Crash when launching applications on iPhone 6 in debug mode

From @manijak on December 6, 2015 21:38

I just updated my iPhone 6 to iOS 9.1, and I am having issues in running the app from device.

If I use tns deploy ios or tns run ios or tns debug ios I get the app deployed successfully message, but the app crashes as soon as it starts. No error or exception in the terminal…

If I deploy the app directly from xcode 7.1.1, everything runs fine. App does not crash, no errors.

I managed to find the crashlog on the device, here is the exception part, but it doesn’t say much to me.

Ok, CLI sets ARCHS to armv7 and arm64 for both debug and release builds, but in debug build the Build Active Architecture Only is set to Yes. ios-runtime have applied a fix, which allows iPhone 6 to run armv7 architecture - it will be included in 1.6.0 release. Anyway CLI should check attached devices type and build for correct architectures. At the moment, the only workaround is to use release build of the application (pass --release flag).

Unfortunately I don’t believe the CLI has the same idea of active device as Xcode. The CLI could generally poll for a connected device before doing a build and constraining to architecture of the device the app will run on, but I think this is beyond the scope of the iOS runtime itself. Perhaps we can move this to the CLI repository, having narrowed down the source of the problem?
