what is SPI Check while uploading iOS?

Question

while uploading the app from xcode 13.x it stuck to

"Performing SPI Check.."

any idea what is this about?, added a pic for reference.

Answer 1

Service Provider Interface most likely, and I'd be guessing they are checking for usage of private APIs https://en.wikipedia.org/wiki/Service_provider_interface

Answer 2

I also faced the same problem, but it worked after retrying the upload process.

For anyone, if the issue persists try restarting the Mac or try more suggestions from this Thread
