How to change architecture of .ipa or .app from arm64 to i386 without source code

Question

I'm writing mobile autotests using C#, Xamarin 6.1.3, iOS 10.2, iPhone 6s Plus, Xcode 8.2, OS X El Capitan 10.11.6. I'm trying to launch tests on simulator using the following command:

IApp iApp = ConfigureApp.iOS.AppBundle(path_to_app/Application.app).StartApp();

I've got the following error:

Calabash.XDB.Core.Exceptions.DeviceAgentException : Failed to install app /Volumes/Win7 Ultim/Framework/new2/Payload/Atom.app

ExitCode: 5

    -a,--app-bundle <path/to/app-bundle.app>    Path .app bundle (for .ipas, unzip and look inside of 'Payload')
    -c,--codesign-identity  <codesign-identity> [OPTIONAL]  Identity used to codesign app bundle [device only]  DEFAULT=
    -d,--device-id  <device-identifier> iOS Simulator GUIDs
    -u,--update-app <true-or-false> [OPTIONAL]  When true, will reinstall the app if the device contains an older version than the bundle specified DEFAULT=1
install

Ios simulator supports only i386 architecture, as I know it cannot be changed. Is it possible to change architecture of application, if I don't have source code, just .ipa and .app files?

Answer 1

It is not possible to change the supported architecture of an .ipa or an .app without the source code.
