The script seems to fail to generate proper build script

[InfiniteCode]

Trying to generate bindings for RichEditorView cocoapod. Seems like the build script is not fully generated:

#!/bin/bash
set -e
rm -rf packages-tmp/*.*
rm -rf packages-good/*.*
rm -rf packages-raw/*.*
nuget sources Remove -Name DT.Automatic || true
nuget sources Add -Name DT.Automatic -Source /Users/username1/Projects/objc-automatic/bindings/packages-good

Is there any reason why it fails?

[alexsorokoletov]

@InfiniteCode check if you have latest version of NuGet. I will check what's going on with this specific cocoapod.

[InfiniteCode]

I do have the latest. What is surprising, running any of the pods - lottie-ios, or any other one results in the same half-finished script. Seems like dependency graph is not populated, so it never iterates through the list.

[alexsorokoletov]

RichEditorView is a swift-based pod. I did not plan to support that initially. Because of that generating C# code and getting binary fails with error [!] Pods written in Swift can only be integrated as frameworks; add 'use_frameworks!' to your Podfile or target to opt into using it. The Swift Pod being used is: RichEditorView Checking what we can do there, will update in a while

[alexsorokoletov]

@InfiniteCode would you be kind as to run sh bind.sh POD=lottie-ios VERBOSE and send a link to gist with the logs or attach a log file here?

I am still checking if there is a way to make objc-automatic to work with swift-based cocoapods

[alexsorokoletov]

Hey. So there are couple minor problems with Swift frameworks in cocoapods and also with this specific RichEditView pod.

1. RichEditView is a Swift-based pod
2. RichEditView spec references version of pod written in Swift 2.3 while latest XCode only understands 3.0 and requires project conversion. You have to do it manually :(
3. Since Swift cocoapods compile into framework, you have to make some adjustments to the tool objc-automatic to make it at least generate the binding project.
4. When objective sharpie is trying to infer the C# api based on Objc headers for Swift framework it gets many things incorrectly because Objc headers for Swift are not exactly same as for just normal Objc-based pod. That's fine, you can figure it out. Basically, one has to remove initWithCoder bindings and update Delegate properties and comment WeakDelegate properties.

And that is all, binding is generated and packaged into the nupkg.

Would be great if you can check this package and see if it works for you. Meanwhile I can update the objc-automatic so everyone can follow the process.

Glad that you brought up this issue @InfiniteCode. That is actually a first example of making Xamarin binding to Swift library. With updated objc-automatic, it will be easy.

[InfiniteCode]

Hey, do you still need me to run that script with VERBOSE logging? I could probably do it today in the evening. And thanks so much for pre-baked bindings!

[InfiniteCode]

Unfortuntely, when tried to build with the provided binding it failed at linking phase. It was also strange that after added a Nuget package, I had to manually go to the project and pick the DLL. Otherwise, it wouldn't see the namespace and classes: /Users/username1/Projects/iOS/MTOUCH: Error MT5209: Native linking error: file not found: /Users/username1/Projects/iOS/obj/iPhoneSimulator/Debug/mtouch-cache/RichEditorView.a (MT5209) (iOS)

Is there something else that is needed for binding to work? (Or maybe it wasn't built for Simulator)

[InfiniteCode]

@InfiniteCode bindings should be built for simulator and device. Can you share a sample app that uses this editor so I can check if these bindings work at all?

On the log, it is strange to see that:

VERIFY: pod lottie-ios doesn't have any binaries generated for config -sdk "iphoneos"
VERIFY: pod lottie-ios most probably doesn't have any binaries generated

I'll think what information could I need to find what's going on. What XCode version do you have? Do you use latest master code for objc-automatic?

[InfiniteCode]

XCode is 8.2.1, objc-automatic and sharpie are the latest from master.

username1$ xcodebuild -version
Xcode 8.2.1
Build version 8C1002

I will create a sample app later today.

[InfiniteCode]

@alexsorokoletov Here is the sample project which doesn't compile. It was a strange behavior as well during nuget install. I added it to the packages list and clicked restore. It did find it in the local repo, and added to the project.

However, it didn't add a DLL to the references in project preferences. So, I had to manually go there and add it, so it can start seeing the namespaces.

[alexsorokoletov]

Checking.

[alexsorokoletov]

My mistake, package was build in kind of a mixed mode and I had to edit .linkwith.cs file to make sure it references RichEditView.framework but not RichEditView.a

Also, I tried installing this package in your solution (I removed bad package and added freshly built from my internal nuget source) and it added reference just fine.

I have checked and now solution compiles for Simulator but does not for device

 ld: warning: linking against a dylib which is not safe for use in application extensions: /Users/alex/Downloads/REVTest/REVTest/obj/iPhone/Debug/mtouch-cache/RichEditorView.framework/RichEditorView

    clang: error: linker command failed with exit code 1 (use -v to see invocation)

I feel like compilation from cocoapod to framework should be better, need to work on that.

[alexsorokoletov]

@InfiniteCode I will have some time later this week to look at this. This is really interesting topic and I feel like we can easily add support for swift-based cocoapods. How "easily" is undefined yet.

[InfiniteCode]

@alexsorokoletov Very appreciated! Need that one badly :)

[InfiniteCode]

@alexsorokoletov Hey Alex, is there any progress on this matter? Thanks!

[alexsorokoletov]

Looking at this today, @InfiniteCode

[alexsorokoletov]

@InfiniteCode I was not able to make this work. Simulator build is still crashing and device build cannot AOT the dll. Following this documentation and samples but can't find what's wrong.

Complication to all this, RichEditorView is in Swift 2 originally so I am not sure how XCode updated it to Swift 3. Unfortunately, there is nothing I can do now.

My best guess would be to follow the documentation on Swift bindings for Xamarin and do the bindings manually. objc-automatic can't help with cocoapods written in Swift (yet).

[InfiniteCode]

@alexsorokoletov Ah ... it's a pity. Anyway, thanks for trying!

[InfiniteCode]

@alexsorokoletov I decided to use a different library, which is not Swift based. Having troubles with it as well: ZSSRichTextEditor

On the bright side, it was able to generate proper binding build script. However, once launched it started throwing some undefined references:

error CS0246: The type or namespace name `IHRColorPickerViewControllerDelegate' could not be found. Are you missing an assembly reference?
error CS0246: The type or namespace name `ZSSBarButtonItem' could not be found. Are you missing an assembly reference?

It seems that some of the dependencies were not properly detected. Here is the initial bind POD output:

I tried temporarily to comment out those lines and building ended up failing on another error:

Is there something else to be done or modified to make it working?

Thanks!

[alexsorokoletov]

These are Xamarin.iOS binding errors. You have to adjust ApiDefinition.cs file manually to resolve these errors. My guess regarding IHRColorPickerViewControllerDelegate would is that you should just add in the very beginning of the ApiDefinition.cs file

public partial interface IHRColorPickerViewControllerDelegate { } and that's it.
