Facebook sdk is compiling on my IOS device, but no my simulator

Question

I've downloaded the Facebook SDK, and gotten it to work on the simulator to post from my app, but it won't even compile on my device.

 clang: error: no such file or directory: '/Users/justking14/Library/Developer/Xcode/DerivedData/Descover-fqkbngyllggoxkcskmhhzgmkffxe/Build/Products/Debug-iphoneos/libPluginFacebook.a'
 clang: error: no such file or directory: '/Users/justking14/Library/Developer/Xcode/DerivedData/Descover-fqkbngyllggoxkcskmhhzgmkffxe/Build/Products/Debug-iphoneos/libPluginProtocol.a'

libPluginFacebook.a and libPluginProtocol.a are in red in the Link Binary with Libraries, and when I remove them it still won't compile saying

 ld: file is universal (4 slices) but does not contain a(n) armv7s slice: /Users/justking14/Desktop/IR/cocos2d/plugin/plugins/facebook/proj.ios/sdk/FacebookSDK.framework/FacebookSDK file '/Users/justking14/Desktop/IR/cocos2d/plugin/plugins/facebook/proj.ios/sdk/FacebookSDK.framework/FacebookSDK' for architecture armv7s
 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

The FacebookSDK you use doesn't have machine code for the architecture armv7s

That architecture WAS top of the line but now, apps mostly only use armv7 and arm64

---

Change your app build settings to only use those architectures (just use the default)
