Hi! It seems as if NativeGallery returns the image's path before it is written to the disk/while it is being written to the disk, but AFAIK this line ensures that image is written to the disk synchronously: https://github.com/yasirkula/UnityNativeGallery/blob/master/Plugins/NativeGallery/iOS/NativeGallery.mm#L482
Can you see any error messages in Xcode console? If you use the example code to display the selected image on a cube without using the ImageCropper plugin, does everything work properly?

Thanks for you reply!
I'll try to make the suggested modification without the ImageCropper and will get back to you ASAP!

Well, I've got a feedback: did all the tests and realized that there is something wrong with my logic (just couldn't figure out why it works perfect on Android and not on iOS). I'm attaching the sample bellow to see if there's something you can help with.
private IEnumerator CropPic()
{
yield return new WaitForEndOfFrame();
bool ovalSelection = false;
bool autoZoom = true;
float minAspectRatio = 1, maxAspectRatio = 1;
NativeGallery.Permission permission = NativeGallery.GetImageFromGallery((path) =>
{
Debug.Log("Image path: " + path);
if (path != null)
{
// Create Texture from selected image
texture = NativeGallery.LoadImageAtPath(path, 1024);
if (texture == null)
{
Debug.Log("Couldn't load texture from " + path);
return;
}
if (ImageCropper.Instance.IsOpen)
return;
}
}, LanguageManager.GetTranslation("SelectImage"), "image/png", 1024);
newProfileInstance.previousTexture = (Texture2D) newProfileInstance.profileImage.texture;
// If image cropper is already open, do nothing
if (ImageCropper.Instance.IsOpen)
ImageCropper.Instance.Hide();
ImageCropper.Instance.Show(texture, (bool result, Texture originalImage, Texture2D croppedImage) =>
{
if (result)
{
newProfileInstance.profileImage.texture = croppedImage;
if (croppedImage != null)
{
newProfileInstance.UploadImage(ConvertImageToBytes(MakeTextureReadable(croppedImage)), croppedImage);
croppedTexture = croppedImage;
}
}
else
{
croppedTexture = null;
}
},
settings: new ImageCropper.Settings()
{
ovalSelection = ovalSelection,
autoZoomEnabled = autoZoom,
imageBackground = Color.clear, // transparent background
selectionMinAspectRatio = minAspectRatio,
selectionMaxAspectRatio = maxAspectRatio
},
croppedImageResizePolicy: (ref int width, ref int height) =>
{
//width /= 2;
//height /= 2;
});
}

Oh, I see. You should just move ImageCropper.Instance.Show
(in other words, all the code) into the callback function of NativeGallery.GetImageFromGallery
, because the callback function is asynchronous on iOS and in your case, the assignation of the texture variable takes place after the ImageCropper.Instance.Show call.

It worked perfectly! I appreciate your work and your help! Thanks a lot!
