The xib compiler in Xcode 5.0.1 always sets the scaling bit of all NSViews which results in dramatically reduced performance. Until Apple fixes this severe bug, we work around this by patching NSKeyedUnarchiver to clear the bit during decoding of the compiled xib files. By the way: We filed this bug three months ago under rdar://14359398.

	@interface NSKeyedUnarchiver (Xcode5Fix)
	@end

	@implementation NSKeyedUnarchiver (Xcode5Fix)

	+ (void)load
	{
	[self exchangeInstanceMethod:@selector(decodeInt32ForKey:)
	withMethod:@selector(xcode5Fix_decodeInt32ForKey:)];
	}

How to make Xcode Server send notification e-mails from a DSL dialup line.

	Xcode Server notifies developers via e-mail (sadly no Jabber support yet) about the state of its integrations. In the default settings, Mavericks Server directly tries to send these messages. If your Xcode Server runs on a regular dialup DSL line, these messages will most likely be bounced as spam.
	To get it to work one needs to activate the relay option in the Server.app > Mail settings with the credentials of your e-mail ISP.
	But additionally I had to issue the following commands in Terminal.app to make it work:

	sudo postconf -c /Library/Server/Mail/Config/postfix/ -e "smtp_sasl_security_options = noanonymous"
	sudo postfix reload
	sudo postsuper -r ALL

Xcode Server has the problem that one can only access the build log files once the build or test process has finished. But as it can occur that tests hang, it is hard to analyze why and where the hang actually happened. This little shell script helps debugging by showing the log output of the currently running bot.

	#!/bin/bash
	# Shell script to be executed on a Mavericks Server runing Xcode Server using sudo
	BOTRUN_DATA=/Library/Server/Xcode/Data/BotRuns
	LATEST_RUN=`ls -tr $BOTRUN_DATA \| grep BotRun- \| tail -n1`
	tail -f ${BOTRUN_DATA}/${LATEST_RUN}/output/build.log

My former Jenkins build script for performing xcode tests using xctool

	rm -f ${WORKSPACE}/test-report.xml
	rm -rf /Users/jenkins/Library/Developer/Xcode/DerivedData
	rm -rf ${WORKSPACE}/Build/Products

	nice -n 20 /Users/jenkins/xctool/xctool -reporter pretty -reporter junit:${WORKSPACE}/test-report.xml -workspace MyWorkspace.xcworkspace -scheme MyScheme -configuration Debug SYMROOT=${WORKSPACE}/Build/Products test OTHER_CFLAGS='$(inherited) -Qunused-arguments -Werror'

	# Note the -Qunused-arguments is needed because xcodebuild adds unused compiler arguments about which clang complains a lot. Together with -Werror this results in failed builds. So we have to silence this kind of warning.

depth42 / Example for not breaking on certain exceptions

Last active August 9, 2016 14:14

Breaking on exceptions in Objective-C is cumbersome, because a breakpoint on objc_exception_throw cannot differentiate between an expected (caught) exception and an unexpected exception (like one from a failed assertion). To work around this, we intercept objc_exception_throw using mach_override and apply filter rules to decide whether to break …

	@implementation NSManagedObjectContext (PWExtensions)

	#ifndef NDEBUG
	// Core Data uses exceptions to notify itself about optimistic locking failures. These exceptions are intercepted by
	// Core Data and never reach the client code. Such an exception should not drop in the debugger because it is not raised
	// due to a programming error.
	// Since the exception is thrown inside -[NSManagedObjectContext save:], this category is a logical place to install
	// the filter.

Attempt at implementing a replacement for NSUnarchiver which is not available under iOS. This can be handy for reading legacy file-formats on iOS devices. It does not provide all features of NSUnarchiver but the basic stuff is there. Has been moved to https://github.com/depth42/MEUnarchiver
