Guys I really need your help. I was so concentrated running my game on iphone 5s device and I didn't realize that iphone 6 is running a little slower than the 5s and the 6 plus worst. What can I do for it?
This is a very common bug with the simulator a way I get around it is.
IOS Simulator: Window > Scale > 50% - it makes the simulator look like an actual device and it fits your screen perfectly.
Then I just leave the simulator open at all times rather then closing after I'm done testing my apps. This saves Xcode having to load all the simulators files and directories each time you run your app.
Hope this helps, cheers.
