Apple Mach-O Linker Errors Xcode

Question

I got this Error from Xcode when trying to run my app on my device.

Ld "/Users/admin/Library/Developer/Xcode/DerivedData/Store_Locator_In_App-hbygxaouhvxmvwdudbwamekfbima/Build/Intermediates/Store Locator In App.build/Debug-iphoneos/Store Locator In App.build/Objects-normal/armv7s/Store Locator In App" normal armv7s

ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /Users/admin/Desktop/peboom 5/libGoogleAnalytics_NoThumb.a for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Answer 1

The new iPhone 5 processor has a custom ARMv7 core which uses a new architecture called armv7s .

The linker is returning that error because the armv7s slice is missing from the libGoogleAnalytics_NoThumb library you're referencing in your project.

Simply update the GoogleAnalitics SDK to the latest version (1.5.1) you can download here: https://developers.google.com/analytics/devguides/collection/ios/resources
