This is how to activate app using AppleScript.
NSString *command = [NSString stringWithFormat:
@"try\n"
@"tell application \"%@\"\n"
@"activate\n"
@"delay 0.5\n"
@"tell application \"System Events\" to tell process \"%@\"\n"
@"tell (first window whose subrole is \"AXStandardWindow\")\n"
@"set fullScreen to value of attribute \"AXFullScreen\"\n"
@"if fullScreen = true then\n"
@"set value of attribute \"AXFullScreen\" to false\n"
@"end if\n"
@"end tell\n"
@"end tell\n"
@"end tell\n"

@"tell window %d\n"
@"set {position, size} to {{%d,%d},{%d,%d}}\n"

@"end tell\n"
@"end tell\n"
@"on error errMsg number errorNumber\n"
@"return \"Error with number: \" & errorNumber as text\n"
@"end try", ownerName, ownerName, ownerName, idx, (int)rect.origin.x, (int)rect.origin.y, (int)rect.size.width, (int)rect.size.height];
NSDictionary* errorDict;

NSAppleEventDescriptor *stringDescriptor = [listDescriptor descriptorAtIndex:i];
if ( stringDescriptor.stringValue == nil ) continue;

This is how to activate app using AppleScript.
In Instrument, leak happend at "NSAppleEventDescriptor listDescriptor = [returnDescriptor coerceToDescriptorType:typeAEList];"
---- src below ----
NSString command = [NSString stringWithFormat:
@"try\n"
@"tell application "%@"\n"
@"activate\n"
@"delay 0.5\n"
@"tell application "System Events" to tell process "%@"\n"
@"tell (first window whose subrole is "AXStandardWindow")\n"
@"set fullScreen to value of attribute "AXFullScreen"\n"
@"if fullScreen = true then\n"
@"set value of attribute "AXFullScreen" to false\n"
@"end if\n"
@"end tell\n"
@"end tell\n"
@"end tell\n"
@"tell application "System Events"\n"
@"tell process "%@"\n"
@"tell window %d\n"
@"set {position, size} to {{%d,%d},{%d,%d}}\n"
@"end tell\n"
@"end tell\n"
@"end tell\n"
@"on error errMsg number errorNumber\n"

I try not to do next if scriptObject nil (src as below)
" NSAppleScript* scriptObject = [[NSAppleScript alloc] initWithSource:command];
if( scriptObject == nil )
return false; "
But "scriptObject == nil" not happened.
I inspect memory leak by Xcode Instrument and find "NSAppleEventDescriptor coerceToDescriptorType" allocate lots of memory.
Could you help us how to free it?

The first time you fire up NSAppleScript that’ll allocate a whole bunch of memory for that subsystem.
-> Is there a way to avoid allocating a bunch of memory? How to release memory when end of NSAppleScript command?

I test NSAppleScript to move desktop windows, src as below.
And memory increase faster when moving windows.
When stop moving window, memory usage increase as well.
It seems memory not be released somehow.
NSString *command = [NSString stringWithFormat:
//@"#!/bin/bash\nosascript <<EOF\n"
@"try\n"
@"tell application "System Events"\n"
@"tell process "%@"\n"
@"tell window %d\n"
@"set {position, size} to {{%d,%d},{%d,%d}}\n"
@"end tell\n"
@"end tell\n"
@"end tell\n"
@"on error errMsg number errorNumber\n"
@"return "Error with number: " & errorNumber as text\n"
@"end try", ownerName, winIdx, (int)rect.origin.x, (int)rect.origin.y, (int)rect.size.width, (int)rect.size.height];
NSDictionary* errorDict;
NSAppleEventDescriptor* returnDescriptor = NULL;
NSAppleScript* scriptObject = [[NSAppleScript alloc] initWithSource:command];
returnDescriptor = [scriptObject executeAndReturnError: &errorDict];

I do memory inspection by Activity monitor.app
