We have a test tool our engineers use to launch various versions of our application during development and verification. Each daily build of our application is stored on a server. As well, each push of a change generates a new build of our application that is stored on a server. These are added to a database and the developer application accesses the server via REST to find the desired version to run, retrieves a server path and launches the application. This tool is valuable in finding pushes that introduced regressions. The developer application (Runner) is using the launchApplicationAtURL:options:configuration:error: (deprecated I know) to launch the app. Prior to Catalina, this was working great. However, as of Catalina, this process is taking a VERY long time due to the app needing to be "verified". the app seems to need to be copied to the users machine and verified. It only occurs the first launch, but as most of the time the users are running new push or daily builds, it has made the app useless. With the new remote work environment it is even worse as VPN copy can take forever. I have switched to using NSTask with a shell script to open the executable in the bundle. If I add the developer tool (Runner) to the Developer Tools in Privacy this seems to launch the application without the need for verification. However this just seems wrong. It also provides little feedback to know when the application is up and running, which makes my user experience poor. As well many of the systems we use this tool on for verification do not have Developer Tools installed. They are VMs. Is there a way for me to use the launchApplicationAtURL:options:configuration:error: (or the new openApplicationAtURL:configuration:completionHandler:) to launch these versions of the application without the need for the lengthy verification process? Adding our application to the Developer Tools did not seem to help.

I have an iOS 13 app that I’m hoping to release soon that is written entirely in SwiftUI. If I was starting from scratch today, I’d obviously use the new multi platform template which looks awesome.... But since I’m not starting from scratch, what are the recommendations/best practices for existing apps? Is there a path for migrating existing apps to take advantage of the new app structure (below) when moving to iOS 14? @main struct HelloWorld: App { var body: some Scene { WindowGroup { Text(“Hello, world!”).padding() } } }
