I tried yesterday turn off all network on my device and turn off Wi-Fi and Bluetooth on the MacBook but it did not help to speedup debugger.

I attempted to examine the log of lldb by including the following command. log enable -f /tmp/lldb.log lldb all As a result, it generates over 800MB of logs consisting of 4.5 million lines. During the launch of the app, the log gets filled with approximately 3 million lines similar to the ones mentioned above, as well as numerous others. demangle swift: $s10PostingKit29Component5TableViewCo... -> "partial apply forwarder for implicit closure #1 () -> ..." (not cached)

But with dSYM time of build is long as long resolving symbols without dSYM!

@asmustofa sorry, I tested solution with device only.

Cleaning DD does not help. Also I tried to build the old version (6 months ago) of our Project - same errors and problems.

So, in order to fix the duration of the first breakpoint, I must set the DEBUG_INFORMATION_FORMAT to dwarf-with-dsym. However, this option makes the build time longer. A lose-win situation. Not ideal.

Nice hack! It works. Thank you for that! We have more than 470 modules, so we need to set this option multiple times to have a working po in runtime, if we encounter a bug that "jumps" from one module to another.
