Pod Install Error

[SurpriseMF3000]

Hello,
i have issues installing this package.
When i do "pod install" i get the error "...have the same architectures (i386) and can't be in the same fat output file".

Error:
xctoolchain/usr/bin/lipo: /var/folders/gp/zf5ylzvn7d326cwb67646j6c0000gn/T/tmp.8tza5xtA/.build/iphoneos/lib/libsecp256k1.a and /var/folders/gp/zf5ylzvn7d326cwb67646j6c0000gn/T/tmp.8tza5xtA/.build/iphonesimulator/lib/libsecp256k1.a have the same architectures (i386) and can't be in the same fat output file

...have the same architectures (i386) and can't be in the same fat output file

Podfile:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '14.7'

target 'btctransaction' do
use_frameworks!
pod 'BitcoinKit', '~> 1.1.0'

end

Without this package works everything fine.

Apple M1
MacOS: 11.5.2
Big Sur

Are there any solutions?

I solved it with excluding arch's in the Build settings.
