ios - What is the use of entitlements.plist file? -

I have a few questions about the entitlement file.

1) What is the use of entitlement file

2) What if I will not add it?

3) What is the difference between myApp.entitlements and entitlements.plist?

1. The entitlement file defines some of your app's capabilities Generally, when you enable the capability for your app, then the file is automatically generated by the exode.
2. If you enable some capabilities, you only need the file, e.g. Health Kit Integration If you want to use these features, you have to add it. Otherwise, Apple will reject your app.
3. You may want to name the file. You can rename it until the build settings point to the correct filename for it.
