    It is your own task to set some environment variables to fit your platform, such as PATH, QT_PLUGIN_PATH, QML_IMPORT_PATH, and QML2_IMPORT_PATH. aqtinstall will never do it for you, in order not to break the installation of multiple versions.
 
+.. warning::
+   If you are using aqtinstall to install the ios version of Qt, please be aware that
+   there are compatibility issues between XCode 13+ and versions of Qt less than 6.2.4.
+   You may use aqtinstall to install older versions of Qt for ios, but the developers of
+   aqtinstall cannot guarantee that older versions will work on the most recent versions of MacOS.
+   Aqtinstall is tested for ios on MacOS 12 with Qt 6.2.4 and greater.
+   All earlier versions of Qt are expected not to function.
