Xcode Build error (incompatible pointer)

[Noblauch]

After updating Mac OS to 11.4 and Xcode to 12.5 we can't build anymore!

We have a similar bug as ONTOPStudios. However the compile errors we are getting are different.
We get two incompatible pointer errors, that prevent the Unity project to compile:

Both errors are inside NativeGallery.mm
Error 1:

// Credit: https://stackoverflow.com/a/10531752/2373034
+ (void)pickMedia:(int)mediaType savePath:(NSString *)mediaSavePath {
	imagePicker = [[UIImagePickerController alloc] init];
	imagePicker.delegate = self; <––––– ERROR OCCURS HERE
	imagePicker.allowsEditing = NO;
	imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [...]

Error 2:

        [...]
	else { // iPad
		popup = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
		popup.delegate = self; <––––– ERROR OCCURS HERE
		[popup presentPopoverFromRect:CGRectMake( rootViewController.view.frame.size.width / 2, rootViewController.view.frame.size.height / 2, 1, 1 ) inView:rootViewController.view permittedArrowDirections:0 animated:YES];
	}
       [...]

I then updated native gallery, since I thought this was just a version issue, but the error stayed, I'm on the newest version.
We are blocked by this completely, I know this plugin is free and all, but any help for a workaround would be appreciated!

Your plugin is not up-to-date:

UnityNativeGallery/Plugins/NativeGallery/iOS/NativeGallery.mm

Line 574 in 0bc6c23

imagePicker.delegate = (id) self;

UnityNativeGallery/Plugins/NativeGallery/iOS/NativeGallery.mm

Line 615 in 0bc6c23

popup.delegate = (id) self;

I've downloaded the latest version from both GitHub and Asset Store on Unity 2019.4.26f1 and both of them were up-to-date. How could you download the latest version and not have the plugin up-to-date?

Hm strange, I updated via the package manager, and this is the newest version, I can't update any further, let me check!

[Noblauch]

Okay, I deleted the whole NativeGallery folder and reimported via the package manager, and the version still mismatches the fix. Hence the Asset Store / Package Manager version is not correct.

I downloaded the repository here on git and added the Native Gallery Plugin from there, now these errors are fixed, thanks for the lightning fast response!!

However now I'm getting the same errors as ONTOPStudios. I'll comment on that too. Thank you so far!

There must have been some sort of Package Manager cache issue because I've added the plugin via Package Manager to a new project and it was the up-to-date version.

But you are Using a GIT ref to the package. I get the content from the "My Assets" category of the package manager, since I got the plugin from the asset store. I'm not sure how to handle Asset Store Asset updates as a developer, but there is certainly an issue on the content there.

It must be some sort of cache issue. I've deleted Asset Store cache (just to be sure), downloaded 1.6.3 via Package Manager and the code was up-to-date.

Could you do this one test for me when you get the chance:

• Import the plugin via Package Manager on a new Unity project and see if the code is up-to-date
• If not, delete C:\Users\USERNAME\AppData\Roaming\Unity\Asset Store-5.x\yasirkula\ScriptingIntegration\Native Gallery for Android iOS.unitypackage, restart Unity and download the plugin via Package Manager again. Then see if the code is up-to-date

Indeed the code is up to date if I import it into a new Project. If you didn't upload anything in the meantime, there is probably some issue with the update workflow in existing projects. Though I never experienced something like this.
