This is the error I get
Invalid data: typeMismatch(Swift.Double, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "Services", intValue: nil), _JSONKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "NextBus", intValue: nil), CodingKeys(stringValue: "EstimatedArrival", intValue: nil)], debugDescription: "Expected to decode Double but found a string/data instead.", underlyingError: nil))
When I try to print the estimatedArrival in the SwiftUI View as a Text() converted from the date format 2022-08-29T12:06:28+08:00 which is in "yyyy-MM-dd’T’HH:mm:ssZ" format.
However when I change to estimatedArrival: String instead of Date, it doesn't the error anymore.

Thank you for reading through this! I appreciate your help!
