title: Xamarin build-times extremely slow
body: <p>I have developed several (experimental and prototype) iOS apps using Xamarin and the new Visual Studio for Mac OS and the build-times intermittently take about 5-10 minutes on average. When starting a new project, build-times are fine. After a few changes in the source code while working on my apps (no specific changes). For no reason, build times start increasing to 5-10 minutes. I've tried all possible build-options (linking, no linking, SDK versions, new consigning certificate, etc..).</p>
  
  <p>Upon investigation with the Activities-app (Mac OS, Sierra) i find that the "codesign" process is taking up 110% CPU and runs for as long as the build takes to complete.</p>
  
  <p>Does anyone have any experience with this problem?</p>
