This possibility is especially interesting for iOS music and audio processing apps that can work as an Audio unit (AUv3) and are adapted for use with macOS.
Many (but not yet all) DAWs and audio unit hosts on Mac already support the new format of audio plugins - AUv3 (do not confuse with regular AU plugins). Among them - Ableton Live (from version 11.2), Logic Pro, GarageBand, MainStage, Cockos Reaper, Plogue Bidule, Hosting AU, etc. With these hosts, iOS apps can work just as well as regular plugins.
But once again, the iOS audio apps must comply with the AUv3 standard and be adapted to work with macOS. In the App Store, the descriptions for each app have labels to tell you what platform the app was designed for. Many apps will also have a label that says, “Not verified for macOS,” which means you may encounter performance or interface issues while using it.
From these articles you can learn how to run iOS apps on Mac. Note that you do not need any third-party soft to run iOS apps adapted and verified for macOS on Macs M1 (and later).

Please note that on your Mac should be enabled System Integrity Protection (SIP) to open iOS apps.

There is also an interesting article for fans of Ableton Live - "Why iPad Music App Support in Ableton Live is so Awesome". Here you can replace Ableton on any other DAW that supports AUv3 plugins. For example GarageBand or Logic Pro.

Another interesting option to use iOS audio apps on Mac standalone, even without AUv3, is routing audio between them. For this, you will need a third-party software on Mac that provides audio routing. There are several free and paid virtual audio routing apps for macOS.
This article lists popular options and gives an example of using such apps with Ableton Live.
