I create new plugin by static libraries;
he have three file. jcore-ios-1.1.5.a jpush-ios-3.0.6.a and JPUSHService.h.
tns run ios show error
Processing node_modules failed. Exception: The static library at /Users/feng/AnBangCrmApp/node_modules/nativescript-jpush/platforms/ios/jcore-ios-1.1.5.a is not built for one or more of the following required arch
itectures: armv7, arm64, i386. The static library must be built for all required architectures.

lipo -info show

@xiaochong44 the static library you are using is not build for all required architectures and you are trying to build for architecture that is missing (e.g. you are building on real device that requires armv7 but the static library is build only for i386).
What you need is to create a fat static library - see this thread for more information on the topic.

@NickIliev
Thanks for you message.
This static library is provided by other companies
He is a push service, I386 is before IPhone5 ,The simulator is already x86_64, is there a setting that can not check i386?

@xiaochong44 for real devices your static library needs to be built for armv7, arm64,

It should have armv7 arm64？

@xiaochong44 The CLI checks each library against a list of required architectures and fails if the binary doesn't contain even one of them. Currently, the list contains armv7, arm64 and i386 archs. However, it is a perfectly valid scenario to include a library containing only device architectures (armv7, arm64) so IMO the current behaviour is buggy. Ideally, we should check for existence only those archs we are building for. This way, building for release won't fail because of missing simulator architecture. I am reopening the issue and tagging it as bug.

To workaround the problem you can merge your existing jcore-ios-1.1.5.a binary with an empty i386 library. Open Xcode and create an empty static library target and run a build for i386 arch. The produced binary can be merged with the existing library:

lipo -create jcore-ios-1.1.5.a my_dummy_i386_lib.a -output  jcore-ios-1.1.5-fat.a

This way, the library still won't work on simulators because the i386 slice doesn't contain any symbols but it is enough to make the CLI check pass.
