Question

Everything works fine till I build my cordova application with Xcode 7.3.0 but it started crashing only on iOS 10 devices after building the same application with Xcode 8 whenever i'm changing the orientation from Portrait to Landscape where as it still working fine on iOS 9.3.1. In debugger i'm getting following logs:

• iOS 10 iPhone 6

Please help.

Answer 1

I was getting the "invalid capability (0x14) "Unable to insert COPY_SEND" message in the debugger which would prevent the app from launching for about 10 seconds.

I had breakpoints set in files that I had since removed from the project but were still showing up in the Breakpoint navigator (file names in red).

I removed ALL breakpoints and haven't seen the error message since.
