[REQUIRED] Step 1: Describe your environment

• Xcode version: 13.3.1
• Firebase SDK version: 8.15.0
• Installation method: Swift Package Manager
• Firebase Component: AppCheck, Firestore, Messaging, Storage
• Target platform(s): iOS

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

After updating to the latest Firebase SDK version, Xcode shows 392 gRPC-Core issues when compiling.
gRPC is on version 1.44.0-grpc
No prior issues, only appeared after the update. Cleaning the build folder did not help.

Xcode states:
Value conversion issue - Implicit conversion loses integer precision: 'uint64_t' (aka 'unsigned long long') to 'uint32_t' (aka 'unsigned int')

Relevant Code:

UPB_INLINE uint64_t _upb_be_swap64(uint64_t val) {
  if (_upb_isle()) {
    return val;
  } else {
    return ((uint64_t)_upb_be_swap32(val) << 32) | _upb_be_swap32(val >> 32);
  }
}
