ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have already tried everything to make It work again and everything I read on stack overflow from other posts who face a similar issue

-reinstall pod
-update pod
-new podifle
-removing target
-deleting derived data
-cleaning project
-restarting simulator
-restarting Xcode

i don’t even know what I have changed to make this problem appear, never faces this issue before

any help is appreciated!

    The error came by me accidentally deleting code in the pod file, which I was not aware of.

    deleting the pod and moving it back in did not help

    halt helped was

    pod deintegrate
pod install

    W/o sample project we can only guess what did you make wrong.

    So my guess…
    If you updated to Xcode 12 – go to project settings, scroll to the bottom User-Defined section and remove VALID_ARCHS setting. If you don’t have it there – then my guess was wrong and I wish you good luck :D.

    UPD:
