Can't access files from Swift

[RomeuG]

Hello!

This is a very similar issue to #80 .
Regardless, it is being added as Embed&Sign and yet, when I try to access the files through the debugger, I get this:

(lldb) p MR.files().testfile
error: Execution was interrupted, reason: internal c++ exception breakpoint(-4)..
The process has been returned to the state before expression evaluation.
(lldb) p MR.files().testfile
(ResourcesFileResource) $R0 = <uninitialized>
(lldb) p MR.files().testfile()
(String) $R2 = ""
(lldb) 

If I try to access it through the Kotlin MPP shared code, a NullPointerException is guaranteed:

Everything works fine on Android and in both platforms the MR stuff generation is done.

What could be causing this?

Thanks.

Edit:

It seems the NullPointerException comes from loadableBundle() extension from Moko-Resources.
But I do not know which line specifically. Could be return NSBundle.bundleWithIdentifier(identifier)!!.

I should also say that the iOS app is being ran on iOS 14.

Is this project still active?

[Alex009]

@RomeuG hi.
looks like bug in bundle search or bundle embeding in framework.
can you check on sample https://github.com/icerockdev/moko-resources/tree/master/sample/ios-app - this problem reproduced here on your environment? if not - please try modify sample to reproducer. or give your own reproducer project please.

[RomeuG]

@Alex009 Hey!

Thanks for responding! :-)

Sometime this week I will try your Sample. Unfortunately, I am not able to provide the reproducer project.
I will report back after testing the sample.

[RomeuG]

Sorry, other things had priority over this.

Finally I tested the samples.
They work, even on iOS 14.

It seems the problem is on my end.

Regardless, I will be trying to fix this on my project and I will report back with the solution.

[RomeuG]

@Alex009

I have made a project with the bug:

https://github.com/RomeuG/moko-resources-sample-bug

It is kinda confusing with the names and such, but I hadn't much time to prepare it.
Are you able to run it?

Edit: Should be opened with Xcode 12.0

[Alex009]

@RomeuG big thanks for demo projec! i will debug problem on next week

[RomeuG]

No problem, really. I hope it serves you well and I also hope it is more than enough for you to actually be able to solve the problem.

If you want me to change anything or have any question about the sample project, don't hesitate to ask! :-)

[Alex009]

i think problem solved here 9b02f36

maybe i do 0.11.2 release with this fix on kotlin 1.3.72

[RomeuG]

Hey!

That's great, thank you very much for the fix. I will have to try it on a 0.11.2 release... that would be awesome! :-)

EDIT: the fix for kotlin 1.3.72 is in my interest. Would you be able to do it?

[Alex009]

@RomeuG hi! are you try 0.11.1 version? it resolve your issue?

[RomeuG]

@Alex009 Hi! Yes, it did solve my issue! Thank you very much! :-)
