Ios – ERROR ITMS-9000: “Unsupported architectures. Your executable contains unsupported architectures ‘[x86_64, i386]'”

If using Xcode 4.2 or higher, try the following:

1. Click your Project name (in the left column), followed by the Target:

   

2. Click the 'Build Settings' tab (in the right column):

   

3. Click the 'Release' or 'Distribution' row under 'Architectures', and choose 'Other...':

   

4. Double click the highlighted row named '$(ARCHS_STANDARD_32_BIT)' in the popover that appears, and replace it by typing 'armv6'. Then add a new row with the plus button in the bottom left of the popover, and type 'armv7', then click Done:

   

Update: you should add armv7s to target the iPhone 5 as well. (And drop armv6 if building with Xcode 4.5 or higher, which no longer supports armv6.)

That's it. You should now be able to build/archive without generating errors.

If it still doesn't work, see this answer from justinxreese, which suggests adding entries for armv6 and armv7 under "Required Device Capabilities" in your info.plist file.

I'd go with Java Swing Tutorial. This should introduce you to some easy examples of GUIs and give you some cool widgets to place with.

Also, if you're looking into buying books, I know that the Head First book series do a very good Java Book which is what I first read to introduce me to it. It has a very good GUI section where you make a music player. Very well written, and in some parts humorous book. Worth the money, I'd say!
