Can't seem to get CryptoKit to import. Is there some other configuration setting, etc. I need to fix? I though all you need to do in a playground is the import statement. My code looks like this: import UIKit import CryptoKit let string = "Hello world" let data = Data(string.utf8) let digest = SHA256.hash(data: data) let hash = digest.compactMap { String(format: "%02x", $0)}.joined() print("The hash is \(hash)") Basically, I can't use any method from CryptoKit although when I was typing the import statement, soon as I typed 'Cr' I was prompted with the fill of 'CryptoKit'. It also working in an IoS project in Swift. So I know it's there. Just won't work in the playground. I get the following error message: error: Couldn't lookup symbols:   static CryptoKit.HashFunction.hash<τ_0_0 where τ_1_0: Foundation.DataProtocol>(data: τ_1_0) -> τ_0_0.Digest   static CryptoKit.HashFunction.hash<τ_0_0 where τ_1_0: Foundation.DataProtocol>(data: τ_1_0) -> τ_0_0.Digest   static CryptoKit.HashFunction.hash<τ_0_0 where τ_1_0: Foundation.DataProtocol>(data: τ_1_0) -> τ_0_0.Digest   static CryptoKit.HashFunction.hash<τ_0_0 where τ_1_0: Foundation.DataProtocol>(data: τ_1_0) -> τ_0_0.Digest   static CryptoKit.HashFunction.hash<τ_0_0 where τ_1_0: Foundation.DataProtocol>(data: τ_1_0) -> τ_0_0.Digest Appreciate any insights. Thanks
