Not working on iOS after 1.8.116 - Attempting to JIT compile method '(wrapper delegate-invoke)

[Dizmus]

Steps to reproduce:

1. Create Xamarin.iOS application
2. Create SQLAsyncConnection
3. Access Entity via Table().FindOneAsync

Error:

Attempting to JIT compile method '(wrapper delegate-invoke) void :invoke_callvirt_void_UserInfo_Guid (Skandy.Mobile.Domain.UserInfo,System.Guid)' while running in aot-only mode.

[lukealderton]

I'm having the same issue as above, I've tried, .Table().Where(x => x...) and .Query("query"), same issue, also with using 'ugly' I thought it might solve the issue, but still getting the same issue

[paul-kiar]

There has been no response on this so I'll share my diagnosis:
FastColumnSetter was added 2 years ago in the code.
2 months ago PR #1059 was committed to the codebase.
In that PR a line was added to use MakeGenericMethod.
This is fine for anywhere that JIT is allowed, but on iOS if you have Link All Assemblies set (Release Mode) then it cannot work because it needs to create some code for the generics in question. This is not allowed in AOT mode on iOS.

[inforithmics]

pull request with workaround

#1064

[ElteHupkes]

I think you're spot on @paul-kiar, MakeGenericMethod is basically guaranteed to fail on iDevices (unfortunately it works fine on simulators, which is probably why this is always caught late). Until now I was under the impression that the fast setters would work in this case because they were limited to hard coded simple types, but it seems there's still something devious going on that makes MakeGenericMethod necessary. Think I'll have to downgrade for now.

[inforithmics]

I don't think that this is the problem because the MakeGeneric fixed this case
... .ExecuteDeferredQuery<object>(new TableMapping(typeof(ClassB))).ToList();
where object was added as the Type to fill.
This carshed with the Delegates because it tried to set properties on the object type which cannot work.
Like this.

object a = new object();
a.test = "test";

Besides The Version before already had this Compilation Bug. The workaround would be to AOT Compile with enabled Interpreter but this doesn't work because of another Bug.

mono/mono#20417

Which seems not been merged yet into the release mono runtime.

[inforithmics]

I think the real solution for fixing this would be to write a Source Generator that uses the interface that I have added in this pull request. Then It will be even faster and AOT safe.

#1064

[AppsmithsLLC]

It may not work for everyone, but I downgraded to 1.7.335 and my queries are working again.

[StepKie]

It may not work for everyone, but I downgraded to 1.7.335 and my queries are working again.

This worked for me too.

I landed here after almost going insane trying to figure out why our app was failing at runtime, since it works fine in debug mode on a simulator. Being very grateful for all the work that has gone into this project already, I hope @praeclarum finds the time to update this library or incorporate the already existing PR since this is the de-facto standard for local storage on mobile devices (Xamarin developer here), and I would assume a lot of developers are affected.

Best regards & Thanks

Also facing this issue after updating to 1.8.116. Downgraded back to 1.7.335 as a temporary workaround. If it helps, here is my stack trace:

UPDATE: I wanted to add that the exception is only thrown, if the project setting Enable the Mono interpreter is disabled (which should be typically the case for the Release-build). You will not see the exception in Debug-configuration.

[paul-kiar]

The existing PR doesn't really fix the problem, it just pushes the optimization of the generated run-time compiled code onto the consumer programmer. Maybe there is a way to compromise where the performance is increased but there doesn't need to be run-time compiled code. Try to generate code, if the platform doesn't support it fail over to the old way. Or maybe some way of providing a generic method on your class that will set the property without boxing.
