Can we delete User properties from Firebase Analytics?

Firebase Analytics has a 'User properties', when we created one, we have 2 fields: name and description. When this property is created, I just have one option, which is edit.

This edit option only gives permission to change the description but not to change the user property name.

Is it possible to delete this user property?

Yes, I am also looking for this answer. There only Edit Option once the property is saved - Adarsh Madrecha
This is like some kind of a joke. I really don't understand why Firebase does not add "remove" option? - Ugurcan Yildirim

Since 2016:

No, not yet.

The official statement is: at the moment, your only options are to create a new project or to wait until we add the ability to delete slots. No ETA on that yet.

2021 Update:

  • The feature is now called: Custom Definitions
  • You cannot delete a custom definition
  • You can archive a custom definition

It seems that an archive option has been recently added, it is also mentioned in the docs.

There's a workaround. You can reset current analytics for the user like this. 

FirebaseApp.configure()

Analytics.setUserID("tt")

// Register properties test1, test2,…test26 (the 26 will fail)
for i in (1...26) {
    Analytics.setUserProperty("test", forName: "test\(i)")
}

Analytics.logEvent("bang", parameters: [:])

InstanceID.instanceID().deleteID { (error) in
    InstanceID.instanceID().getID(handler: { (token, err) in
        Analytics.resetAnalyticsData()

        Analytics.setUserID("tt")

        // Now you can set new 25 properties
        for i in (26...30) {
            Analytics.setUserProperty("test", forName: "test\(i)")
        }

        Analytics.logEvent("bang", parameters: [:])
    })
}

This is handy in case you export events to BigQuery for example.
