I am trying to test native iOS app using Appium v1.13.0.
When I execute the tests using iOS Simulator lunched by Xcode 10.2, I get the following error from the Appium server.

It seems that your application has been built for iPhoneOS platform only, you will not be able to run it in the Simulator as the simulator assumes different architecture (x86) while real iOS devices run on ARM
You need to execute xcodebuild command and specify iOS Simulator platform as the output target like:
xcodebuild build -workspace "*****.xcworkspace" -scheme "*****" -destination "platform=iOS Simulator,name=iPhone SE" -configuration Release
If you don't have access to the application sources - unfortunately you will be only able to test it using real iOS devices, check out Appium XCUITest Driver Real Device Setup article for the required steps (by the way, the processes of generating/managing provisioning profiles and Simulators/devices are much easier with the Appium Studio)
