iOS development IPA cannot find module for architecture arm64 - ios

Question

I'm on the alpa testing stage of the application that I'm building. It's pure js, no alloy.
Everything runs fine when ran from the studio and I've used the IPA build by it to send it out to 2 other testers (iPhone 5c and 6 Plus). The 5c runs fine, however the 6 Plus keeps reporting that it get's the following error:
Couldn't find module: ui/common/MasterView for architecture: x86_64
That was kind of odd, given that the simulators and my physical devices (4S with 9.1 and 6 with 8.3) worked fined.
I was finally able to reproduce the issue by building for the simulator from the CLI with the following command. I also ran with debug level and saw the line below.
appc ti build --platform ios --sdk 5.1.1.GA --target simulator -V "MyDeveloperCertificate" -P DevelopmentiOSProvisioningProfile
[DEBUG] Loading: /Users/lmtzusr/Library/Developer/CoreSimulator/Devices/C5FDC6E8-16B3-400A-BE02-7395B73C5060/data/Containers/Bundle/Application/E20F949C-712E-4DCC-A6F1-77537C3CC85C/MyNew.app/ui/common/MasterView.js, Resource: ui/common/MasterView_js
Here is the output of the build command and also the output of info

Answer 1

The "flow" is so: app.js -> ui/handheld/ios/ApplicationWindow.js -> my stuff
If I move my ApplicationWindow.js into the expected location and change the name it works fine. Is there an undocumented feature that requires to have files named in specific ways (besides app.js).
Hopefully is just something odd and doesn't make a difference if I change my application in the way that it works (renaming the file and moving it).
