Error MT1108: Could not find developer tools for this 10.1.1 (14B100) device

SABUJAMESSABUJAMES USMember

Hi,

I am trying to do the profiling of my application in iphone device. It gives me the error "error MT1108: Could not find developer tools for this 10.1.1 (14B100) device. Please ensure you are using a compatible Xcode version and then connect this device to Xcode to install the development support files.".

Note : The debugging of the application works** fine using the same phone. Problem is only when I do the profiling. The version details of the developing environment are below.

IPhone OS Version : 10.1.1(14B100)

Mac PC OS version : 10.11.6 (15G31)
Xamarin Studio Version : 6.1.1 (Build 17)
Xamarin Profiler Version : 0.38.0-0
XCode version: 8.1 (8B62)

Please help me to solve this.

Thanks
Sabu

    Hi,

    Is this message thrown by XS?? if it is, could you share the xamarin Profiler log[0] please?

    Hi,, hmmm maybe you will need to update xamarin packages (according to this october release note )

    Check the version and let us know

  • SABUJAMESSABUJAMES USMember

    Sorry, The log file attached was for simulator. Please find the log file for the device.

    I am using the Xamarin.iOS package latest version. 10.2. - released on 28th Oct 2016.

    Hi,

    Same error: error occured on run com.PHG.lntts error MT1108: Could not find developer tools for this 10.1.1 (14B100) device. Please ensure you are using a compatible Xcode version and then connect this device to Xcode to install the development support files. It's weird, if you are able to run an iOS app from XS you should be able to profile that app.

    Had the same error, but when I deleted the folders in bin & obj and it worked. (Worked for me, and I don't say that this is the correct solution)

    After adding an iOS11.1 iPhone, I started getting this often:

    Connected to: J’s iPhone
    error MT1108: Could not find developer tools for this 11.1 (15B93) device. Please ensure you are using a compatible Xcode version and then connect this device to Xcode to install the development support files.

    My workaround is to clean the project (or delete the obj and bin folders) and then after the app is installed I manually launch the app on the device which then connects the debugger.

    Can confirm that launching manually allows the debugger to connect. Thanks @JannieTheunissen
    Works around the following error message. (Adding so Googlers can find it.)
