Runtime TypeError getBigUint64 is not a function using Safari 14

Hi @timostamm, I have recently updated to Safari 14 and noticed the following error in my application which appears to be coming from the runtime. https://github.com/timostamm/protobuf-ts/blob/72866167d93aa0471da25dc82475014465a08847/packages/runtime/src/pb-long.ts#L159

Unhandled Promise Rejection: TypeError: O.getBigUint64 is not a function. (In 'O.getBigUint64(0,!0)', 'O.getBigUint64' is undefined)

Surprisingly, I didnt see this error in Safari 13, despite this method apparently not being supported. Im guessing the error was silently ignored?

I did find some discussion on this topic already and it looks like it wouldnt be too bad to write a polyfill using JSBI.

System information

• macOS: 10.15.7
• Safari: Version 14.0 (15610.1.28.1.9, 15610)

Let me know if there is any other information I can provide! Thanks again for putting together this project!

Thank you both for the details! This is fixed in release v1.0.8.

Safari 14 adds the BigInt constructor function, but it does not implement the DataView BigInt methods.

The fixed code if all necessary BigInt features are present.

When running bigint code in Safari, the following error is raised:
