Swift4 JSONDecoderExpected to decode Dictionary but found an array instead [duplicate]

Answer 1

Here, JSON data is Array of Objects.

change

try decoder.decode(User.self, from: data)

to

try decoder.decode(Array<User>.self, from: data)

Example:

var users = [User]()

let data = """
[{"U_ID":"1","Email":"test","Password":"test","UserType":"Teacher"}]
""".data(using: .utf8)

do{
    users = try JSONDecoder().decode(Array<User>.self, from: data!)
}catch{
    print(error.localizedDescription)
}

print(users.first?.Email)
