build fail xcode 10 error : symbol(s) not found for architecture x86_64 using Cocoapods ( with screen and config )

Question

i'm new to xcode and cocoapods, i try to run my app ((Using angular & ionic)My app worked fine before adding cocoapods ) to implement push notification with FCM and my build fail with the error message below, i've searched a lot on google and here in stackoverflow but none of the proposed solutions worked for me. I've tried :

added $(ARCHS_STANDARD_INCLUDING_64_BIT) to the Architectures
build active architecture only -> set to 'NO'
for 'valid architectures' -> set to arm64, armv7 and armv7s
deleted the DerivedData folder and its contents, cleaned and built again
So many 'Clean Build Folder'
Tried with and without use_frameworks! in Podfile
deintegrating and reintegrating pods.

Sometime the error message change to "library not found for -lPod-Myionic AppName", i guess both errors are linked , but i dont understand why, maybe my Podfile is not set properly ?

Thanks for your help.
