Recently, we have witnessed problems in installing our native Xamarin mobile applications on older Apple devices. Although it appeared that the problem may be in the operating system IOS 9, it turned out that the operation system does not matter. The error was caused by 32b processors that used to be installed in older iPhones. It is because Xamarin changed the default settings for build applications that were not compatible with these devices.

The fix is fairly simple, just set the supported architectures in the project to: ARMv7 + ARMv7s + ARM64 and the problem will be solved.
