delete analytics data

To my knowledge, there's no way to delete previously collected analytics data.

No, I don't think you can.

You can only stop sharing your analytics data.

Hello

I have managed to delete most of the gathered analytics data without resetting the device by using Xcode's tool "Devices and Simulators" (a screen shot of the tool is seen in the Fig. 1.).

This is probably rather heavy workaround for most of the typical users as you only need one tiny application from the Xcode to accomplish this. Additionally, consider the following before rushing into the action:

1) you do not gain much from purging of the analytics data (apart from removing some clutter if it bothers you .)

2) this approach might not work all of the time

3) understand that the use developer tools on your device might activate features that are not discussed here. Proceed only if you know what you are doing...

4) and finally, do take backups of your device *before* doing anything, just in case!

What you need is:

1) a MacOS/Mac OS X operating system (in order to run Xcode... Tested on version 10.13.4)

2) Xcode (search from the App Store. Tested on version 9.3)

3) Your device attached to the computer with a USB cable (tested on iPhone 7/iOS version 11.3.1).

Once you have Xcode installed, do the following:

a) Open Xcode, and select menu "Window > Devices and Simulators"; or use the short cut ⇧⌘2 for the same effect

b) If this was the first time you used Xcode together with your device, Xcode might instruct you to unlock your device, and approve something before your device appears to the list of devices

c) Once your device appears to the list, select your device, and click "View Device Logs" (Xcode might download some symbol data from the device before the button is enabled)

d) Select the log files you want to remove (you can select multiple items at once)

e) Right click/secondary click over the items to open a menu which says something like "Delete Logs, Export Logs, Re-Symbolicate Logs"

f) At this step, you may want to export the log files if you think they are important

g) Click "Delete Logs" and follow the instructions given by Xcode application.

The first time I deleted logs using this method, the list shown in Settings > Privacy > Analytics > Analytics Data was reduced to only a few items. Since then, newer logs have been generated, but deleting them by using this method *did not* remove them from the iPhone's list of analytics data. So, it seems that this approach only deletes the old logs (i.e. the logs with smaller version number than is currently in use, but I have not been able to confirm this because there has been no updates).
