iOS device build error in 1.2.1.1

[emendamus]

Hello,

as soon as I am trying to create a release build for an iOS device am getting the following compiler error:

Error MT2002: Failed to resolve "System.Void Couchbase.Lite.Storage.SQLCipher.AOTHelper::TrickLinker()" reference from "Couchbase.Lite.Storage.SQLCipher, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"

On simulator everything works great.

I tried it even with a fresh project.
Just added the dependencies and created a database.

You mean creating a release build of the library? Or do you mean creating a release build with a project using the Nuget package?

[emendamus]

I mean creating a release build with the Nuget package.

So finally I could resolve that issue by the following steps:

• upgrading from ios sdk 9.2 to 9.3
• changing the link behaviour to "don't link"

If I say 'link sdk assemblys only '' I get with SDK 9.3 the following error message:

Failed to resolve assembly: 'SQLitePCL.ugly, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'

I will add a note to the storage engine overview that you need to use "Don't Link". That's the way I test the package, and I didn't think to change it. I will consider making more changes to the way the plugins work for the next release.

[emendamus]

Okay, perfect!

One last question:

Is there a way to reduce the size of the app. So after changing the link behaviour the app size is very huge and I get the following message from iTunes connect:

ERROR ITMS-90122: "Invalid Executable Size. The size of your app's executable file '.....' is 72482816 bytes for architecture 'armv7', which exceeds the maximum allowed size of 60 MB."

[borrrden]

Not sure on that one. I'll try something real quick but if it doesn't work I'll have to post a question on the Xamarin forums. I imagine they have some kind of argument you can write into the custom flags area.

Wrote this -> https://forums.xamarin.com/discussion/65752/how-to-get-mtouch-to-ignore-an-assembly

I'll try to figure out a workaround. The best so far is that I need to recompile the storage engines with the dummy code inside of them and have users like you include all three storage engines. This is not an ideal solution though. However, if I switch to manual registration then this hack will be unneeded (and compile times should be faster I think). I'll put this high up on my list of things to do and point you to a CI build once it's done. The bad news is I will be out for half of next week so this will be a bit slow.

[emendamus]

Wow, thank u for your quick response !

[borrrden]

@emendamus This fix is a part of CI build 18 http://latestbuilds.hq.couchbase.com/couchbase-lite-net/1.3.0/18/

I tested it and with the link SDK only option my sample app went from about 60MB to 20MB.

[emendamus]

@borrrden Thank u for fixing that problem!

But I am getting now this message:

Failed to resolve assembly: 'websocket-sharp, Version=1.0.2.23571, Culture=neutral, PublicKeyToken=null"

Where do I get this assembly?

[borrrden]

Hmmm that should be included in the package but maybe it didn't make it in
somehow. I'll check it out keep an eye out for new builds.

I confirmed it was missing in build 18, but it's there in build 19 and I was able to consume build 19 in my sample app.

[emendamus]

It is finally working.
Thanks!

@borrrden: Do you have an ETA for 1.3 or 1.2.2? We'd like to get this fix, but avoid custom repository URLs if possible. Publishing a pre-release package would be enough for us.

[borrrden]

@kibiz0r RIght now we are on track for next Friday (1.3). We may or may not have a preview before then, I'm not sure.

This is also affecting me as well however I'm getting a slightly different error when I build to a device and linking is set to "Link Framework SDKs Only". I'm using v1.2.1.1 with Xamarin.iOS 9.6.2.4

MTOUCH: Error MT2002: Failed to resolve "System.Void Couchbase.Lite.Storage.SQLCipher.AOTHelper::TrickLinker()" reference from "Couchbase.Lite.Storage.SQLCipher, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" (MT2002)

The error goes away if we turn Linking off however we can't do that in our production app. Its already about 50MB with linking turned on.

I am going to download the source for 1.3 and try that. However, @borrrden it would be awesome if we could grab a pre-release from nuget.

@borrrden I tried to use build 197 from here: http://latestbuilds.hq.couchbase.com/couchbase-lite-net/1.3.0/197/ but I ran into that web-socket build issue that happened to @kibiz0r

i was able to get past this by using build 19 from http://latestbuilds.hq.couchbase.com/couchbase-lite-net/1.3.0/19/ as well so perhaps there's a regression that's causing that issue to re-appear in build 197

to add the latest findings... build 19 had issues with the forest db at build time that I wasn't seeing at first. trying 130 now and that seems to be working better. had to add the SQLitePCL packages manually.

@kentpickard did you get it to work?

I am getting an error on build 134: Couchbase.Lite.CouchbaseLiteException: No implementation found for SQLite storage

[kentpickard]

@chr22 yes it does seem to be working but perhaps not totally stable. I have my fingers crossed that an official 1.3 version will come out soon.

is one of the errors listed here? https://github.com/couchbase/couchbase-lite-net/wiki/Error-Dictionary

I believe you need to add a line of code to register the particular storage engine you want. I am using ForestDb.

[chr22]

@kentpickard thanks a lot.

Now it works, it seems I hadn't registered my storage engine.
