Uno platform mobile app does not work on iPhones

[Sankar-san]

We created the Uno platform project using the visual studio tool. Uno mobile app runs on web browsers, simulators and android devices but it does not work on iphone devices.

Error details

• ApplicationVerificationFailed: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.nErsMe/extracted/sample.Mobile.app : 0xe800801c (No code signature found.)

• error MT1006: Could not install the application '/Users/developer/Workspace/sankar/unoPlatform/sample/sample.Mobile/bin/Release/net7.0-ios/iossimulator-x64/sample.Mobile.app' on the device 'iPhone (2)': AMDeviceSecureInstallApplicationBundle returned: 0xe800801c.

• AMDeviceSecureInstallApplicationBundle returned: 0xe800801c

• Application could not be uploaded to the device.

Could you please help me figure out how to resolve this build issue?

This is strange. At first it looks like some issue with code signing.

But your 2nd screenshot shows a Release build for devices, while your 1st screen shot mention the app being built for iossimulator-x64. That of course cannot work.

Can you attach a .binlog of the build ?
Or attach a zipped version of your project ?

Build log file screens.
I changed the build options Release to Release X64.

The attached build is not a .binlog so it does not have as much information. It's also the log of a successful build - so it does not show anything wrong.

A x64 release build seems weird - since there's no iPhone with an intel x64 processor. However your screenshot still mention simulator-x64 while the UI hints you are targeting a physical device (and not a simulator).

Could you please tell me about references for ios app step by step configuration guidance?

This does not look like the previous issues you mentioned. You need to provide either a self contained test case (so we can reproduce the issue) and/or the binary logs so we can investigate any problem.
