DTK, Xcode 12 beta, no simulators

I am trying to run a simulator on the DTK without success. They do not appear. I have downloaded the runtime. Running "xcrun simctl list runtimes" gives the following: == Runtimes == iOS 13.5 (13.5 - 17F61) - com.apple.CoreSimulator.SimRuntime.iOS-13-5 (unavailable, failed to open liblaunchsim.dylib) iOS 14.0 (14.0 - 18A5301v) - com.apple.CoreSimulator.SimRuntime.iOS-14-0 (unavailable, failed to open liblaunchsim.dylib) So why can't "liblaunch_sim.dylib" be launched?

Query regarding Xcode

In my system Xcode application is not working. I mean when I am clicking on Xcode icon it is not opening (it only pop up)or I can say that it is not responding. While when I am opening my old file of Xcode then that file is working fine. But I am unable to create new files. I am facing this problem since last 5 month. I am rewriting my codes on same old file again and again. Even I uninstalled the Xcode then install it again in the hope that it will run properly but unfortunately situation is as I have mention earlier above. Kindly resolve my issue.

Xcode and Gamemaker Studio 2

Hi There, I am working in Xcode for weeks. Trying to get through the difficulties and issues. Maybe somebody could help me here!?' I created a platform game over Gamemaker Studio 2. I created and programmed it on my PC (Windows 10). Then I recently bought a MacBook Pro and installed Gamemaker Studio 2 thereon. I saved the .yyp-project (GMS2) with all links on a stick and put it on my macBook Pro. I opened the project with GMS2 (mac version) and tested it - worked fine! Then... I´ve got the apple developer certificates, currently using a wildcard-ID with de.domain.* for testing needs. I´ve chosen an iPad 7th gen. for simulating device, even my macBook Pro. OK! And I made an executable data from GMS2 and Xcode automaticaly opened its screen. There came a lot of issue reports. Many of `em could be easily solved. But there are some further problems I cannot solve... I am an absolute Xcode-novice... but I´d like to learn. Can somebody tell me understandable, how could I fix following issues? An attribute in the provided entity has invalid value. The attribute "name" is invalid: "XC de domain *" No profiles for "de.domain.* were found: Xcode couldn´t find any Mac Catalyst App Development provisioning profiles matching "de.domain.*". MobileCoreServices has been renamed. Use CoreServces instead. Building for Mac Catalyst, but the linked library "liyoyointerpreted.a" was bulit for iOS + iOS Simulator. You may need to restrict the platforms for which this library should be linked in the target editor, or replace it with an XCFramework that supports both platforms. Hope to be helped with these troubles. Best wishes. Archie.
