Reply to Xcode simulators not appearing on project list

If you have quite a lot of simulators and they're all set to show automatically, some will be 'lost'. I think you just need to set Show run destination to Always for the ones you always want to see, and they should then always be displayed.

iMessage extension not showing

Hi all,I'm developing an app with an iMessage extension. I'm able to test the extension running it directly on a simulator or a phisical device.But when I do Archive (to send a demo version to the customer) and I install the exported IPA on my device, the iMessage extension is not showing on the iMessage app.When I create the IPA exporting the archive the extension is correctly present in the binary list, with its provisioning profile.Am I missing something?Thanks.

Reply to iOS 14 iPhone folders disappearing

i am having the same issue. The folder vanished as well as all the icons for the app. They dont show up anywhere. however if i do the search bar and type in the name of the app... it appears in the search and i can run it. The apps also show up in the appropriate areas of the setup interface such as under notifications Obviously the app is still loaded and still runs. But only from the find/search feature first

Reply to [iOS simulator] : nw_connection_send getting error "nw_write_request_report [C1] Send failed with error "Permission denied""

but running in iOS simulator, it did't show to ask the local network permission. Right, the simulator will not show the local network permission prompt, as it is technically running on the network stack from the macOS machine. As to what is happening in your title, you mentioned that you were doing local network discovery. Can you share any more code or information on what you are doing here?

Reply to structure of a Swift app - main.swift vs. AppDelegate

I created a sample project, and removed the line `@UIApplicationMain` in AppDelegate.swift,and then added main.swift . The app runs fine without any problems.If This didn‘t work for you, there may be something wrong in your main.swift. Please show your main.swift.And please describe didn't work more precisely.- It does not compile?- Causes some runtime error?- Or runs without error, but shows an unexpected odd behavior?

Reply to Create ML in XCode 11 Beta?

Yes, you need to be running the macOS Catalina beta as well. Then it will show up among the developer tools.I'm running Catalina from an external drive, and Xcode from my built-in disk… had to give myself permissions for that.

Reply to Download link for 10.12.1 Beta (16B2553a) ??

You can't run the packages individually in sierra, but you can run them from another partition with el capitan - as per instructions in the other thread.This method does not require it to show up in the mac app store.

How to make window not show up

Hello all,I am trying to build an app that sits up in the menu bar. Unforunately, I can't get the main window to not show up when I run the app. I made the dock icon go away by editing it in info.plist, but when I try to delete the window in Main.storyboard, I can't find an option. I only want the app to show up in the menu bar, which is why I want to get rid of the window.

xcresulttool for Xcode 16 does not show warnings

Running xcrun xcresulttool get build-results --path ResultFile does not always show the warnings that the build emitted, If I run the legacy command, xcrun xcresulttool get --legacy --path ResultFile against the same file, there are (numerous) warnings, where the non-legacy call above shows no warnings.

Reply to Where is 15A262c? Do not see it!!

It's strange, my App Store is showing Public Beta 5 available, when what I am running now is Developer beta 6. I am a developer, and got the last release from the direct download links posted in the forums here. My version number I am running now is 15A244d - Developer Beta 6. I wonder why my App Store is only showing Public Beta 5, and I cannot download Dev Beta 7...my developer code shows it is already redeemed, per the original Dev Beta 1.

If you have a look at Activity Monitor does that show SourceKitService hogging the CPU and are your fans running flat out?

Watch OS4 always show stopwatch

Anytime the stopwatch is running the wake screen is the stopwatch. I use the utility watch face so I can see multiple things at once (stopwatch, timer, etc) and now every single time I glance at my watch it shows just the stopwatch app and nothing else anytime the stopwatch is running (which is always for me). It’s rendering the utility watch face useless.
