The Simulator does not have a camera! Only real device have cameras. Your code may well be fine. Try running it on a real iPhone or iPad, and see if it works. Note: Your code checks "isSourceTypeAvailable(camera)", but you don't take any action if the sourceType is not available. If you (for example) logged an error message to the console, then you would have noticed that your app was not detecting a camera.

Thanks Quinn, that's interesting, but now the plot thickens... I can directly enter this url (and it works as a link): https://kirkville.com/intego-mac-podcast-episode-236-install-macos-monterey-on-a-15-year-old-mac/ ...but if I try to add it as a "link", I get the errors: "Please fix the following URL related errors:" "This domain is not a permitted domain on this forums."

Kirk McElhearn talks about Installing macOS Monterey on a 15-Year Old Mac... I don't know how realistic this is, but it might be worth a look? https://kirkville.com/intego-mac-podcast-episode-236-install-macos-monterey-on-a-15-year-old-mac/

That's interesting, @Claude31... ...and now I can also post directly the URL: https://developer.apple.com/forums/thread/698055 It wasn't working before, but it works now! Perhaps a temporary forum glitch (maybe related to their ongoing attempts to fight spam posters).

You probably need around 60Gb of free space, to perform the installation. See this comment from @Claude31

Hmm... If I just type the URL, that is rejected. But if I type: [Example Link](https://developer.apple.com/forums/thread/698055) Like this: Example Link ...that seems to work!

is there a way to down grade iPhone version Downgrading from 15.4.1 is not supported.

Wait you saying i gotta need to buy a new Mac for this? No, I'm just explaining the software requirements, to develop for iOS 15.4. You have not said what Mac you have.... If it supports Monterey, then you are fine. If not, then you have a decision to make.

From the Xcode 13.3.1 Release Notes: Xcode 13.3.1 includes SDKs for iOS 15.4... ...requires a Mac running macOS Monterey 12 or later. So: If you want to support iOS 15.4 You need Xcode 13.3.1 Which needs macOS Monterey

You could consider unlisted app distribution. The app is on the App Store (with the benefits of easy updating), but is only discoverable using a direct link (not by browsing the App Store). See: https://developer.apple.com/support/unlisted-app-distribution/

Update to the latest version of Xcode (13.3.1)

From App Store Connect, it sounds like you must have set your app's "Version Release" to "Manually release this version". Your app has now been approved, and you need to release it manually. No further approval or action is needed, from Apple. See https://help.apple.com/app-store-connect/#/devabbb787a6

Try this: let imageview = UIImageView(image: UIImage(named: "robin")!)

It's probably a bad time to buy a MacBook Air, or 13" MacBook Pro... updates are expected soon. See https://buyersguide.macrumors.com/#MacBook_Air

There are suggestions that Xcode could benefit from more than 8Gb, and you emphasise multitasking... The other thing to consider is that this may be a bad time to buy the current M1 MacBook Air, as an update is expected soon. See: https://buyersguide.macrumors.com/#MacBook_Air On the other hand (if you want "cheap"), refurbished MacBook Airs are available from Apple (here in the UK), and this could be an excellent buy (I'm still using my refurbished 2015 MacBook Air).
