    I would like to change the height of the GroupHeaderTemplate to match the content that I put in it. This works in Android. For example, if I have a Grid with a HeightRequest of 70, the GroupHeaderTemplate will be a height of 70 on Android. However, for iOS the height is fixed and will never change no matter how tall or short the content is.

    How can I change the height on iOS?

    Hi Ron,

    You can change the height of the listview group headers through the layout's GroupHeaderLength property. Please, let us know if you have further questions.

    It only works perfectly if (1) the heights of all headers are the same, (2) you can predict what that height is at design time, and (3) it doesn't change.

    On Android, the height of each individual header adjust to the size of its contents.  It needs to be the same on iOS.  There is a bug report on this, but it's pretty old and doesn't appear to have been fixed.  https://feedback.telerik.com/xamarin/1365964-listview-groupitemtemplate-does-not-respect-its-template-contents-in-ios-automatically
