so anyway Apple engineers, how about this Interesting comments, however, as forum posts are not bug reports (and you're mainly talking to other devs here), feel free to make enhancement requests against the tools via the feedback/bug link below, being sure to add your report #s to your thread for ref., thanks and good luck.

I don't think anything has changed since this previous discussion: https://developer.apple.com/forums/thread/31122 Your question, tho, could benefit from more info...are you asking about iOS apps for the store, or w/an Enterprise account, or...?

If this tool (menus are changed, but this isn't new w/12.x) is TMI, uncheck Minimap (or press ^⇧⌘M) via the Editor menu. I would assume it was added a while back because not all devs use the tools the same way...some are more visually adept, some just want text controls they can read and process with the other side of their brains, some need less clutter, some want all the info they can get.

I suspect you've run across bugs in 12.x specific to device support - file some, add your report #s here for ref. and good luck.

User-centric questions/complaints for release OSs are perhaps better suited for Apple's public community forums rather than risk off-topic here in devForums, thanks and good luck.

this one issue is driving me crazy ~ tried investigating  You might try burning a support ticket w/DTS via the Member Center to see if they can shed light - they will need a buildable project that demos the issue... Good luck.

Not sure why you've chosen this particular exercise, but more than likely what you're witnessing is simply an artifact of the buffered IU updates being throttled while the system attempts to realize true state. If this is some sort of durability spec on a given project, I'd log the results and see about negotiating something more representative of which the IDE may be better suited. As it is, you seem to just be intent on watching it's eyes roll back while you thrash on it ;) Goal met, yay... If this is a hard requirement, feel free to make an enhancement request against the tools via the feedback/bug link below, being sure to add your request #s to your thread for ref., thanks and good luck.

Be patient, and next time, get the app in the store first. Never ever assume an approval. Good luck.

) devForums is not the place to make these types of requests ) read your dev agreement, there are no refunds ) feel free to contact support directly via the 'contact us' link below, but hey...#2, so you might want to keep your expectations low. Good luck.

What version Xcode and which iOS version are you working with? When do you see this error...what you were doing, what you expected, how those differed...

I am assuming That would be a correct assumption.

Seen this previous thread? https://developer.apple.com/forums/thread/126928

Assuming you're using Xcode 12.x, the problem for you is that those tutorials are for older versions. Xcode 12 doesn't have that template. Doesn't mean it can't build the kinds of apps those tutorials promote, just that those 3rd party YT videos depict outdated processes (we could tell you how to make a single view app, but that might not mesh with that tutorial, so not much point...you'be all dressed up w/no where to go). Recommend you use the links above and let Apple lead you instead, while you wait for 3rd party videos/tutorials to catch up. Just remember to always confirm whatever resource you grab is compatible with your tools. Good luck.

If you mean Python - see: https://developer.apple.com/forums/thread/128049 Otherwise, contact the authors of any 3rd party tool/SDK/API and ask them for support with their products. Good luck.

Apple Music API is now a part of MusicKit and can be used with iOS apps, Android apps, and websites. To communicate with the Apple Music service, you’ll need to create a MusicKit identifier and private key to sign your developer tokens using Certificates, Identifiers & Profiles, via the Member Center, where access to C,I&P requires a paid Apple Developer Program account.
