Hi guys!

I am still very new to iOS development. Currently trying to learn core data. A quick thank you to all the high quality tutorials on this website. I have learn a lot from you all!

Every time when I am switching from code page to storyboard, it freezes for a few seconds before it loads. However in all the video tutorials, you guys don’t seem to have this problem.

I am currently using a 15" mac pro mid 2014 version. graphic card is Intel Iris Pro 1536 MB. I was simply doing all the basic tutorials, and I thought it should be powerful enough to run everything smoothly.

Just wondering is there any trick to make running storyboard faster?

Thanks!

kind regards,  
Simon Tsang

Listening to numerous iOS development podcast, this is a common issue. If you close Xcode and reopen it, the issue should temporarily go away. If you check the CPU usage on your Mac, it is likely at 100% or higher. One dev on a podcast said theirs was showing 400% CPU usage. Xcode 9.0.1 is supposedly better than 9.0.0, but I would imagine future releases will be better.
