Hello, I downloaded the Swift Playground application on my macbook, I launch any lesson, but no animation is played in the right window, just the blue screen is blank. Instead, an error appears There was a problem running this page. Check your code for problems. If you are stuck, start over to delete all of you changes on this page and try again. https://drive.google.com/open?id=1OPdiEkgMTWTwhW3g_bf-SdWE0MqTZ0bs

Good afternoon, I have encountered a problem that I do not have the opportunity to select a build for external testing, but I can test the application through internal testing. How can we make testFlight let me choose the build I currently have?

Hi all! I got the application approved for publication in the AppStore, after which I got an error that some agreements are outdated and need to be updated by going to the business tab, all my agreements have the status “Active” and I can’t change anything. How should I deal with such a situation? There is no “Submit application to AppStore” button. The app has been in this status for a week now and nothing is happening.
