VS 2019 Xamarin Forms support for iOS 9 / High Sierra

brischtbrischt Member ✭✭

Hi,

I'm quite new to Xamarin and starting a new project for an app that should support Android >= 5.0 and iOS >= 9.0.
After setting things up, it seems to me that the Xamarin version included in VS 2019 does not support High Sierra on the Mac building machine. So I have upgraded the mac to Mojave, with XCode and VS for Mac to the newest versions. So far so good, seems to work pretty well. However, I have noticed that the most basic app running on the iOS 9.0 simulator crashes, and after searching through some forums, it seems to me that Mojave does not support such an antique iOS in the simulator.
Is there any recommended way to make VS2019 work with High Sierra, or should I use VS2017? Or do you have any other suggestions and experiences for my setup?

Thanks for any wise words,

brischt

    @brischt It looks like a compatibility issue with XCode and Mojave.
    I read this forum post and found it to be similar to yours:
    https://forums.developer.apple.com/thread/108652

    However, it seems like the issue was fixed on referring the SO post from here:
    https://stackoverflow.com/questions/52500234/ios-simulator-crash-on-xcode-10/52500587#52500587

    Let me know if it helps.

    @AnubhavRanjan Thank you very much, unfortunately, this did not help. I have had a look at the simulator log which is quite extensive (and I have no idea what it all means); this seems the relevant part to me:

    Well yeah, lot of stuff, sorry for that.
    Generally speaking - is the iOS 9 simulator working for you on Mojave?

    Thanks,

    Hi @AnubhavRanjan ,
    first of all thank you for your hint. Unfortunately, it had no effect.
    I had a look at the simulator log (which is quite extensive) and the important part to me seems to be this snippet:

    Quite a lot, sorry for that. Do you have any idea what could be going wrong here?
    Or, generally speaking: Does the iOS 9.0 simulator work for you on Mojave?

    Thank you very much,

    brischt

    no it is not possible. you must use vs 2017 with earlier versions of xamarin.ios (maybe it is possible to use xamarin.ios older version with vs 2019 also, not sure).
    because latest xamarin.ios installed with vs 2019 requires latest xcode version and latest xcode version is only possible with maojave.
