Enable developer mode (required to install an app): https://docs.expo.dev/guides/ios-developer-mode/

You need to sign the app with an ad hoc provisioning profile that includes your device UDID, see Distribute to registered devices (iOS, tvOS, watchOS)

Info.plist

Keys: https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html

Version

	Android	iOS
Public (visible on the store)	`versionName` - A string ("1.0")	`CFBundleShortVersionString` aka version or marketing version
Private	`versionCode` - An int (1)	`CFBundleVersion` aka build number - Can be a single digit (1, 2, 3...) or "1.2.3", or even "1.2.3.540"

Similar to Android's versionCode, the build number also needs to increase, although you can have the same build number for two different versions.

If you upload a build to the App Store with a build number that already exists for that version, you get this error:

ERROR ITMS-90189: "Redundant Binary Upload. You've already uploaded a build with build number '1' for version number '1.0'. Make sure you increment the build string before you upload your app to App Store Connect. Learn more in Xcode Help (http://help.apple.com/xcode/mac/current/#/devba7f53ad4)."

Test push notifications on the simulator

Create a file pushtest.apns:

{
  "Simulator Target Bundle": "<bundle identifier of the app>",
  "aps": {
    "alert": "Push Notifications Test",
    "sound": "default",
    "badge": 1
  }

xcrun simctl push <simulator identifier> <bundle identifier of the app> pushtest.apns"
