Hi Panos

Thank you for your lengthy descriptive explanation. It’s appreciated. 

Perhaps this should be written in the Release Notes - you know, for clarification. So that a newbie or even an oldie knows what to expect. If the RN says it’s not supported then they/we will be ‘scared off from using it. ‘It’ being either LC or the new OSs/Xcode’s/Eclipses/Whatever’s. Especially as you put so much effort into writing it. 

Still, your fix has been sat on github for 2months held ‘at the mercy’ of waiting for other bugs to be fixed and features added/completed. In 3 or months time Apple will ‘announce’ another major version of iOS MacOS and so on. And, at this rate it will be another 12 months (start your stopwatch) before ‘support’ is added. And so the cycle continues. It could have been sorted and fed out 6mths ago without a doubt. 

It has to be remembered that LC is not the only software we have running on our systems, each with their own set of ‘requirements’. So of course we will have need for the latest os and Xcode. And then the need for multiple Xcode and terminal commands to avoid conflicts. So clarity is definitely needed and appreciated. Hopefully by painting a picture of the other side of the fence helps in understanding ‘why’ getting it out of the door quicker is very much needed. 

All the best
