iPhone library: file is not of required architecture

Answer 1

You need to compile your library for Intel so the Simulator can use it (which I gather you have done already), and then compile it for ARM, so it can run on the iPhone. Then you have to merge the two libraries. There are different ways to accomplish that, or make it more automatic.

Here are some links to help you:

Answer 2

You need to add both .a files,the one built for the device (build/$config-iphoneos)and the one built for the sim (build/$config-iphonesimulator) to the new project. Make sure you name them differently before dropping them in. This is how admob and similar offering ship their static libs.

Answer 3

I meet the same problem too. But seems you don't need to drag two .a file into the app project to solve this proplem. This is what I do: 1. Drag the static library project into app project's framework group 2. "Get Info" for the target in app project 3. Set the direct dependcy of static library 4. Make clean all unnecessary builds(for example the simulator build) in the static library project 5. Build in the app project
