App paths need to be absolute, or relative to the appium server install dir, or a URL to compressed file, or a special app name

I’m using Appium Desktop 1.7.0 and I can’t seem to get the right path. I compiled the iOS app on a simulator, and then I go to the app’s bin/release folder to get the .iOS app but it gives me the error. Then I create the path to go to the actual iPhone simulator’s path to find the app and it still gives me the error.

My JSON
{
“platformName”: “iOS”,
“platformVersion”: “11.4”,
“deviceName”: “iPhone Simulator”,
“automationName”: “XCUITest”,
“app”: “~/Library/Developer/CoreSimulator/Devices/99C9B21A-5D11-47DF-AA60-1CA9F212D1C1/data/Containers/Data/Application/A15D0561-D55F-49E2-8C17-184DC441AEAC/MyApp.IOS”
}`
