Hi I am facing the same issue , I am getting entitlement missing error :
I Added the entitlement to our development provisioning profile
Updated project entitlements to include the apple pay provisioning key with value "com.apple.developer.payment-pass-provisioning " = true
Added Apple Wallet capabilities to the target (not sure if this is needed?)
Created a PKAddPaymentPassRequestConfiguration with some dummy data.
Passed the above configuration to the init for PKAddPaymentPassViewController
but PKAddPaymentPassViewController Is coming nil . Nd missing entitlement error is coming .
I already taken access of this API from Apple
