It is difficult to understand your problem, so I will reformulate.
Tell if I understand correctly and please answer the questions.
In previous version XCode 8 , in lauchscreen story board i add uiimageview in window and the image name , when lauch app show the image.
- in previous XCode : 8.0 ?
- you have a launchscreen with an imageView inside
- when you run the app it is OK. Is it in simulator or on real device ?
Now in XCode 8.1 the old image present in Asset show well when run device , but the new image add afther update Xcode not show in run device, but if set UIImage in viewController and set the identy image show !
- You have one image in asset catalog ?
- You speak of the old image. What is the new image ? Is it in asset catalog also ?
- This image is displayed in the launchscreen when you run the app : Is it in simulator or on real device ?
- Do you want the new image or the old image to show in launch screen ?
- I do not understand your last sentence at all : but if set UIImage in viewController and set the identy image show !
