'Method' is ambiguous for type lookup in this context, Error in Alamofire

Question

I am using Alamofire for network handling in swift and run into one weird error. It seems like we can't pass Method enum as parameter.
[Error is on Method parameter]

private func apiRequest(method: Method, url: String, apiData: [String : AnyObject], completion:(finished: Bool, response: AnyObject?) ->Void) {

    Alamofire.request(method, url, parameters: apiData).responseJSON{ response in
        if let JSON = response.result.value {
            completion(finished: true, response: JSON)
        } else {
            completion(finished: false, response:nil)
        }
    }
}

Answer 1

You have to specify the module from which to lookup object type. Call Alamofire.Method

Answer 2

There is probably a name collision. To solve it, you can use the qualified name of the enum (including the module name):

private func apiRequest(method: Alamofire.Method, ...

Answer 3

I have also encountered this problem, because I have declared a number of the same name of the protocol:

protocol SomeProtocol {
   static func someTypeMethod()
}

protocol SomeProtocol {
   init(someParameter: Int)
}

protocol SomeProtocol {
   var mustBeSettable: Int { get set }
   var doesNotNeedToBeSettable: Int { get }
}

You may have a class declared in two or more places in your application. The error is saying that there is no conclusive way to use this class because there are a couple different places in the code it is declared.

Answer 5

Swift 4 and Alamofire 4.7

Replace HTTPMethod to Alamofire.HTTPMethod

Answer 6

While the answer to this did fix the build error; in my case, the file showing the warning was in two different frameworks so Xcode did not know where to look. This was not the intended behavior of our internal frameworks so I simply removed the copy I no longer wanted.

Answer 7

The type Method is declared in two imported modules. You have to specify the module from which to use the type. Use Alamofire.Method instead of Method.

Tip: If you are using the type often, you can create a type alias in your module (application):

typealias Method = Alamofire.Method

That way you will not need to prefix the type with Alamofire. any more.

Answer 8

Change the enum type name to different &...

• Use the $(inherited) flag, or
• Remove the build settings from the target.

Target - > building settings- >ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES, Value type is Boolean, click on the other, change the value to $(inherited) perform - pod update Done

then try to run Your project , error will gone ! (I have tried in my project)

enum 'XYZ'ButtonType {

}

Answer 9

I got this error because my database table name and model class name was same...Issue resolved by renaming model class name.
