Since I'm using Xcode 10.0, the amount of tasks which Xcode is building increases every time when I build the project. To reset the amount of tasks I have to clear the project. Can anyone else retrace this issue? The main problem is, that the build time increases with the amount of tasks.
EDIT
Same behavior in Xcode Version 10.1 (10B61)
Xcode 10 introduced a new build system, and it's not without bugs. I was able to reproduce the ever-increasing task count the same way you did. That's a lousy bug! release_notes To fix it search "User Header search paths" in build setting, and set it as NO
