Hi, thank you for the hint. But this is not the case. The problem is that I create a column with an expression using start time and end time. Something like this: <start-pattern> <time>?starttime</time> <message>...</message> </start-pattern> <end-pattern> <time>?endtime</time> </end-pattern> <column> <mnemonic>milliseconds</mnemonic> <title>msecs</title> <type>fixed-decimal</type> <expression>(/ (- ?endtime ?starttime) 1000000)</expression> </column> This worked with Xcode 13.2 and earlier and does not work with Xcode 13.3 anymore.

As mentioned iOS 11.4 is installed but does not appear in the selection box:

same here. Had to try 10 times or so until it worked. Seems to be an unreliable connection :-(
