In "Create asset catalogs and sets" - https://help.apple.com/xcode/mac/current/#/dev10510b1f7 - I read this: " Create an iOS or tvOS launch screen image set: Choose App Icons & Launch Images > New [OS] Launch Image from the Add button (+) or from the Editor > Add Assets menu. For an iOS app, you can also change the default launch screen source to an image set. " But neither the Editor -> Add New Asset menu nor the Add button (+) menu contains an "App Icons & Launch Images" item. I can add that I use Xcode 16.1. So again, the Xcode documentation is quite misleading and confusing! My (real) question is if it is possible to give Xcode ONE launch image from which Xcode creates all necessary image sizes automatically? Or do we still need the apps and services that creates a bunch of launch images from ONE image?

In several places on https://developer.apple.com/documentation/xcode/configuring-your-app-icon I read: "In the Project navigator, select an asset catalog." But my Project Navigator does NOT contain any "asset catalog". So it's impossible to follow the instructions of the documentation, and thus specify a new app icon (set). I can add that I use Xcode 16.1 on MacOS 15.0.1 Sequoia. I have added a screen shot to document what I am saying. I have also reported this error in https://feedbackassistant.apple.com/feedback/15738182

Hi! I am trying to test an app developed in Xcode 16.1 on an iPhone 7 running iOS 15.8.3. My MacOS is 15.0.1 (Sequoia). But I am getting "iPhone is busy" no matter what I do. And yes - Finder can see the iPhone 7 and show information about it. I have followed a lot of advice that is supposed to solve this, for instance here: https://forums.developer.apple.com/forums/thread/692230 And here: https://stackoverflow.com/questions/46316373/fixing-xcode-9-issue-iphone-is-busy-preparing-debugger-support-for-iphone/48238062 But nothing works. Actually it's getting worse... At one point it said "100% complete", although it was still "busy". But now I don't even get to the "100% complete" message... (After 30 minutes.) So my conclusion is that it's impossible to use an iPhone 7 running iOS 15.8.3 to test an app developed in Xcode 16.1 on MacOS 15.0.1. Am I right? In that case: Which iPhone models and iOS versions can be used instead?

I just did a fresh install of MacOS Sequoia 15.0.1, then I installed Xcode 16. Then, in Terminal, I did: xcode-select --install Which created a pop-up window from which I installed the Command Line tools. Later that day I used the command "brew doctor", and got this warning: Warning: Your Command Line Tools are too outdated. Update them from Software Update in System Settings. If that doesn't show you any updates, run: sudo rm -rf /Library/Developer/CommandLineTools sudo xcode-select --install Alternatively, manually download them from: https://developer.apple.com/download/all/. You should download the Command Line Tools for Xcode 16.0. And yes, System Settings -> Software Update showed that Command Line Tools needed to updated. I find this to be very strange behavior of MacOS Sequoia 15.0.1...
