Test iOS App without Developer Account
To test iOS App you need only Apple ID without paid Apple Developer Account, but to test IAPs (In-App Purchases) you need to enroll.
Get Free iOS Developer Account
You just need to sign in with your Apple ID in Xcode 12:
Xcode > Preferences > Accounts > Apple IDs > “+” > Apple ID.

Create Free iOS Certificate
You can create once and further choose every time your “Personal Team”:
Xcode > Targets > (Choose your Target, e.g. for Unity Project: “Unity iPhone” (black Unity icon)) > Signing & Capabilities > All > Team > Select Your Team.
All needed files (iOS free developer certificate and provisioning profile) you will get automatically.

Remove IAP Capability
You need to remove IAP Capability If you see next message:
“Your Development Team does not support the In-App Purchase capability”.
To disable IAP Capability do next: Xcode > Targets > Your Target > Signing & Capabilities > All > In-App Purchase > Remove (cross on the right) & Click “Try Again” Button.

On the other hand, you can remove Unity Ads package in Unity Editor using Unity Package Manager to avoid removing IAP Capability every time in Xcode.
