iOS 14 changes to Combine?

Forums > Swift

Were there any changes to combine in iOS 14? I started running my app in iOS 14 on Xcode beta and began seeing some new errors - does iOS 14 require codingkeys now even if keys are the same from imported JSON?

failure(Swift.DecodingError.keyNotFound(CodingKeys(stringValue: "id", intValue: nil), Swift.DecodingError.Context(codingPath: [_JSONKey(stringValue: "example text", intValue: nil), CodingKeys(stringValue: "quote", intValue: nil)], debugDescription: "No value associated with key CodingKeys(stringValue: \"id\", intValue: nil) (\"id\").", underlyingError: nil)))

   

Ah this was the result of xcode telling me not to set "let id = UUID()" in my struct: "Immutable property will not be decoded because it is declared with an initial value which cannot be overwritten"
