I have the same issue. Using the example from eskimo returns the same "error: Couldn't lookup symbols:" error in Playground.
XCode 13.2.1
macOS 11.4
Output:
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
