title: Strange Errors on Archive Validation
body: <p>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 <em>not</em> 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...</p>
  
  <p>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:</p>

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

  <p>Following the suggestions in <a href="https://stackoverflow.com/a/39475232/3799856">this answer</a>, I find that every single one of my compiled assets read as sRGB, <em>not</em> 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?</p>
  
  <p>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.</p>
  
  <p>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 <a href="https://stackoverflow.com/questions/39193705/">dead StackOverflow question</a>. Really wish the author hadn't removed it... Wonder if he found his answer?</p>
  
  <p>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.</p>
  
  <p>Cheers!</p>
