Sounds like you perhaps made the mistake of using the same Apple ID for more than just your owned Developer Program Account - the backend is thus confused and unable to otherwise bifurcate your login. Best way forward is to houseclean each use case, being sure to employ strictly unique Apple IDs as required. If you only use one Apple ID, one account, and you are not on any teams/other accounts, and/or have not used that Apple ID with Xcode's free provisioning in the past, you may need to contact support directly and ask for help clearing the knots. Good luck.

to see "Live Preview"When I use Apples SF symbols See: https://developer.apple.com/design/human-interface-guidelines/sf-symbols/overview/ IMPORTANT All SF Symbols shall be considered to be system-provided images as defined in the Xcode and Apple SDKs license agreements and are subject to the terms and conditions set forth therein. You may not use SF Symbols — or glyphs that are substantially or confusingly similar — in your app icons, logos, or any other trademark-related use. Apple reserves the right to review and, in its sole discretion, require modification or discontinuance of use of any Symbol used in violation of the foregoing restrictions, and you agree to promptly comply with any such request. Devs can only use SF Font/Symbols (don't conflate the two, BTW) when doing UI mockups - not sure a 'live preview' qualifies, perhaps more like a static design, say in Adobe or on a bar napkin...

As of April 2020, it appears yes. See https://ww w.theverge.com/2020/3/23/21191471/apple-app-store-20-new-countries-2020-expansion-developers

When I open the documentation I'm looking at Apple's docs here: https://developer.apple.com/documentation/swift ...but I don't see the icons/columns you're seeing - do you have a link that demos your example, thanks.

Not all point releases are supported via the Simulator in all examples. It's not recommended to manually install components such as this, so... Note the max I see via Xcode 12 is 13.5 as well. If it is critical that you test against 13.7 proper, and you don't wish to side-saddle Xcode 11.7. you may need to find a device that is still on it. Good luck.

Such requests are best put to support directly - use the 'Contact Us' link below, selecting 'account management' as the topic. Good luck.

Log back into App Store Connect and there should be a reminder with a link you can use to proceed. Or, use the Accounts link above and visit the Member Center to do something similar. 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.

Duplicate of what? iOS HIGs says this about the icon: - https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/app-icon/ "Use words only when they’re essential or part of a logo. An app’s name appears below its icon on the Home screen. Don’t include nonessential words that repeat the name or tell people what to do with your app, like "Watch" or "Play." If your design includes any text, emphasize words that relate to the actual content your app offers."

If the name is already in use, the dev is obligated to use another, unique name. If you use their name by simply adding characters to it, expect push-back during review...it could be viewed as an attempt to piggy-back on another app's popularity as a copy-cat, etc. See the ASRGs: 2.3.7 Choose - https://developer.apple.com/app-store/review/guidelines/#accurate-metadata a unique app name, assign keywords that accurately describe your app, and don’t try to pack any of your metadata with trademarked terms, popular app names, pricing information, or other irrelevant phrases just to game the system. App names must be limited to 30 characters and should not include prices, terms, or descriptions that are not the name of the app. App subtitles are a great way to provide additional context for your app; they must follow our standard metadata rules and should not include inappropriate content, reference other apps, or make unverifiable product claims. Apple may modify inappropriate keywords at any time or take other appropriate steps to prevent abuse. If you think you have the rights to a name that is already in use, App Store Support says this about that: App Name Issues If you believe that an app is preventing you from using the app name that you have rights to use, you can submit a claim at the following link. Where appropriate, Apple Legal will forward your contact information and claim to the developer of the blocking app so that they can contact you directly.

Using release, non-beta, Xcode 12.x? What version Xcode was that storyboard originally created with? What happens if you create a new project and then select/rt. click a .storyboard file...do you see all options then? Did you use the Product menu to clean build folder? Did Xcode ask to fix anything in the legacy project?

This isn't the place to have that conversation. Use the 'contact us' link below to make direct contact w/support. Good luck.

Yes, they need to purchase their own Developer Enterprise Program Account (best approach), and no, not legal to share/resell your account.
