Hi Ed, Please refer to FB15634383 for the report. On the suggestion, while I thought it was unfeasible in my use case, I did give it a try. Unfortunately, that too, did not work. I will elaborate further in a comment with a sample project in the same FB report. Thank you.

Thanks for your reply! I have not tried it yet, but it is certainly more assuring to me to hear that the rule doesn't cover the entire Network framework. Now I can try without the thought that I would definitely be wasting time on something that might not work at all - since at least there's a chance that it might work!

What about watchOS? UIGraphicsBeginImageContextWithOptions is available in watchOS, but UIGraphicsImageRenderer was never ever available for watchOS, resulting in basically no replacements for watchOS.
