Xcode 5 1 - No architectures to compile for ONLY ACTIVE ARCH YES active arch x86 64 VALID ARCHS i386

Question

After updating to Xcode 5 1  I can no longer build my project for the 64-bit simulator  receiving this error    No architectures to compile for  ONLY ACTIVE ARCH YES  active arch x86 64  VALID ARCHS i386     These are my target build settings     I tried changing  Build Active Architecture  to No  as well as adding  i386  to the  Valid Architectures   unfortunately neither worked  Thanks for any suggestions

Try removing all previous architectures  i e  remove the ARCHS STANDARD setting  at the same time as you add i386 to the Architectures  This should change the active architecture to i386  I encountered a similar issue when I tried to build for armv7 by default  but it kept trying to build for arm64  I changed ARCHS STANDARD to ARCHS STANDARD 32 BIT  and this changed the active architecture chosen

I had the same error message after upgrading to XCode 5 1   Are you using CocoaPods   If so  this should fix the problem    Delete the  Pods  project from the workspace in the left pane of Xcode and close Xcode  Run  pod install  from the command line to recreate the  Pods  project  Re-open Xcode and make sure  Build Active Architecture Only  is set to  No  in the build settings of both the  Pods  project and your own project  Clean and build

Add  Architectures    ARCHS STANDARD INCLUDING 64 BIT   Valid architectures  arm64 armv7 armv7s

In acrhiecture - sometimes to support 6 0 and 7 0   we exlude arm64  In architectures -   acrchitecture - select standard architecture arm64 armv7 armv7s   Just below in Valid acrchitecture make user arm64 armv7 armv7s is included  This worked for me

My problem was that the Pods project was targeting OS X  despite my Podfile having platform  ios  I m using cocoapods 0 35 0 rc2   To fix it  select the Pods project in the project navigator  and check that the Pods PROJECT node  mind you  not the Pods target  is targeting iOS  That is  the architectures build settings should be    Architectures    ARCHS STANDARD  Base SDK  iOS 8 1 Supported Platforms  iOS Valid architectures    ARCHS STANDARD    I also wanted to build all architectures  so I added the following to the Podfile   post install do   installer       installer project build configurations each do  config          config build settings  ONLY ACTIVE ARCH      NO      end end

If you are using CocoaPods  the most likely problem is because your Pods project Build Settings for Build Active Architecture Only is set to Yes for Debug   The solution is simple  Change it to No   Similarly  change to No for your application project

I had to add the following i386 and x86 64 to Valid Architectures  I m running Xcode 7 2 and targeting iOS 8   I already had armv7  armv7s and arm64 in there and that was working in Xcode 6 4

Just add arm64 in valid architecture i hope it will work for you

I found that it was necessary to enter the architecture names by hand     I don t know why this was necessary  i e  why these values were not inherited from Xcode itself  But as soon as I did this  the problem went away

What you need to do is just set the ONLY ACTIVE ARCH to NO  at least works for me   Below is a screenshot for it       EDIT   As far as I know  please point it out if there s something wrong  thanks   if you set ONLY ACTIVE ARCH to YES  it means the Xcode will only build for the active architecture  which refers to the device that s active in Xcode currently   Seems Xcode s default setting is set Debug to YES  so it won t build binaries for other architectures when you only want to build for a special device that connected to your Mac   The reason failed to build might be that  the project does not support the architecture of the device you connected  So the best solution is to add the right architecture for your device  Below is a list for architectures  amp  the devices that support    ARMv8 ARM64  iPhone 6  iPhone 5s  iPad Air  Retina iPad Mini ARMv7s  iPhone 5  iPhone 5c  iPad 4 ARMv7  iPhone 3GS  iPhone 4  iPhone 4S  iPod 3G 4G 5G  iPad  iPad 2  iPad 3  iPad Mini ARMv6  iPhone  iPhone 3G  iPod 1G 2G   So why  set the ONLY ACTIVE ARCH to NO  works  Because the device can still run the binary that built for all architectures you added  pass the build   but will lose some performance  This s just a quick solution  but not best     Note  The more architectures you added  the bigger the binary will be generated  So it s good to choose right architectures for your project

To avoid having  pod install  reset only active arch for debug each time it s run  you can add the following to your pod file    Append to your Podfile post install do  installer representation      installer representation project targets each do  target          target build configurations each do  config              config build settings  ONLY ACTIVE ARCH      NO          end     end end

In Valid architectures  Select each entry  release  debug  and build and press backspace  It should work

I had similar issue  Got it solved by changing  Architecture  to    ARCHS STANDARD 32 BIT   in Build Settings for Project   Now  you have to select Standard architectures  armv7  arm64  -   ARCHS STANDARD  since apple recommends apps to be build on 64-bit architecture  Click   Apple document

Just in case  for anyone still encountering the issue despite following the above  check that the simulator you are running is also the supported one  I had mine specified to arm7 and arm7s but was trying to run the app on a 64 bit simulator

Add arm64 to the target s valid architectures  Looks like it adds x86-64 architecture to simulator valid architectures as well

I solved this problem using  Kjuly s answer and the specific line    The reason failed to build might be that  the project does not support the architecture of the device you connected    With Xcode loaded it automatically set my iPad app to iPad Air    This caused the dependancy analysis error   Changing the device type immediately solved the issue     I don t know why this works but this is a very quick answer which saved me a lot of fiddling around in the background and instantly got the app working to test  I would never have thought that this could be a thing and something so simple would fix it but in this case it did

I arrived at this question due to a problem with command line build for simulator in Xcode 7 2  In case anyone else gets here with the same issue  I will share the solution I found   Apparently there is a bug in Xcode 7 2 that causes xcodebuild to fail when trying to build for simulator  The solution is to specify the option  -destination   e g   xcodebuild -project TestBuildCmd xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -destination  platform iOS Simulator name iPhone 6  build   Update  The above example command will build a binary including the graphics for iPhone 6 only  If the binary is run on other simulators  the iPhone 6 graphics is scaled to the platform  A better workaround which contains all graphics for all platforms is to specify the parameter PLATFORM NAME iphonesimulator  for example   xcodebuild -project TestBuildCmd xcodeproj -scheme TestBuildCmd -sdk iphonesimulator -arch i386 PLATFORM NAME iphonesimulator build

I faced the same problem when running my app on iPad using xcode 5 1  It got resolved by removing armv7s from  valid architectures  and setting the  build active architectures only  value to No  Both these fields can be found in your app- targets- build settings- architectures
