I am facing issues while using init(from decoder: Decoder) in Model extension in different module.

I have model in Module 1 as below

public struct LabelModel {
    public var value: String?
}

And I have decodable extension in module 2

extension LabelModel: Decodable {
    enum CodingKeys: String, CodingKey {
        case value
    }

    public init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        value = try container.decodeIfPresent(String.self, forKey: .value) // error - 'self' used before 'self.init' call or assignment to 'self'
    } // error - 'self.init' isn't called on all paths before returning from initializer
}

I am facing 2 errors while adding model extension with decodable in different module.
Any suggestion will be helpful for me.
Thanks in advance.
