Failed to build module 'WalletCore'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.7 (swiftlang-5.7.0.127.4 clang-1400.0.29.50)', while this compiler is 'Apple Swift version 5.7.1 (swiftlang-5.7.1.135.3 clang-1400.0.29.51)'). Please select a toolchain which matches the SDK.
