Already reference this setting, but did not solve the problem.

Consider this line of your build transcript:

ld: warning: ld: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.0.dylib, missing required architecture arm64 in file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.0.dylib (3 slices)ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.dylib, missing required architecture arm64 in file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.dylib (3 slices)

It seems that your reference to the SQLite library is failing somehow. Let’s focus on the path in question, namely,

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.0.dylib

. Look at the same path in my copy of Xcode 7:

$ ls -lh /Users/quinn/Xcode\ 7.3.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3*
lrwxr-xr-x  1 quinn  admin    14B 27 Apr  2016 /Users/quinn/Xcode 7.3.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.0.tbd -> libsqlite3.tbd
-rw-r--r--@ 1 quinn  admin   7.3K  4 Mar  2016 /Users/quinn/Xcode 7.3.1.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/usr/lib/libsqlite3.tbd

There is no

libsqlite3.0.dylib

, there is only

libsqlite3.0.tbd

and

libsqlite3.tbd

. I’m not sure how your Xcode 7 managed to get an iOS 9.3 SDK that includes a

.dylib

rather than a

.tbd

, but that’s seems like the root of your problem. I recommend that you delete your current copy of Xcode 7 and download one afresh from the Downloads area on the developer web site; scroll all the way to the bottom and then click See more downloads to get to the archive where you’ll find older versions of Xcode.

Share and Enjoy
