如何解决下面提到的错误？
ld: warning: URGENT: building for iOS simulator, but linking in object file (/Users/amy/Desktop/amy/swift_proj/swift_proj/include/libcrypto_x86_64.a(asn1_lib.o)) built for OSX. Note: This will be an error in the future.
我假设要在iPhone模拟器上运行，我们使用拱门类型x86_64。那是对的吗？我要链接的库（libcrypto）的类型为x86_64。
我在下面显示了我的Xcode构建设置：
Architectures: Standard architectures
Base SDK: Latest iOS (iOS 11.4)
Build active architecture only: No
Supported platforms: iOS
Valid architectures: arm64
我是新手。
