iPhone SDK Always Loading

Downloaded the latest build from here, unzipped it, and added the 1.4.1 directory to /Library/Application Support/Titanium/mobilesdk/osx.

"Loading" problem is no longer there but when I select SDK 3.2 to launch my app in it brings up an iPad simulator. Needed to use SDK 4.0 to launch the iPhone simulator.

Titanium is compatible with iPhone SDK version 4. What the "loading…" text usually means is that Titanium Developer does not see the Xcode tools on your system path. If you go to your terminal and run "xcodebuild" and nothing happens, then probably your path is not configured correctly and you'll have to put /Developer/usr/bin on your path (this SHOULD have been done by the Xcode installer automatically). To correct this, you could also reinstall Xcode and the iPhone SDK, but this might be considered a 'nuclear option'.

If adding the tools to your path doesn't work, run the following from a terminal:

~/Library/Application\ Support/Titanium/mobilesdk/osx/1.4.0/iphone/prereq.py project

Should see:

If not, paste the output and we can see what might be up.

Oddly enough it says "Missing Apple XCode"… I guess I will be reinstalling the SDK then. I'll report back in a few hours after it downloads… Thanks!

Even after reinstalling the SDK it still says {"success":false,"message":"Missing Apple XCode"}… Any ideas?

Ok, so I readded the /Developer/usr/bin folder into the $PATH, but it still stays "loading" forever. What should I do at this point?

I'm still geting a constant "Loading…", too. My app won't run at all in the emulator. I did everything listed here and installed the new patch from last night. I get this when I run prereq.py: {"success":true, "sdks":["4.0","3.2"],"ipad":true}
My prereq.py wasn't under my home dir so I created a link to it. Any help or ideas would be appreciated.

This just started happening to me as well. Was working fine since I first installed a couple weeks ago. I was in the middle of working on an iPhone app, went back to Titanium to the Test&Package tab and SDK was Loading…

I have reinstalled, no dice. Really don't want to reinstall iPhone SDK if I don't need to.

prereq.py reports:
{"success":true, "sdks":["4.0","3.2"],"ipad":true}

Upgraded my Macbook to Snow Leopard 10.6.4, installed xcode 3.2.3, and ios sdk 4.0.2. Installed Titanium and followed the GettingStarted(Mac) pdf. Mobilesdk was still 1.2.0. Tried to run on the iPhone emulator and it shows the "sdk" textbox as "loading". Clicked on launch anyway and got this log:

[INFO] One moment, building …

Okay, so now I download and install mobilesdk 1.4.0, restarted Titanium. SDK still shows "loading" and the log when I try to launch is this:

Any ideas?

Also when I toggle the output it shows this:

my log is as below after I run prereq.py:

Ideas?

I installed the system updates last friday, before doing updates, My TiDeveloper works well with iPhoneSDK4.0, after that, the loading of iPhoneSDK seems waiting forever.

I'm having the same problem. Did a fresh install of TiDeveloper, upgraded to 1.4.0 and reinstalled the XCode/SDK.

xcodebuild is in my path; the output is:
```
xcodebuild
xcodebuild: Error: the directory /Users/foo/appcelerator/helloworld does not contain an Xcode project.
```
And I get the following from prereq.py:
```
 /Library/Application\ Support/Titanium/mobilesdk/osx/1.4.0/iphone/prereq.py project
{"success":true, "sdks":["4.0","3.2"],"ipad":true}
```
And I still get the continual Loading… message inside of TiDeveloper. Any ideas?

@Andy Wang: I think you need to give prereq.py the literal argument project, instead of the name of your project (EQ31Formulas).

I am now using 1.4.1 as of build: Sep 4 2010 22:11 rdc0620a5 From
http://builds.appcelerator.com.s3.amazonaws.com/index.html
I no longer get the perpetual: SDK: loading…

— commented September 6th 2010 by Ron Burns
I get the same output, true, sdks 4.0 and 3.2 ipad true. After this I have changed the Titanium sdk version at the edit window (helloworld and kitchensink). Now it shows the sdk version

— commented September 19th 2010 by Marco van Zomeren
I did what Marco said, (I changed the Titanium SDK version to 1.6.0) and now i can build and run my iPhone app. But I had to run prereq.py as mentioned above.

— commented February 16th 2011 by Joan Lindhout

I just found a similar thread on this site, which indicates the problem is caused by the recent iTunes 10 upgrade. Making the suggested change to prereq.py has done the trick for me and the iPhone emulator is working again.

I had a similar case, finally, all I had to do was

select the project in the "project pane",
click on "Edit" from the top menu, then
select "1.6.2" in the Titanium SDK,
save changes and you're done :)
