Alamofire: Alamofire 5.2.2 TestFlight watchOS build crashes on Apple Watch Series 3 devices (32-bit) (Bitcode related?)

What did you do?

Hello!

I have a WatchOS Application on TestFlight that is crashing on startup on Apple Watch Series 3 devices (32-bit). It works flawlessly on Simulators (Xcode 11.7) and Apple Watch Series 4.

I am using Alamofire 5.2.2 with Swift Package Manager. Latest Xcode (version 11.7). The device is Apple Watch Series 3 devices (32-bit) running latest final watchOS (version 6.2.8). Can you help me or give some direction on what is happening here?

I am calling a REST service that returns a JSON error file (response) and HTTP status code 401 (Unauthorized) if no gateway access token is given.

As I said this works in simulator and Apple Watch Series 4 device. I suspect of Bitcode, as in the past versions I had an iOS companion app and disabled bitcode generation, but now we only have the watch app and I cannot disable Bitcode generation.

What did you expect to happen?

Handles the 401 error, calls interceptor, call login again and gracefully logins the user.

What happened instead?

The crash is somewhat like this:

Alamofire Environment

Alamofire version: 5.2.2 Xcode version: 11.7 Swift version: Apple Swift version 5.2.4 (swiftlang-1103.0.32.9 clang-1103.0.32.53) Platform(s) running Alamofire: watchOS 6.2.8 (via TestFlight - bitcode enabled) macOS version running Xcode: macOS Catalina version 10.15.6 (19G2021)

Demo Project

Unfortunately this is a big project for a bank. I do not have yet a demo project because the error only occurs via TestFlight installing on Apple Watch Series 3 (32-bits).
