Symbolicate crash log - XCode 7.0.1

I am trying to symbolicate the crashed log & tried variuos methods.

1) symbolicating crash log from xcode(7.0.1) > Devices > All Logs > Re-Symbolicate logs

Nothing happens

Installed command line tools, xcode-select --install

export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer

2)from command line, symbolicate “Crash.crash” "MyApp.app"

Got error, symbolicate: command not found

3)/Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash ~/Desktop/Crash/Crash.crash ~/Desktop/Crash/MyApp.app.dSYM

Couldnt find any DTDeviceKitBase.framework

4) atos -arch armv7 -o ~/Desktop/Crash/MyApp.app/MyAppName 0x00000001001de44c 0x1000d0000 + 1107020

Got log, but not showing excat issue.

Just to verify my step 4 result is correct or not, I treid making crash by simply writing below code

NSArray *arr = [NSArray arrayWithObjects:@"1", @"2", nil];
NSLog(@"Here - %@", [arr objectAtIndex:5]);

But, after symbolicating crash log using step 4, Its shows [classname functionName] of some different class only. This makes me think that the symbolicated log of step 4 is not correct.

Edit 1: Adding crash log
