        I have a strange behavior for a few days. Every debug start in an iOS project (macOS projects start up fast) that I'm working on (even in a blank new project), lasts between one minute (on a USB connection) and over two minutes (on a Wi-Fi) connection. That's so annoying! I use Xcode 11.2.1 and Xcode 11.3 Beta, the same result on both. The host system is macOS 10.15.1 on a Macbook Pro Retina 15 inch (late 2012). The app will always hang in the launch screen until it finally launches. During startup over a WiFi connection, a process called "libd-rpc-server" sends over 25 MB to the iOS device over the WiFi network, even on a completely empty sample project! I have never had that problem before! Please help!

          How much ram in your MBPR?

           

          What size SSD and how much free space?

              8 GB RAM, SSD is 256 GB. More than 100 GB free. Im not running any other software on that machine besides Xcode and Android Studio. It is purely for cross plattform development.

                  8 GB ram is -not- your friend. Max that out, 16GB at least, and consider a larger, faster, SSD.

                  Sorry for the semantics, but it's not about software is running...it's about all the work going on as a result of what's running.

                    Thanks KMT!

                     

                    I do not believe in a hardware related problem. Why?

                    • 1. "System Activity" is telling me: not even 50% of the 8 GB RAM is used during the process
                    • 2. SSD is only 50% filled and fast (Samsung 860 Evo)
                    • 3. The app hangs after building and installing processes are done, so all the heavy CPU load is already done at that time
                    • 4. The problem started only a few weeks ago, before that, it simply didn't exist on the exact same machine

                     

                    All this is telling me: it must be software related.
