Strange Errors on Archive Validation

Question

I've had an iOS project in fairly stable condition up until Xcode 8's public release. After a bit of confusion with the Migrator, I finally convinced the compiler that I did not want to go Swift 3 yet, and that my code was indeed valid Swift 2.3. Not sure if this at all relates to what the Organizer does in validating my long-awaited archive with some long-overdue fixes for iOS 10, but we'll see...

Anyway, I got Xcode to archive my latest build (which runs fine on my iPhone 5s by the way). I tell Organizer to "Validate..." in preparation for an upload to iTunes Connect. After a good deal of doing its thing, it finally spits this at me:

Been at this for three days now. Application Loader gives me something similar, but not much more helpful:

Following the suggestions in this answer, I find that every single one of my compiled assets read as sRGB, not 16-bit, or P3. Aside: When does an API analysis file get "too large"? I mean, sure I use Apple's APIs a lot, but I can't be alone in that. That's what they're for, right?

I've tried (almost) everything I can think of. I've redone my code signing a dozen different ways, read and recombobulated the build settings wherever I thought could be relevant, and tried every combination of bitcode and symbol inclusion available to me. Just about everything I could come up with short of migrating to Swift 3! Could that really be my solution? It's a rather big jump, and with the time I have, I'd prefer to get this working build out to my users before I'm slammed too hard to shore up the updated codebase.

I can't seem to find anything on "ITunesSoftwareServiceAuthenticationErrorDomain", or this mysterious "error 434". The only reference I've found so far leads to a dead StackOverflow question. Really wish the author hadn't removed it... Wonder if he found his answer?

So my question is as follows: What am I doing wrong to get these errors, and how can I fix them? I'd rather not have to upload without symbols or bitcode, so if that's the workaround, I'd like to know why, so I'm not limiting myself for something dumb.

Cheers!

Answer 1

I had the same problem with Xcode 8.2 while submitting my application:

 ITunesSoftwareServiceAuthenticationErrorDomain error 434. 

Solution: I switched to different network and it worked for me.
