iOS I have three errors that wont go away!--HELP! (PLEASE)

I am pretty new to developing but I do know a thing or two...but there is a problem. I downloaded the iphone sdk and started using xcode. I open a blank project (window based application) and as soon as I open it I press "Build and Go" I HAVE THREE ERRORS!!!

1. Unable to create directory /var/folders/Rj/RjhRY3mPFz0kvyqJCUd6rE+++TM/-Caches-/com.apple.Xcode.502/SharedPrecompiledHeaders/untitled_Prefix-dsjprbsmyrrytwddlihxssjkwmgo

2. error: couldn't create directory /var/folders/Rj/RjhRY3mPFz0kvyqJCUd6rE+++TM/-Caches-/com.apple.Xcode.502/SharedPrecompiledHeaders/untitled_Prefix-dsjprbsmyrrytwddlihxssjkwmgo: Permission denied

3. /Users/Jonah/Desktop/untitled/untitled_Prefix.pch:1: fatal error: can't create precompiled header /var/folders/Rj/RjhRY3mPFz0kvyqJCUd6rE+++TM/-Caches-/com.apple.Xcode.502/SharedPrecompiledHeaders/untitled_Prefix-dsjprbsmyrrytwddlihxssjkwmgo/untitled_Prefix.pch.gch: Permission denied



THE weirdest part is that when I go to untitled_Prefix.pch and get info and click "make file localizable" the third error goes away. Thank you so much to anyone that can help!

It sounds like it could be a bad install of the sdk. Have you tried reinstalling it?

I had the dmg file saved and tried reinstalling that way but it did the same thing. Should I download it again?

Please someone help!

Ok, I tried re-downloading and re-installing xcode and everything on the iphone sdk and STILL don't know whats wrong! Please help me!

Finished verify/repair permissions on disk disk0s2 Macintosh HD

Fixed!

Just in case anyone is wondering...I found a solution to the problem. I looked at the errors and they all had to do with some folder in var/folders/.....etc...well anyways, i showed all hidden files on my computer, went to that folder that it was talking about and set it so everyone on the computer has permission to read&write. then i clicked "build and go" and everything was GREAT!!!! thanks for anyone that helped....
