    The project output for iOS with Unity2020 series cannot be started on iOS12.4.

    After creating an empty project and changing the Platform to iOS, when I start the iOS12 simulator with Xcode, the splash screen does not appear and it does not progress from the black screen.

    Unity2021 will have the same behavior and will not be playable.
    I confirmed that Unity2019 can be started even with iOS12.4.
    Did you need any additional settings for building iOS from Unity2020?

    Here is the log when running in Xcode

    starting with 2020.something openGL ES is no longer supported by unity, i.e. it is either Metal or so called "null device" (no rendering is done) which happens in your case:
    Code (csharp):
    1. GfxDevice: creating device client; threaded=1
    2. NullGfxDevice:
    3. Version: NULL 1.0 [1.0]
    4. Renderer: Null Device
    Metal on simulator requires xcode11 and macos 10.15. Since xcode11 is required i would assume you need to target ios13 on simulator (but i am not sure honestly)

    > Unity's system requirements say 2020.3 is "iOS11", but does this only work from iOS13?
    this is kinda unrelated. Your problem is that when run on simulator metal cannot be used (for some reason). Did you try using newer ios version on simulator?
