[iOS] App crash when trying to upload file with alamofire 5

[paszek]

Mobile iOS app is distributed through global App Store but as private app shared with an organization.
Corporate user is authorized by NTLM properly and can use app until it crashes which happens when its trying to upload file to server.
That file is a photo that is taken (by the same app) right before upload.
Upload is implemented with Alamofire method AF.upload.
When MAMSDK is not initialized at app start, there is no crash during upload (in dev env).
Other HTTP requests work without errors.
App worked with Alamofire 4 but I had to migrate to Alamofire 5.

As You will see in crash logs there is call to Alamofire from CTXMAMNetwork
I'm dev outside of organization and I don't have access to prod env where MAMSDK works with Citrix stack.
Crash log was sent to me by organizations user.

Apart from latest MAMSDK for iOS 25.3.0.1 there are dependencies:

• Alamofire (~> 5.9.0)
• DLRadioButton (~> 1.4)
• Firebase/Core (~> 10.22.0)
• Firebase/Messaging (~> 10.22.0)

Hi @paszek

• Alamofire is not supported​​ in the MAM SDK environment, the relevant http/https requests will not be intercepted by MAM SDK.
• ​​Recommended Solution:​​ Use native URLRequest with URLSession for network requests instead.
