Well, that’s a bummer. So basically what you’re saying is: DTS no longer offers any real, first-hand support and has pretty much shut down its service altogether? Sure, moving support to forums sounds like a good idea — more people, more visibility, more shared knowledge. Theoretically. But that only works if you actually bother to answer questions there. Ignoring both emails and forum posts equally? Brilliant strategy. That really helps… no one. Excellent job, Apple. Really raising the bar.

Thanks for your response. Meanwhile I have received a response to my DTS ticket. However, it was not particular helpful. I have posted the problem here on the forum as well: https://developer.apple.com/forums/thread/781318 Any help is very much appreciated.

Thanks for the hint. However this fails with: Failed to build the scheme “MyAppScheme”

I have submitted the feedback including the diagnostics report as advised: FB15429176
