@tristanhimmelman, do you have plans to resolve these error, or you prefer working on the new version with Alamofire 5?

[RomanPodymov]

Hello @TrabelsiAchraf
What AlamofireObjectMapper version are you using?

[TrabelsiAchraf]

@RomanPodymov Version 5.2

[RomanPodymov]

@TrabelsiAchraf What about v.5.2.1?

[o15a3d4l11s2]

@RomanPodymov I have used v5.2.1 prior to posting here and I get the same error.

[RomanPodymov]

@TrabelsiAchraf @o15a3d4l11s2 Cannot reproduce the issue on my side. Which Alamofire and ObjectMapper versions are you using? How do you install dependencies?

[TrabelsiAchraf]

@RomanPodymov I use the Alamofire 4.9.1 with AlamofireObjectMapper 5.2.1. And for dependencies I use cocoapods. Not working always.

[RomanPodymov]

Hello @TrabelsiAchraf
And what ObjectMapper version are you using?

[epitonium]

The same. Alamofire 4.9.1, ObjectMapper 3.5.0, AlamofireObjectMapper 5.2.1

[RomanPodymov]

Hello @TrabelsiAchraf @epitonium @o15a3d4l11s2 @JasonMR7
Could you please share an example where I can reproduce the issue?

[o15a3d4l11s2]

@RomanPodymov , I am using the following:

• Cocoapods for installing the libraries
• Alamofire v4.9.1 (I do not want to use Alamofire v5 yet)
• AlamofireObjectMapper v5.2.1 (because of Alamofire v4 support)
• ObjectMapper v3.5.1
• Xcode v11.3.1
• Swift Language Version v5

Error that I get:

Ambiguous use of 'map(JSONObject:)'

from AlamofireObjectMapper.swift, line 109
and

Ambiguous use of 'mapArray(JSONObject:)'

from AlamofireObjectMapper.swift, line 167

I explicitly set the Swift Language Version to v5 for AlamofireObjectMapper pod project. The reason is that I want all projects using Swift 5, so I no longer get the warning that there are projects to migrate to Swift 5.

Sorry for the late answer, I was pretty busy last week. Now I am able to answer faster.

Hello @o15a3d4l11s2
Thanks for the clarification. However, I still cannot reproduce the issue on my Mac. Could you please share a simple project that I can use to reproduce the issue?

[o15a3d4l11s2]

This is just a dummy Single View project with the pods pre-installed and Swift version set to 5 in the AlamofireObjectMapper pod.

Could you please share it on GitHub?

Fixed in #300, for now use pod 'AlamofireObjectMapper', :git => 'https://github.com/RomanPodymov/AlamofireObjectMapper.git', :branch => 'xcode-10-2-fix' in your Podfile.

Hi, I used to pod 'AlamofireObjectMapper', '5.2.1' but I still got an error

• Ambiguous use of 'map(JSONObject:)'
  I used to Xcode 11.3.1, swift 5
  Can you support me
  Thank!

[RomanPodymov]

Hello @dodangduong
As I already mentioned, replace pod 'AlamofireObjectMapper', '5.2.1' with pod 'AlamofireObjectMapper', :git => 'https://github.com/RomanPodymov/AlamofireObjectMapper.git', :branch => 'xcode-10-2-fix' in your Podfile.

If my project used swift 4.2 it's work but I set my project is swift 5 I still got an error Ambiguous use of 'map(JSONObject:)'.

Hello @dodangduong
Could you please share on GitHub a project where I can reproduce the issue that you have?

[thongdn-it]

Hi @dodangduong
You can try to replace pod 'AlamofireObjectMapper', '5.2.1' with pod 'AlamofireObjectMapper', git:'https://github.com/thongdn-it/AlamofireObjectMapper.git'

I tried in my project and it works

Alamofire (5.0.5)
AlamofireImage (4.0.3)
AlamofireObjectMapper (6.3.0)

[o15a3d4l11s2]

@thongdn-it, this specific issue is for an older version of AlamofireObjectMapper that is used in conjunction with Alamofire 4.
