A-39D9-8DEE-476916A69CEE.symbols, CF5320DF-AB31-3845-BAD5-F6E51045D396.symbols, D4967AA3-8FB0-3712-B0DE-7F4144AF8F4B.symbols, D813B314-AD37-31D4-B675-442052994495.symbols, DF42A13F-08D8-3E71-B221-FC357E0B60F5.symbols, F5F636C2-F0E0-3CA7-8F7D-C49A36CD5C65.symbols]

&gt; After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.

I&#39;m going to guess that really has nothing to do with me or my apps... and it is just a quirk of day one Swift app submissions?  Both apps are still sitting in &quot;Waiting for approval&quot; mode.  I certainly can&#39;t think of anything I could change to make what they said go away!  Anyone else submit a Swift app yet and get that response?  Think I should just ignore it and wait to see what happens?

&quot;Too many symbol files&quot; after successfully submitting my apps

I want to replace my CI bash scripts with swift.  I can&#39;t figure out how to invoke normal terminal command such as `ls` or `xcodebuild`

    #!/usr/bin/env xcrun swift
    
    import Foundation // Works
    println(&quot;Test&quot;) // Works
    ls // Fails
    xcodebuild -workspace myApp.xcworkspace // Fails

---

    $ ./script.swift
    ./script.swift:5:1: error: use of unresolved identifier &#39;ls&#39;
    ls // Fails
    ^
    ... etc ....

How do I run a terminal command in a Swift script? (e.g. xcodebuild)

I just configure a project in bitrise.io. But the xcode-build fails with error:

    xcodebuild: error: The project named &quot;Foo&quot; does not contain a scheme named &quot;Bar&quot;. The &quot;-list&quot; option can be used to find the names of the schemes in the project.

I double check and the scheme **Bar** does exist in the project **Foo**
