Xcode 9 Crashing while setting a Texture in SKScene in Spritekit

Question

I am building a game in Spritekit with Xcode currently. After updating to Xcode 9 I've found that every time I set a texture through the .sks file, Xcode crashes instantly. I've restarted my computer, updated the app, reloaded the textures and nothing changed. I have the 2017 Macbook Prof 13" w/ touch bar. Here are the diagnostics:

Answer 1

I solved the crashing problem.

The problem is with your @2x and @3x images. With those present in your Assets.xcassets folder - the SKS node will crash XCODE.

1. Add ONLY the 1x image to your Assets.xcassets folder.
2. place a Color Node onto your SKS scene.
3. select a texture
4. resize the texture.
5. add your @2x and @3x files later.

This solution works 100% each and every time.

Answer 2

OHM，我发现原因如果你的图像与故事板上的skspritenode当前大小的比例不相等就会发生这样的事情！

Answer 3

Strip the metadata from the image before setting it as texture.

For example, using ImageMagick :

convert oldImage.png -strip newImage.png

Answer 4

I found cleaning the build worked once and prior to that I put the images in photoshop and exported them as PNG's and then put them in the assets folder and that seemed to work for a while. But since Mojave and the latest Xcode update, that doesn't seem to work anymore. I've already submitted 3 crash reports to Apple and it's taking me nearly an hour to get 2 sprites with the right textures on the screen. Don't mean to sound rude, but Apple need to stop being a bunch of oranges on this one and get is fixed ASAP!!

Answer 5

I found a workaround that may or may not work, it ain't reliable but still better than not working at all. I created an empty SKS file and set all my textures in this file. I then copied and pasted the node into the preferred SKS file.

Answer 6

There is a great workaround on the Apple forums.

How to fix your .sks file :

• Open your .sks file outside the project (close your project and open the file directly from Finder)

• You should see red crosses instead of the Sprites, delete the Texture name information for all of them.

• Now, you should be able to reopen the file from the project.

• Finally, reenter the Texture name for all your Sprites.

Answer 7

I was having this problem with only one of my sprite textures causing the Xcode sprite editor to crash (even after removing the @2x and @3x images). It had an image DPI of 300 pixels/inch. I changed it to 72 pixels/inch which matches the other sprite textures. No more crash.

I hope this helps someone. This bug in Xcode's sprite editor has been around for quite a few versions of Xcode and is a real productivity killer. Keep submitting those bug reports to apple.

I think it is due to your computer: MacBook Pro (13-inch, 2017), which is also my workstation now.

I have tested the same project (simply created by the game template with an identical texture image) on the following computers with Mojave 10.14 and Xcode 10.1 installed:

Mac mini server( later 2012) iMac, 27 (Middle 2011) MacBook Pro, 13 (Middle 2014) MacBook Air, 13(Middle 2014) MacBook Pro, 15(Middle 2014) All of the above computers work well.

One more weird thing happens when I project my MacBook Pro(13-inch, 2017) through the AirPlay, it does not crash anymore.

Answer 9

I had the same issue and what worked for me was to bypass using .xcassets all together. I simply added a folder to my project and imported the images into the folder. After that, assigning texture in the scene editor no longer crashed Xcode
