delphi seattle, iOS simulator run, can't load devToolsFoundation

Hi.

I'm trying to set up compiling an app for iOS using the iPhone 5 simulator. I am running Delphi 10 Seatle on a Windows 10 machine, and the X-code on a Mac with macOS Sierra 10.12.5. X-code is up to date, version 8.3.2.

I have PA server 8.0.1.52 tested running and connected. I have created an SDK. I have X-Tools running with the simulator.

When I click the run with debug command in the IDE I get the error "Can't load devToolsFoundation"

If I click the run without debug command in the IDE I get the error "Unable to launch process on [ip] using the parameters from the iOS profile. Can't load devToolsFoundation"

The app will compile as windows 32 and 64 bit, and also for Android.

I have no idea where to go from here.

Thanks in advance
