a) change argument for all your security imports to keychain from -T to -A
security import ./scripts/certs/dist.cer -k ~/Library/Keychains/ios-build.keychain -A
b) after all imports execute command set-key-partition-list
security set-key-partition-list -S apple-tool:,apple: -s -k <keychainPass> <keychainName>
