ANE Packaging with IOS11

Question

i have devloped an ANE that connects to a bluetooth printer in order to print ,this ane was working perfectly until IOS 11 has been publish now what i see in the log is that the printer connects but cant print i updated the xCode to support ios 11 and updates the air to 27 and compiled the new ane and the swc also compiled in air 27

now when i try to publish the app i got this msg " Error occurred while packaging the application:

Error: META-INF/ANE/iPhone-ARM/libCoreMobileAPI.a, META-INF/ANE/iPhone-ARM/libZebraChecker.a are required to have universal iOS libraries. Please contact the ANE developer(s) to get the same."

This ANE works only for IOS

iam sure that i have chosen universal iOS when i build the .a file anyone has solution or can give me hints what to do thanks

In Architectures settings of your target make sure you have your settings as below. Important parts are the "Valid Architectures" and the "Build Active Architecture Only" settings.

If that doesn't work make sure that you are using the correct .a file. You can run the following command on the .a file:

file libZebraChecker.a

It should output something like the following if it is a universal binary:

libZebraChecker.a: Mach-O universal binary with 2 architectures: [arm_v7: current ar archive] [arm64: current ar archive]
libZebraChecker.a (for architecture armv7): current ar archive
libZebraChecker.a (for architecture arm64): current ar archive
